1Introduction
1.1M
aster Plan Purpose and Objectives
InnServices Utilities Inc. (InnServices) retained C.C. Tatham & Associates Ltd. to update the Innisfil Town-wide W
ater and Wastewater Master Servicing Plan, which was last updated in March 2012.
The purpose of the Master Servicing Plan Update (MSP Update) is to identify short and long term strategies for water and wastewater servicing to accommodate the population and employment growth outlined in the Official Plan (2018) and OPA No. 1, and to improve servicing to existing residents, all in accordance with the goals and objectives of the Official Plan.
Key objectives of the MSP Update include:
Provide water and wastewater servicing to the planned population and employment growth to the year 2031, and consider an ultimate servicing vision;
Provide opportunities to extend servicing to existing residents in unserviced areas;
Include logical phasing plans and maximize the number of benefitting users, to improve affordability and facilitate implementation;
Achieve environmental protection and public health goals;
Coordinate with the 2018 Transportation Master Plan (TMP) to ensure that both studies are fully aligned and infrastructure projects are phased to avoid multiple disruptions to residents and business owners;
Include consideration of major rehabilitation and optimization projects to extend the life and functionality of the existing infrastructure.
1.2Report Organization
The report is organized as follows:
Chapter 2 describes the project approach, including the Master Plan Class Environmental Assessment process.
Chapter 3 outlines the general problem statement for the Class EA study.
Chapter 4 presents the current regulatory context in which the MSP Update was undertaken.
Chapter 5 provides a general description of the study area and profiles of Innisfil’s communities, and summarizes the population and employment projections.
Innisfil Master Servicing Plan Update Final Draft Report
Page 2 July 13, 2018
Chapter 6 reviews historical water demands and wastewater flows, suggests design criteria, and projects water and wastewater flows that will need to be accommodated.
Chapters 7 and 8 describe the Lakeshore water system and the Lakeshore wastewater system respectively, as these system serve the majority of the serviced population in Innisfil. Overall system needs are presented.
Innisfil’s servicing needs, solutions and recommendations are presented by community in Chapters 9 to 16. The communities are organized in four geographic areas, Innisfil North, Innisfil Central, Innisfil South, and Cookstown, as per the 2012 MSP.
Chapter 17 describes the public, stakeholder and agency consultation process and the comments that were received.
Chapter 18 presents the recommended servicing plans, the estimated infrastructure project costs, and suggests an implementation plan with priorities, triggers and timelines.
Innisfil Master Servicing Plan Update Final Draft Report
Page 3 July 13, 2018
2Project Approach
2.1M
aster Plan Class EA Process
The Master Servicing Plan update is developed under the MEA Municipal Class EA process for Master Plans, and following Approach #2. Requirements for Schedule A, A+ and B projects will be fulfilled and a Notice of Completion of the Master Plan EA, including these projects, will be issued upon completion of the study.
The Municipal Class EA is a planning and design process to identify, compare and evaluate alternative solutions to a problem. It applies to all municipal road, water and wastewater projects, and significant private projects. It considers all aspects of the environment: natural, social, cultural and economic, and involves consultation with the public, affected parties and review agencies throughout the process.
Master plans are long-range plans that integrate infrastructure requirements for existing and future land uses with environmental assessment planning principles.
The Master Servicing Plan update will proceed through the first two phases of the Class EA process:
Phase 1: Problem or opportunity identification
Phase 2: Identification and assessment, at a strategic level, of alternative solutions, then recommendation of the preferred solutions of the Master Plan that can be implemented as separate subsequent projects.
Projects that are considered Schedule A, A+, or B undertakings under the Municipal Class EA process can then move to implementation once the Notice of Completion of the Master Plan Class EA has been issued.
Projects that are considered Schedule C undertakings will proceed with separate and more detailed investigations to fulfill the documentation requirements of the Class EA process, including the completion of Phases 3 and 4 of the Class EA.
2.2Public and Agency Consultation Program
Public and agency consultation was an integral part of the development of the MSP Update. The general public, property owners, relevant government agencies, and adjacent municipalities were invited to provide input on the servicing needs and servicing alternatives at two Public Information Centres in November 2017 and March 2018. All comments and input received were taken into consideration for the evaluation of servicing alternatives and the updating of the servicing master plan. The Notice of Study Completion has been issued and the Final Draft MSP Update has been made available for review.

Innisfil Master Servicing Plan Update Final Draft Report
Page 5 July 13, 2018
3Problem
Statement
The MSP Update Class EA needs to identify the most appropriate water and sanitary servicing approaches to:
increase the municipal water and wastewater systems capacity (trunk mains, pumping stations and treatment) to accommodate the planned residential and employment growth to the year 2031 and beyond, including intensification and green field developments, as well as the connections of existing lots to the municipal systems;
extend servicing to areas that are currently unserviced, with priority to Innisfil’s growth areas, and to shoreline areas to reduce potential impacts on Lake Simcoe water quality; and,
improve the wastewater collection network and the water distribution network to address issues with inadequate flows and pressures.
The servicing approaches need to be coordinated and phased in a manner that maximizes the number of benefitting users to improve affordability and implementation.
The detailed servicing needs and issues are presented by area in Chapters 7 to 16.
Innisfil Master Servicing Plan Update Final Draft Report

4Regulatory Fram
ework
Water and wastewater systems in the Town of Innisfil are governed by a variety of provincial legislation
and policy. This section briefly describes the regulatory framework under which the MSP Update was completed.
4.1Planning
Developed under the authority of the Places to Grow Act, 2005, the Growth Plan for the Greater Golden Horseshoe (2006, Office Consolidation 2013) provides a framework for infrastructure investment, including water and wastewater infrastructure, in the Greater Golden Horseshoe area so that existing and future investments are optimized to serve growth to the year 2031 and beyond. The Growth Plan sets future population and employment targets for each municipality, including the Town of Innisfil, and requires that growth be accommodated through intensification in existing settlement areas.
The Provincial Policy Statement (PPS, 2014) is the statement of the province’s policies on land use planning, made under the Planning Act, 1990. The PPS establishes the Town of Innisfil’s role in planning for growth, intensification and redevelopment through the Town’s Official Plan. The PPS identifies that planning for sewage and water services must accommodate expected growth in a manner that promotes the efficient use of existing municipal and private communal sewage and water services.
The Town of Innisfil Official Plan (OP) is the principal document used to guide long range planning for the Town. In January 2018, Town of Innisfil Council adopted the “Our Place” Official Plan 2018 that guides development to the year 2031. It replaces the previous 2006 OP that was approved by the Ontario Municipal Board in May of 2009, March of 2010 and April of 2011. Official Plan Amendment No. 1 (OPA No.1) is the Town of Innisfil’s Growth Management Strategy. OPA No. 1 is a Town-initiated amendment that provides a policy framework for guiding population and employment growth in the Town to the year 2031. OPA No.1 was approved by the County of Simcoe in October 2009. It specifies a population target of 65,000 residents and an employment target of 32,500 by 2031.
Innisfil’s Our Place Official Plan (2018) presents a vision for managing and planning the growth of Innisfil in a manner that is responsible, deliberate and that provides sustainable and timely infrastructure. One of the OP’s goal is that growth be phased in tandem with infrastructure, and that expansion of the existing infrastructure be planned in an efficient and financially sustainable manner.
The Town of Innisfil updated its Transportation Master Plan (TMP) in March 2018. The TMP is a long-term plan to guide the Town towards a future transportation network to the year 2041. It meets the vision of the Town’s strategic plan (Inspiring Innisfil 2020), and builds on Provincial plans, County of Simcoe plans, and Innisfil’s Our Place Official Plan and Trails Master Plan. It considers the proposed Metrolinx Innisfil GO Station. The 2018 TMP update was taken into consideration in the preparation of the MSP

related to the treatment and distribution of drinking water, including the control and regulation of drinking water systems. The treatment and testing requirements for all the water systems that are or will supply drinking water to the Town of Innisfil are specified under (O. Reg. 170/03).
TheClean Water Act, 2006 (CW
A) mandates the protection of municipal drinking water sources. Under CW
A and its regulations, source water protection plans have been developed to protect the sources of municipal drinking water such as the groundwater wells in Churchill, Stroud and Innisfil Heights, and the surface water intake at the Lakeshore W
TP. Any new municipal intake or groundwater well for the supply of water to Innisfil must meet the requirements of the CW
A and be managed under a source protection plan. Innisfil is governed by the South Georgian Bay Lake Simcoe Source Protection Plan, which came into effect July 1, 2015.
4.3W
astewater
The construction and operation of wastewater treatment facilities in the Lake Simcoe basin are regulated under the Ontario W
ater Resources Act, 1990 (OWRA). The OW
RA sets out requirements for the planning, design, construction and operation of sewage works. The OW
RA specifies requirements that the Town must satisfy in order for the province to grant approval for establishing, altering, extending, or replacing wastewater system components.
TheLake Simcoe Protection Act, 2008 (LSPA) provides the framework for the development of the Lake Simcoe Protection Plan (LSPP) and sets out its objectives. The LSPP, issued in June 2009, sets objectives to reduce the discharge of pollutants and the loadings of phosphorus and other nutrients of concern to Lake Simcoe and its tributaries. It sets out policies that prohibit the establishment of new municipal sewage treatment plants in the Lake Simcoe watershed. A Phosphorus Reduction Strategy was published in June 2010. It set specific total phosphorus loading caps for each sewage treatment plant discharging to Lake Simcoe. Compliance with the Strategy is enforced through an Environmental Compliance Approval (ECA) for each facility. The ECA for Innisfil’s Lakeshore W
PCP sets the maximum total phosphorus load of 629 kg/year.

5.1.2Natural Environm
ent Features
Numerous streams and creeks stretch across the Town, many of which drain to Lake Simcoe, including W
ilson Creek just south of Lefroy, Innisfil Creek in the southeast and flowing into Bradford West
Gwillimbury, and Lovers Creek, which flows into Barrie to the north. Natural environment areas exist adjacent to the majority of these water bodies, as well as along much of the Lake Simcoe shoreline. Figure 2 shows the main natural environment features within the Town.
5.1.3Transportation
Innisfil’s transportation network includes provincial, county and local roads, trails, a new on-demand local transit service, and commuter transit service.
The major transportation corridor to Innisfil is Highway 400, which connects to the City of Barrie in the north and the GTA in the south. Access to/from Highway 400 is available at the Highway 89 interchange, connecting to Cookstown, and at the Innisfil Beach Road interchange, providing access to Alcona. Yonge Street (County Road 4) and 20
th Sideroad (County Road 39) are the other major north-south roads in Innisfil.
The GO Transit train line crosses Innisfil but currently doesn’t stop in Innisfil; GO Transit buses stop in Stroud and Churchill. A new GO train station is planned at the 6 th Line and 20 th Sideroad.
An update to Innisfil’s TMP was completed in 2018. It makes recommendations to improve the transportation network to accommodate the planned growth.
5.1.4W
ater and Wastew
ater Servicing
All Innisfil’s settlement areas are serviced by municipal water systems, as shown on Figure 3. The Town’s main water system, the Lakeshore water system (also referred to as the Innisfil Lake Simcoe Drinking W
ater System), is supplied by the Lakeshore Water Treatment Plant (W
TP) on Lake Simcoe. The W
TP services Alcona, Sandy Cove and Friday Harbour Resort, Lefroy-Belle Ewart, Gilford, Fennell’s Corners and Cookstown. It also supplies drinking water to the Town of Bradford W
est Gwillimbury. Three separate municipal groundwater systems serve Stroud, Churchill and Innisfil Heights. The remainder of Innisfil residents have individual private water supplies.
Alcona, Lefroy-Belle-Ewart, Sandy Cove and Friday Harbour Resort, and Cookstown are serviced by municipal sanitary sewer systems, as shown on Figure 4. The Lakeshore W
ater Pollution Control Plant (W
PCP) treats wastewater from Alcona and the shoreline, from Lefroy-Belle-Ewart to Big Bay Point. The Cookstown W
PCP serves Cookstown only. All other Innisfil residents rely on individual systems.

5.2.4Cookstow
n and Highway 400 and 89 Area
This service area includes Cookstown and the area east of Highway 400 at Highway 89, as shown on Figure 1.
Cookstown
Cookstown is a Village Settlement Area at the intersection of Highways 27 and 89. It has an estimated population of 1,200 and is expected to grow to over 3,000 persons. This includes development of all available lands within the settlement boundaries and intensification of the downtown commercial area.
Cookstown consists of residential neighborhoods with a downtown commercial area at the intersection of, and along, Highways 27 and 89 that is designated as a Heritage Conservation District. Cookstown has a community centre, park, curling club, library school, and several churches. A tributary of the Nottawasaga River crosses the western Cookstown boundary. A tributary of Innisfil Creek extends across the southern portion of the community just north of the W
PCP.
Cookstown is serviced by municipal water from the Lakeshore water system, and by the Cookstown sanitary sewer system and W
PCP. A Class EA study is ongoing for the expansion of the WPCP.
Highway 400 & 89 Area

5.3Projected Residential Grow
th
From the 2016 census, the total population of the Town of Innisfil is calculated to be 36,566 persons, living in a total of 14,875 private dwellings, with an average household size of 2.7 ppu (Statistics Canada).
The population of Innisfil is expected to grow steadily at a rate of 2% to 3%
over the next 20 years (Long Range Financial Plan, Hemson, 2016), meeting or exceeding the residential population target set in Schedule 7 of the Growth Plan of 56,000 persons by 2031. Population growth will include additional seasonal residents, resulting from the Friday Harbour Resort in particular, which is not included in the Growth Plan targets. The population growth is a result of Innisfil’s location in relative proximity to the
Innisfil Master Servicing Plan Update Final Draft Report
Page 20 July 13, 2018
GTA and along Highway 400, and on the shore of Lake Simcoe. Overall, the population of Innisfil is forecast to almost double in the next 20 years, which is unprecedented in the history of Innisfil.
It is projected that approximately 11,000 new housing units will be built in the 2011-2031 period, the majority of which will be built in Alcona and Lefroy-Belle-Ewart, as shown on Figure 5. Approximately 3,500 new housing units (Innisfil Municipal Residential Land Budget, 2016) will be built within the built-up areas, thus meeting the intensification target of 33%
specified in the Growth Plan. Most of the remainder will be within designated greenfield areas, which are in Innisfil’s settlement areas. The Town’s housing unit forecast exceeds the Growth Plan Schedule 7 forecast, however this is not an issue as the surplus will occur in lands designated for urban use.
Based on the 2011 census, the overall residential unit occupancy was 2.68 ppu in 2011. This occupancy is projected to decrease to 2.57 ppu by 2031 based on the projected housing mix (Innisfil Municipal Residential Land Budget, 2016). An average residential unit occupancy of 2.65 was used for this MSP Update.
5.4Serviced Residential Population Projections
For the purposes of updating the MSP, an estimate of the residential population that could be serviced by municipal water and wastewater systems in each settlement area and adjacent service area, is required. Existing and projected serviced population projections to the year 2031 and beyond were compiled by InnServices with the assistance of Innisfil’s planning department, based on a review of water and wastewater accounts, development plans, and the Town’s GIS information base. Projected serviced populations include existing properties in settlement areas to which water and wastewater infrastructure could be extended, infill lots, and planned developments.
Table 1 summarizes, by community, the estimated existing population that was serviced by municipal water and wastewater systems in June 2017, and the estimated total population that could potentially in the future be municipally-serviced with water and/or wastewater. The latter includes populations within existing settlement areas or in existing communities adjacent to serviced settlement areas. This MSP Update will review if, when, and how these currently unserviced areas should be serviced.
More detailed population projections are included in Appendix A. Table 1 indicates that approximately 58%
of Innisfil’s population currently has municipal water service, and 65% has municipal wastewater
service, assuming a residential population of 36,000.

The Town’s employment is also projected to increase significantly over the next 20 years, from approximately 8,700 jobs in 2014 to 13,800 jobs in 2034 (Long Range Financial Plan, Hemson, 2016), an increase of 5,100 new jobs. The projections indicate Innisfil will meet the Growth Plan Schedule 8 employment target of 13,100 jobs.
Over half of these jobs will be population-related employment. This includes retail, education, health care, municipal government, etc.Development of the Town Campus at Innisfil Beach Road and Yonge Street will contribute to the creation of these jobs. A health campus node is also under consideration at Yonge Street and the 6 th Line (6 th Line Campus Node).
A significant percentage of the forecasted new jobs will be based in the provincially-designated Innisfil Heights Settlement Employment Area, which will eventually encompass an area of 645 ha including its future expansion area, as shown on Figure 5. The number of jobs per hectare in the Innisfil Heights employment lands is expected to increase once the lands are fully serviced.

Historical water demands for each of the municipal water systems from the years 2012 to 2017 were compiled. Table 2 presents the data for the systems that supply mostly residential areas. Data for the Cookstown water system is not included as this system was connected to the Lakeshore water system in April 2013. Data for the Goldcrest water system is shown, however, Fennel’s Corners was also connected to the Lakeshore system in October 2016.
The data indicates that in general average day demands for the Lakeshore Water System have
increased as the number of connections have increased. Water demands at the Churchill, Goldcrest,
Innisfil Heights and Stroud water systems have remained relatively constant. For all systems, the average and maximum day water demands were lower in 2017, potentially attributed to the wet summer and associated decrease in lawn watering and summer occupancy.
Per capita water consumption in Alcona ranged from 232 L/p/day to 262 L/p/day and averaged 246 L/p/day. W
ater consumption in the smaller Churchill, Goldcrest and Stroud water systems show a wider range, from 211 L/p/day to 298 L/p/day, with an average of 256 L/p/day. Per capita water consumption was lower in 2017 for all communities.
The maximum day factor (MDF) in Alcona ranged from 1.6 to 2.3. In Stroud and Churchill, which serve a much smaller population, the MDF was slightly higher, ranging from 1.9 to 2.5.

The daily wastewater flows measured at the Lakeshore WPCP from 2007 to 2017, and at the Cookstown
WPCP from 2010 to 2017, were reviewed to determine the per capita wastewater generation rates. The
data was analyzed to separate the average and peak inflow and infiltration (I/I) rates from the domestic wastewater flow rates following the approach used for the Lakeshore W
PCP expansion Class EA study (Innisfil Lakeshore W
PCP Expansion ESR, 2010).
6.2.1Lakeshore W
PCP
As shown in Table 4, considering 9 years of data at the Lakeshore WPCP, the average per capita
wastewater generation rate was 352 L/p/day. Considering the past 5 years only, the average flow was slightly lower at 334 L/p/day. Of this average flow, a portion is considered base domestic flow and the other dry weather infiltration. The domestic wastewater flow averaged 288 L/p/day in the past five years. The 5-year average I/I contribution was 46 L/p/day. However, contribution of I/I to the average flow was higher in 2016 and 2017 than in previous years.
Analysis of the peak daily wastewater flow data shows that the per capita peak flow was lower in the past five years, averaging 716 L/p/day. The estimated wet weather I/I contribution to the peak flow varies: the highest per capita I/I was 560 L/p/day in 2016, less than was estimated based on earlier data.
6.2.2Cookstow
n WPCP
In Cookstown, as shown in Table 5, the historical data indicates an average per capita wastewater generation rate of 339 L/p/day over the last 8 years, and 323 L/p/day over the last 5 years. Domestic flow averaged 263 L/p/day in the past five years.
Peak per capita wastewater flow in Cookstown were higher than in the Lakeshore system. Peak flows averaged 920 L/p/day in the past 5 years. The estimated wet weather I/I contribution to the peak flows ranged from 500 L/p/day to 818 L/p/day.

Residential Water Consum
ption
The 2012 MSP used water design criteria for the urban areas of Alcona, Big Bay Point and Lefroy of 300 L/cap/day for existing residential areas and 275 L/cap/day for future residential areas. For all other communities, design criteria of 325 L/cap/day for existing residential areas and 300 L/cap/day for future residential areas, were used. The rationale for lower future per capita water usage for new developments was based on the tendency for new developments to have a higher density and smaller lots, and therefore water consumption for irrigation purposes is expected to be less.
The Town of Innisfil Engineering Design Standards (revised 2016) requires the use of an average per capita water demand of 325 L/p/day for new developments.
Innisfil Master Servicing Plan Update Final Draft Report
Page 29 July 13, 2018
Based on a review of historical water usage data (see Table 2), the water usage criteria in the 2012 MSP and in the Town Standards are considered too conservative and could be reduced for assessing capacity of existing water infrastructure and planning new infrastructure.
For the Lakeshore water system that serves Alcona, where most of the growth has occurred, water consumption averaged 246 L/p/day over the past 5 years. Accordingly for this MSP Update, a criterion of 250 L/p/day is used for future homes, while a criterion of 275 L/p/day is used for the existing areas, to account for less efficient water fixtures and larger lots.
For the smaller communities and water systems of Churchill, Stroud and Innisfil Heights, per capita water consumption is slightly higher than in the Lakeshore water system. For this MSP Update, a per capita water consumption criterion of 300 L/p/day is used for existing homes and a criterion of 275 L/p/day is used for future homes.
The Lakeshore water system data for the past 5 years indicate that the MDF varied between 1.6 and 1.9, except for a 2.3 MDF in 2016. The 2008 MOE Design Guidelines suggest a MDF of 1.9 for estimating the maximum day demands from residential areas with a population of 10,000 to 25,000, and 1.8 for populations of 25,000 to 50,000. In view of the historical data and of the projected increase in the population serviced by the Lakeshore water system, a MDF of 1.8 is used for this MSP Update.
For Churchill, historical water system data demonstrate a MDF ranging between 1.9 and 2.5 for a connected populations of 450. As no significant growth is anticipated, a MDF of 2.5 is used for planning purposes. Similarly for Stroud, which has a connected population of 1,720, a MDF of 2.3 is used in accordance with historical data.
Industrial and Comm
ercial Water Consum
ption
Industrial/commercial water consumption rates vary widely based on the type of industry. For master planning purposes, a rate of 10 m
3/ha/day is applied for light industrial uses that are limited by on-site septic systems. In the future however, when municipal wastewater servicing is extended to Innisfil Heights, an estimated water consumption of 20 m
3/ha/day could occur and should be planned for.
The above criteria for calculating water demands in Innisfil are summarized in Table 6.

Distribution System
The following minimum distribution system pressures are used in the assessment of the water systems, as outlined in the MOE Design Guidelines:
Normal operating pressures ranging from 350 kPa (50 psi) to 550 kPa (80 psi) under average day and maximum day demand.
Maximum pressures should not exceed 620 kPa (90 psi).
Minimum pressure of 275 kPa (40 psi) under peak hour demand.
Minimum pressure of 140 kPa (20 psi) under maximum day demand plus fire flow conditions.
Velocity in all watermains should not exceed 2 m/s under maximum day conditions.
Fire Flows
The Town of Innisfil Engineering Design Standards (revised 2016), require minimum fire flows of 38 L/s in residential areas and 75 L/s in industrial areas. The Town’s Standards also require that the 1999 Guidelines by the Fire Underwriters Survey (FUS) entitled: “W
ater Supply for Public Fire Protection” be applied.
The FUS guidelines outline a methodology for estimating the fire flow requirements for municipal fire protection on a building by building basis, based on materials of construction, size, fire protection, proximity to other buildings, etc. Although the required fire flows calculated using the FUS approach can vary significantly, the FUS guidelines include a simplified approach for detached and small two-family dwellings that provide useful guidance for planning for fire flows. FUS suggests that adequate fire flows for small detached and semi-detached homes could range from 33 L/s to 100 L/s, as follows:
Less than 3 m apart: 100 L/s Spaced 3 to 10 m apart: 67 L/s Spaced 10 to 30 m apart: 50 L/s Greater than 30 m apart: 33 L/s
For the purpose of this MSP Update, a range of fire flows of 38 L/s to 100 L/s is used for evaluating the available fire flows within existing and proposed residential areas, depending on the home density. Higher fire flow rates are required for multiple/attached townhomes and apartment buildings and should be calculated using the FUS methodology based on the specific characteristics of the proposed buildings. A fire flow duration of 2 hours, as recommended by FUS for fire flows of 6,000 L/min (100 L/s), is considered the minimum duration to provide adequate fire protection.
For the Lakeshore water system, due to the large population served, the MOECC suggested criterion of 378 L/s for 6 hours for an equivalent population of 40,000 persons, is used in this MSP Update to assess the adequacy of the water storage facilities.
Innisfil Master Servicing Plan Update Final Draft Report
Page 31 July 13, 2018
For the Innisfil Height employment area, the new reservoir and booster pumping station were designed and built to supply a fire flow of 190 L/s for 3 hours.
In summary, the MSP evaluates storage and pumping capacity requirements based on the following criteria:
Lakeshore water system storage: 378 L/s for 6 hours
Innisfil Heights and other employment areas: 190 L/s for 3 hours
Distribution systems in new residential areas: minimum of 100 L/s for 2 hours
Distribution systems in existing residential areas: minimum of 38 L/s for 2 hours
6.3.2W
astewater Criteria
Residential Wastew
ater Flows
Analysis of wastewater flows in the past 5 years indicate that the average daily per capita wastewater flow was similar in the Alcona and the Cookstown systems: 334 L/p/day at the Lakeshore W
PCP and 323 L/p/day at the Cookstown W
PCP. Overall, there is no decrease in per capita average wastewater flows in the past 5 years.
For this MSP Update, based on a review of historical data (Tables 4 and 5), an average per capita wastewater generation rate of 350 L/p/day is used for existing sewered areas. As lower per capita wastewater flows are projected in newly sewered areas, a lower average per capita wastewater criterion of 325 L/p/day is used for future sewered areas. These criteria are more conservative than the values previously used in the 2012 MSP (275 L/p/day to 325 L/p/day), but reflect more closely the historical data.
Inflow and Infiltration
Peak wastewater flows are calculated by applying the Harmon peaking factor to the domestic component (average dry day) of the wastewater flows, and adding a peak I/I flow.
Based on the historical peak I/I rates, a peak I/I of 600 L/p/day is used for the existing areas in the Lakeshore system, and a peak I/I of 800 L/cap/day is used for existing areas in Cookstown.
For future sewered areas, a peak I/I rate of 400 L/p/day is a conservative value that corresponds with MOECC guidelines. A lower peak I/I rate is justified because new infrastructure installed using newer and better construction methods can be expected to result in lower inflow and infiltration contributions.
Innisfil Master Servicing Plan Update Final Draft Report

Industrial and Comm
ercial Wastew
ater Flows
An average day wastewater flow generation rate for future industrial and commercial area of 20 m
3/ha/day is used in the MSP Update. It is acknowledged that wastewater flow rates can vary significantly depending on the type of commercial or industrial operations. A value of 20 m
3/ha/day is considered conservative and appropriate for planning purposes. A peaking factor of 2 is used to account for peak inflow and infiltration and daily variations in flow rates. These values are consistent with MOECC guidelines and standards in other communities.
Table 7 summarizes the above criteria used for calculating wastewater flows. The peak residential wastewater flows are calculated as follows:
Residential Peak Flow = (Average Domestic Flow x Harmon) + Peak Inflow and Infiltration

7Lakeshore W
ater System
The Lakeshore water system supplies drinking water to Alcona, the Leonards Beach shoreline, parts of Lefroy, Gilford, Fennel’s Corners and Cookstown, as well as to the Friday Harbour Resort. It also supplies drinking water to the Town of Bradford W
est Gwillimbury. The current extent of the Lakeshore water distribution system is shown on Figure 3. This chapter describes the components of the Lakeshore water system as well as the system needs and issues and recommended upgrades.
7.1Lakeshore W
ater System Description
7.1.1Lakeshore W
ater Treatment Plant
The Lakeshore water system (Innisfil Lake Simcoe Drinking Water System) is supplied by the Lakeshore
WTP, located on the 25 th Sideroad just north of Innisfil Beach Road in Alcona, beside Innisfil Beach
Park.
Phase 3A expansion of the WTP is under construction and expected to be in operation in the fall of 2018.
Two subsequent expansion phases are planned, Phases 3B and 3C. These expansions will increase the W
TP production from its current capacity of 25.8 ML/day as follows:
Phase 3A: 38 ML/day (at 20°C) and 30 ML/day (at 3°C). Phase 3B: 55 ML/day (at 20°C) and 44 ML/day (at 3°C). Phase 3C: 85 ML/day (at 20°C) and 68 ML/day (at 3°C).
The Lakeshore WTP treats water from Lake Simcoe, drawn from a 900 mm intake pipe, approximately
500 m long. A low lift pumping station houses the raw water screens and four pumps. The WTP
expansion will include replacement of the low lift pumps in stages with higher capacity vertical turbine pumps equipped with VFDs.
For the Phase 3 WTP expansion, the existing media filters and flocculation/clarification units will be
removed and replaced with a 2-stage membrane filtration system. The existing five GAC contactors for seasonal taste and odour control will be retained and three new contactors will be added.
The existing WTP uses chlorination and a chlorine contact tank for primary disinfection. Two new UV
units will be added upstream of the new membrane filters for primary inactivation of Cryptosporidium and Giardia. Chlorine will be added to the high lift pumping station discharge header for maintenance of residual in the distribution system.
The high lift pumping station that pumps treated water from the clear wells to the distribution system has four 110 L/s vertical turbine pumps. A fifth pump, with a capacity of 289 L/s and equipped with a VFD, will be added, increasing the firm high lift pumping capacity to 440 L/s in Phase 3A.
Innisfil Master Servicing Plan Update Final Draft Report
Page 34 July 13, 2018
The existing 600 kW standby generator is to be replaced with a 1250 kW
diesel generator. The new generator will provide 36 hours of standby power to the expanded W
TP.
7.1.2Alcona Reservoir
Water treated at the Lakeshore W
TP is conveyed to the Alcona Reservoir via a 500 mm watermain on Innisfil Beach Road.
The Alcona Reservoir is a two-cell grade level 8,700 m3 water reservoir located on Innisfil Beach Road,
west of the 20 th Sideroad. It provides storage to meet the peak hour demands, to supply fire flow when required, and for other emergencies.
Provision was made during the design for a subsequent expansion with a third cell for a total volume of 13,050 m
3.
7.1.3Pressure Zones
The Lakeshore water system has several pressure zones. Pressure zone boundaries are generally determined based on elevation and the design operating pressures of the pumps and reservoirs that service a particular area. The Lakeshore water system’s pressure zones are as follows:
There are two pressure zones in Alcona, with the boundary between Pressure Zones 1 and 2 at an approximate ground elevation of 250 m. The majority of Alcona’s existing residents and the Leonards Beach shoreline are in the lower Alcona Pressure Zone 1, supplied by the Alcona reservoir and the high lift pumps at the Lakeshore W
TP. The higher elevation areas of Alcona are in Pressure Zone 2 and are supplied by the Alcona Zone 2 BPS.
In Lefroy-Belle-Ewart, areas serviced by the Maple Road/Belle Aire Beach Road trunk watermain east of the rail line are in the Alcona Pressure Zone 1. Higher elevation areas west of the rail line and at an elevation above 230 m are in the Lefroy Pressure Zone 2, which is supplied by the Lefroy BPS and reservoir.
Gilford is in a separate pressure zone, controlled by a pressure reducing valve on the connection to the Innisfil-BW
G water transmission main.
Fennell’s Corners is in a separate pressure zone serviced by the Goldcrest standpipe and BPS.
Cookstown has one pressure zone serviced by the two Cookstown standpipes.
Figure 6 presents the pressure zones in Alcona and Lefroy-Belle Ewart.

A booster pumping station at the Alcona Reservoir supplies water to the Town Campus at Yonge Street and Innisfil Beach Road, that comprises the Town Hall, the Multi Use Recreational Facility (MURF) and a new private school. The BPS at the Alcona Reservoir has a capacity of 8.7 L/s and pumps via a 150 mm watermain along Innisfil Beach Road to the Town campus water system.
The Town Campus water system consists of a 460 m3 reservoir and a BPS with three vertical turbine
pumps, two with capacities of 15.8 L/s and VFDs and one with a capacity of 47 L/s. This system provides drinking water and fire protection to the existing buildings.
7.1.5Alcona Zone 2 Booster Pum
ping Station
The Alcona Zone 2 BPS, located at the south west corner of Innisfil Beach Road and Webster Boulevard,
supplies Alcona Pressure Zone 2. It houses four in-line vertical turbine pumps, equipped with VFDs (one pump at 31 L/s, two pumps at 62 L/s, and one pump at 90 L/s), providing a firm capacity of 155 L/s. A diesel generator set provides stand-by power.
7.1.6Innisfil-BW
G Water Transm
ission Main and Third Line Booster Pum
ping Station
The 26 km long Innisfil to BWG water transmission main (W
TM) delivers treated water from the Alcona reservoir to the John Fennel grade-level reservoir in BW
G, located on the 10th Sideroad south of the 12 th
Line. Water flows to BW
G are measured at a monitoring station in Fennell’s Corners.
From Alcona to Lefroy, the water transmission main is 600 mm in diameter and is routed along Innisfil Beach Road and the 20 th Sideroad. From Lefroy to the BW
G reservoir, the transmission main is 500 mm in diameter and runs along the 20 th Sideroad, Highway 89 and Yonge Street. Connection points provide water to Lefroy, Gilford, Fennell’s Corners and Cookstown. The W
TM was designed to convey 170 L/s to communities in Innisfil and 180 L/s to BW
G for a total flow of 350 L/s.
The Third Line BPS, located on the 20 th Sideroad at the 3 rd Line, boosts the pressure in the Innisfil-BWG
water transmission main to supply water to BWG, Cookstown, Gilford and Fennell’s Corners. The Third
Line BPS houses four constant speed vertical turbine pumps installed in cans, with a firm capacity of 108 L/s, and a diesel generator set. It is designed for a Phase 2 expansion to increase the firm pumping capacity to 185 L/s.
The design of an expansion of the Third Line BPS and twinning of the water transmission main from the BPS to the BW
G reservoir is currently underway, in order to increase the water supply to BWG from 13
ML/day to 25.4 ML/day.

7.1.7Goldcrest W
ater System
The Goldcrest water system serves Fennell’s Corners. It was, until 2017, supplied by groundwater wells. The wells have been decommissioned and the groundwater supply has been replaced with a supply from the Alcona to Bradford water transmission main.
The Goldcrest water system consists of a 483 m3 standpipe and a BPS with four constant speed, inline
vertical pumps with capacities of 2.5 L/s, 8.7 L/s (2 pumps), and 38 L/s (fire pump). A standby diesel generator provides emergency power to the entire BPS.
7.1.8Cookstow
n Water System
The Cookstown water distribution system is supplied from the Lakeshore water system via a trunk water main on Highway 89 connected to the Alcona to Bradford water transmission main. Prior to 2013, Cookstown was supplied by a communal groundwater system.
Treated water storage in Cookstown is provided by two standpipes that have a combined capacity of 1,908 m
3 and a usable capacity of 1,466 m3. The original (west) standpipe is a painted steel standpipe
that was constructed in the 1970s. The east standpipe is a glass-fused-to-steel standpipe, constructed in 1990.
7.1.9Lefroy W
ater System
The Lefroy reservoir and BPS facility is located at the southeast corner of the 20 th Sideroad and Belle Aire Beach Road.
The reservoir is supplied from the trunk watermain on Belle Aire Beach Road, and can also be supplied from the Alcona to Bradford water transmission main in an emergency. The Lefroy reservoir is a two-cell grade level tank with a total volume of 2,100 m
3. It is designed for two additional cells to double the storage volume to 4,200 m
3. A second expansion is also possible on the site. The Lefroy reservoir was designed to supplement the Alcona reservoir to provide fire protection, flow equalization and emergency storage for the entire Lakeshore water system.
The Lefroy BPS pumps water from the reservoir into the Lefroy Pressure Zone 2 by four vertical turbine pumps, providing a firm capacity of 217 L/s. This capacity is sufficient to supply a fire flow of 190 L/s. The BPS is designed for a stage 2 expansion that will involve the replacement of one of the pumps to double the capacity to meet the domestic water demands in Lefroy Pressure Zone 2 from an equivalent population of approximately 3,900.
7.1.10Friday Harbour W
ater System
The Lakeshore water system supplies water to the Friday Harbour Resort in Big Bay Point via the trunk watermain on 25 th Sideroad. In Friday Harbour, the system includes a water standpipe with an operating
Innisfil Master Servicing Plan Update Final Draft Report
Page 38 July 13, 2018
volume of 3,306 m3. The standpipe was designed to provide the required storage volume for Friday
Harbour Resort, the golf course and the existing Big Bay Point community, and to supply a fire flow of 166 L/s for 2 hours. It includes a re-chlorination facility.
7.2Overall Lakeshore W
ater System Needs
The capacity of the Lakeshore WTP to supply the existing and projected water demands, and the
available treated water storage volume in all the reservoirs in the Lakeshore water system, were assessed to determine if there are any existing or projected shortfalls. Detailed calculation tables are included in Appendix A, Table A3.
7.2.1W
ater Storage Requirements
As summarized in Table 8, the Lakeshore water system currently has 16,055 m3 of available storage
volume in five reservoirs (including the newly built standpipe at Friday Harbour Resort), to meet peak water demands and provide fire protection. This storage volume is sufficient to meet the needs of the currently connected population.
With the planned expansions of the reservoirs in Alcona and Lefroy, Innisfil will have a total storage
volume of 22,915 m3. This volume represents 98%
of the calculated storage volume requirement of 23,320 m
3 for the projected serviced populations of 63,000 to the year 2031 in the existing service areas (see Table 9). The planned water storage expansions are therefore adequate for the needs to 2031, and based on current projections, will need to be constructed and commissioned by 2031.
Considering anticipated growth beyond 2031, a water storage shortfall of approximately 3,000 m3 is
forecasted, mainly for Alcona and Cookstown. A review of the water storage needs will be required as the serviced population and serviced industrial/commercial lands reach 75%
of the 2031 projections.

7.2.2W
ater Supply and Treatment Capacity
The maximum day demand in the Lakeshore water system’s service areas of Alcona, Sandy Cove, Big Bay Point, Lefroy, Gilford, Fennell’s Corners and Cookstown is projected to increase from the current demands of 7,800 m
3/day (2017 MDD) to 33,200 m3/day in 2031 if all proposed developments are built
and all currently unconnected properties in the current serviced areas connect to the water distribution system. Further, as described in Chapters 9 and 11, other service areas are proposed to be connected to the Lakeshore water system, namely Innisfil Heights and Stroud, both by 2031.
In addition, the Town of BWG is planning to gradually increase its water taking from the Lakeshore water
system from the current maximum rate of 7,200 m3/day (2017 MDD) to 25,400 m
3/day by 2031. It is noted that BW
G is revising its projected water servicing needs and may extend the period by which this water flow will be required.
Table 10 summarizes the current and projected water demands from the Lakeshore WTP and the
proposed WTP Phase 3 expansion capacities. As the Phase 3 expansion utilizes membrane filtration,
the actual treatment capacity varies with the water temperature. The higher treatment capacity is achieved when the raw water is warmest, which is also when the maximum water demands typically occur (in the summer).
Innisfil Master Servicing Plan Update Final Draft Report
Page 40 July 13, 2018
The Phase 3A WTP expansion, which will be commissioned in the fall of 2018 will accommodate a
doubling of the 2017 maximum day water demands. The Phase 3B WTP expansion will include a
twinning of the water intake. The Phase 3C WTP expansion is projected to need to be built by 2031 to
meet the projected 2031 water demands. However, the timing of the Phase 3B and Phase 3C expansions need to be reviewed in the next 5 years because the projected number of new connections and the estimated water usage in the expanded Innisfil Heights employment lands are conservative.
In summary, the planned Lakeshore WTP expansions are projected to provide sufficient treated water
for both Innisfil and BWG’s needs to the year 2031.
The Lakeshore WTP capacity can be increased beyond the currently planned expanded capacity, on
the existing site. A Class EA study for an expansion to a capacity of 99.7 ML/day was completed in 2011.

8Lakeshore W
astewater System
The Lakeshore wastewater system serves Alcona, a portion of Leonard’s Beach and Sandy Cove Acres in Innisfil North, as well as Innisfil South to and including Lefroy-Belle-Ewart. The Lakeshore wastewater system consists of a network of sanitary sewers, seven sewage pumping stations, and the Lakeshore W
PCP, as shown on Figure 4.
8.1Lakeshore W
astewater System
Description
8.1.1Sew
age Pumping Stations
The sewage pumping stations and their service areas are described below. Their current capacity and the projected peak flows resulting from growth in their service area are summarized in Table 11.
SPS #1
SPS #1 receives sewage flows from the serviced areas of Lefroy Belle-Ewart and pumps directly to the Lakeshore W
PCP. A capacity upgrade was completed in 2017 including new pumps and a second forcemain. This upgrade will provide sufficient capacity to convey the projected flows to 2031 from Lefroy, as well as eventually from Degrassi Point, Gilford and Churchill.
SPS #2
SPS #2, located on 6 th Line, receives sewage flows from a small area of the Big Cedar Point Shoreline. Its forcemain discharges to the headworks of the Lakeshore W
PCP. The SPS was upgraded with a new PLC and SCADA system in 2015/2016, and new pumps were installed in 2016.
A new and larger pumping station has been designed to provide sufficient capacity to convey flows from the 6 th Line developments (Sleeping Lion) as well as from the Alcona South growth area and the Innisfil Heights employment area. The new SPS #2 will be located on the 6th Line, and will discharge directly to the Lakeshore W
PCP. The new SPS # 2 will be built in two phases; the first phase will have a capacity of 355 L/s. The existing SPS #2 is expected to be maintained to provide service to its existing service area until a connection is made to the new SPS #2.
SPS #3
SPS #3, located on Cedar Grove Avenue, receives sewage flows from Alcona, including from SPS #4 and SPS #7, as well as from the serviced portions of Leonards Beach and Sandy Cove, and from the new trunk sewer that services Friday Harbour Resort. SPS #3 was upgraded in 2014.

SPS #7
SPS #7 serves a small area in Alcona North, and can be eliminated by extending the gravity sewer system through to Spring Street. This will occur once future planned development on Spring Street proceeds.
SPS #8
SPS #8, on Mapleview Drive just west of 25 th Sideroad, was constructed in 2017. It receives wastewater from Friday Harbour Resort and was designed to accommodate flows from the existing Big Bay Point community. It is designed for a second phase expansion as Friday Harbour Resort develops.
SPS #9
SPS #9 is located within Friday Harbour Resort and was recently assumed by InnServices. It conveys wastewater from Friday Harbour Resort to the 25
th Sideroad. It was designed to accommodate flows from the existing Big Bay Point community. It is designed for a second phase expansion as Friday Harbour Resort develops.
8.1.2Lakeshore W
PCP
The Lakeshore WPCP, located on St. John’s Road, just north of the 6 th Line, has an average day rated
capacity of 14,370 m3/day and a peak flow capacity of 39,960 m
3/day. The WPCP is an extended
aeration activated sludge facility, with tertiary filters and UV disinfection. The treated effluent is discharged to an outfall to Lake Simcoe with a capacity of 51,322 m
3/day. The WPCP was last expanded
in 1996. A septage receiving facility was recently added.
In 2017, the WPCP treated an annual average daily flow of 10,700 m
3/day, which corresponds to 74%
of its average day rated capacity. The peak flow was 24,000 m3/day or 60%
of the peak flow capacity. The W
PCP has been performing well and meets its effluent quality compliance criteria consistently, including its total phosphorus effluent limit of 0.3 mg/L
A Municipal Class EA study, including pilot tests of tertiary phosphorus removal technologies, was completed in 2011 for its expansion to an average day capacity of 40,000 m
3/day to accommodate planned growth. The expansion is planned to be completed in two stages: the first expansion stage (Stage 3) will expand the facility to an average day capacity of 25,000 m
3/day and will add membrane filtration for tertiary phosphorus removal. The second expansion stage (Stage 4) will increase the capacity to 40,000 m
3/day and will involve modifying the secondary treatment process to a conventional activated sludge process with biological nutrient removal. The W
PCP must not discharge more than 629 kg/year of phosphorus into Lake Simcoe, now and in the future. As a result, the Stage 3 expansion must meet an effluent phosphorus limit of 0.069 mg/L, and the Stage 4 expansion must achieve an effluent phosphorus limit of 0.043 mg/L.
Innisfil Master Servicing Plan Update Final Draft Report
Page 44 July 13, 2018
InnServices is considering changes to the WPCP’s biosolids management approach to reduce capital
and operating costs that will be assessed in detail during the design of the WPCP expansion.
8.2Overall Lakeshore W
astewater System
Needs
8.2.1Lakeshore W
PCP Capacity
As the WPCP reached 75%
capacity in 2017, and significant growth is planned by 2031, implementation of the plans to expand the W
PCP need to start in the very short term. Wastewater flows in 2017 were
20% higher than in 2016. Review of the flow data and customer counts indicates this increase can be
attributed to both a significant increase in the number of connections to the municipal sewers and to extraneous flows from I/I into the sewers from the many wet weather events in 2017.
Table 12 summarizes the existing and projected wastewater flows and the planned WPCP expansion
capacities.
Average day wastewater flows to the Lakeshore WPCP are projected to reach 21,300 m
3/day by 2031 from servicing growth and from connections of existing properties in the existing service areas. If the Innisfil Heights economic district is connected to the Lakeshore wastewater system, flows could reach 28,000 m
3/day by 2031, exceeding the planned Stage 3 WPCP expansion capacity of 25,000 m
3/day.However, the Stage 4 W
PCP expansion may not need to be constructed by 2031 as the wastewater generation rate used for projecting flows from the Innisfil Heights employment lands is conservative. Similarly, the Stage 4 W
PCP expansion may be adequate for the currently projected wastewater flows beyond 2031.
When the actual wastewater flows plus the allocated wastewater flows to the W
PCP reach approximately 75%
of the WPCP average day capacity, design of the next expansion stage should be initiated.

The wastewater flow projections are based on historical domestic flows and I/I contributions. Controlling and eliminating sources of I/I into the sewer system is necessary to ensure the W
PCP will continue to have sufficient capacity to accommodate the planned growth in Innisfil. The Stage 4 W
PCP expansion will utilize phosphorus removal technology that is capable of achieving an effluent concentration of 0.04 mg/L in order to meet the Lake Simcoe Protection Plan maximum annual phosphorus load. This effluent compliance concentration is very close to the limit of technology for phosphorus removal. Any further expansion of the W
PCP will need to meet an extremely low effluent phosphorus concentration to stay within the maximum phosphorus load to the lake, and will therefore be very expensive.
An alternate approach to reducing the total phosphorus load to the lake is for the reuse of WPCP effluent
for irrigation or other industrial purposes, thus diverting effluent from Lake Simcoe. The technical and financial feasibility of a ‘Purple Pipe’ from the W
PCP to Innisfil Heights should be evaluated upon development of the Innisfil Heights economic district.
There are no known deficiencies with respect to the Lakeshore WPCP that need to be addressed in the
short term. Any required upgrades will be implemented as part of the WPCP expansion project.
8.2.2Sew
age Collection System Upgrades
All sewage pumping stations have sufficient capacity for current peak wastewater flows, as summarized in Table 11. Two pumping stations, SPS #3 and SPS #4 will need to be expanded for the projected wastewater flows, and the capacity of some sanitary sewers will be exceeded. Further details are presented in Section 10.1.
Operating staff have reported that for all SPS, none of the forcemains and air relief valves have been inspected or maintained within the last 16 years. A condition assessment of all forcemains and ARVs is needed in order to plan for proactive maintenance.
SPS #2
A new SPS #2 has been designed to convey the wastewater flows from proposed developments on the 6 th Line east of 20 th Sideroad, the proposed GO Station, and ultimately from the expansion of the Innisfil Heights employment lands and the potential Campus Node, directly to the Lakeshore W
PCP. Construction of this new SPS #2, to be located near the intersection of Saint John’s Road and 6
th Line, is scheduled for 2019. The new SPS #2 is also intended to replace the existing SPS #2 located at the east end of 6 th Line.
Construction of a new sanitary sewer from the east end of 6 th Line west to Saint John’s Road to convey the flows from the existing SPS#2 to the new SPS #2 is expected to be very difficult due to the resultant deep grades (9 m at Saint John’s Road), construction impacts to existing properties, abandonment of the existing sewer, service connections to a deep sewer, the existing 800 mm diameter W
PCP effluent outfall, and the high groundwater and poor soil conditions in this area. These issues could be eliminated
Innisfil Master Servicing Plan Update Final Draft Report
Page 46 July 13, 2018
by keeping the existing SPS #2 and forcemain in operation, thus avoiding the need to construct a new gravity sewer east of Saint John’s Road. The estimated construction cost of a new gravity sewer on 6 th
Line east of Saint John’s Road is in the order of $1M and would entail significant risk of construction issues. As the annual operating costs of the existing SPS #2 are low ($10,800 per year in 2017) and upgrades were recently completed, costs of maintaining the existing SPS are lower than constructing a new gravity sewer. Maintaining the existing SPS #2 is recommended.

9Innisfil North W
ater Servicing
The water servicing needs in Innisfil North, which includes Alcona, Big Bay Point, Leonards Beach, Sandy Cove, and Stroud, are described in this chapter. Alternative solutions, their assessment and the preferred solutions are outlined, by community.
9.1Alcona and Tow
n Campus
9.1.1Existing W
ater Servicing Issues
The following existing issues with the Lakeshore water system within Alcona have been identified:
Operating Pressures in Alcona Pressure Zone 2
The discharge pressure from the Alcona Zone 2 BPS is limited to 64 psi in order to prevent pressures from exceeding 80 psi at the lower elevations of the pressure zone. As a result, normal operating pressures under MDD conditions in the highest elevation area of Alcona Pressure Zone 2 are as low as 42 psi, which is below the MOECC recommended minimum pressure of 50 psi under MDD conditions.
Available Fire Flows in Alcona
Analysis of the water distribution system using the WaterCAD model indicates that available fire flows
under MDD conditions in Pressure Zones 1 and 2 are mostly at or above 100 L/s. This is acceptable in most situations. However, fire flows as low as 36 L/s are found at some watermain dead ends. These fire flows are low compared to FUS suggested fire flows, however are close to the minimum criteria in the Town’s Engineering Design Standards of 38 L/s in residential areas.
9.1.2Future W
ater Servicing Needs
Considering the water servicing requirements associated with the planned growth in Alcona, the following future needs have been identified:
Growth and Intensification
Future residential and employment growth and intensification in the serviced areas of Alcona and Leonards Beach will be serviced by additional connections to the Lakeshore water distribution system, and by the planned Lakeshore W
TP expansions. This includes the proposed GO Station at the 6 th Line.
However, the planned growth areas in Alcona North and Alcona South will be in Pressure Zone 2 and at elevations beyond the upper limit of Pressure Zone 2. The Alcona Zone 2 BPS has limited capacity for growth in Alcona Pressure Zone 2. Booster pumping capacity into a third pressure zone needs to be considered for the higher elevation areas.
Innisfil Master Servicing Plan Update Final Draft Report
Page 48 July 13, 2018
Intensification in the existing areas of Alcona where fire flows are low may require improved water distribution main looping, and where possible, connection with a PRV to a higher pressure zone.
Innisfil Beach Road Trunk Waterm
ain Capacity
WaterCAD analysis indicates that the trunk watermain on Innisfil Beach Road from the Lakeshore W
TP to the Alcona Reservoir will not have sufficient capacity to accommodate the cumulative demands from future growth in Alcona, from growth in BW
G, and from the Innisfil Heights employment area when it is connected to the Lakeshore water system. An additional 600 mm diameter trunk watermain is needed from the Lakeshore W
TP to the Alcona Reservoir.
Town Cam
pus Servicing
New institutional developments at the Town Campus site, such as the new private school and its planned expansion, and the proposed medical offices, require an adequately sized water supply system to replace the current water system that was designed for the Town’s municipal offices and the MURF only. The Town Campus is identified in Innisfil’s Our Plan Official Plan as an area where future major government and cultural facilities shoud be considered and where related commercial developments may occur.
9.1.3Description of Alternative Solutions
The solutions to the identified water servicing needs and issues in Alcona are closely interrelated.
The need to expand the trunk watermain capacity to supply water from the Lakeshore WTP to the Alcona
Reservoir can be addressed by adding a second 600 mm diameter trunk watermain. The option of twinning the trunk watermain on Innisfil Beach Road is not a viable option as it would result in significant disruption to this major commercial road, which was recent reconstructed. The only viable route from the W
TP through existing municipal roads is north on the 25 th Sideroad, west on the 9 th Line and south on 20 th Sideroad to Innisfil Beach Road. This watermain alignment would cross the rail line at 20
th
Sideroad and Innisfil Beach Road, where a sleeve is planned to be installed for this watermain when the intersection is rebuilt in 2019. This proposed new trunk watermain and alignment are taken into consideration in the development of alternative solutions for water servicing of Alcona’s growth areas, as described below.
The land on the Town Campus and at the intersection of Yonge Street and Innisfil Beach Road is anticipated to continue to develop as it is identified in the Town’s Official Plan as a government/cultural growth area. W
ith the upcoming construction of the IHP Health Hub and the recently built school, a reliable and adequate water supply solution must be provided to the area. Expanding the existing small water supply system and Town Campus reservoir is not a feasible long-term solution because of the physical limitations of the water works site and pumping facilities. The extension of the Lakeshore water distribution system west from the Alcona Reservoir on Innisfil Beach Road to Yonge Street is a viable

solution that can be designed to meet future needs of the Town Campus as well as of future service areas to the west (Innisfil Heights economic district), north (Stroud) and south (Campus Node). The lands west of 20 th Sideroad, including the Town Campus, are at higher elevations and outside of the Alcona Pressure Zone 1. A BPS is required to supply water at the required operating pressures. The Town’s Alcona Reservoir site has adequate area to accommodate a BPS, therefore this municipally-owned property is the recommended location for a new BPS.
To address the identified water servicing needs in Alcona’s North and South growth areas, the following alternative solutions were considered:.
Alt. 1. Supply the North growth area from the Alcona Zone 2 BPS and from a new Zone 3 BPS; and supply the South growth area from a new BPS at the Alcona Reservoir site.
Alt. 2: Supply the North growth area from a new 9 th Line trunk water main and a new Zone 2 BPS; and supply the South growth area from an expansion of the Lefroy Zone 2 BPS.
Alternative 1 is shown on Figure 7. It would involve utilizing available capacity at the Alcona Zone 2 BPS to supply water to the portion of Alcona North that is in Pressure Zone 2. As the Zone 2 BPS is now operating at a lower discharge pressure than it was designed for, the pumps can operate at a higher discharge rate, which is sufficient to meet the peak hour needs of Alcona North in Pressure Zone 2. The Zone 2 BPS would require upgrades, including: adding a variable frequency drive (VFD) on the high lift pump that is currently used for fire flow so that it can also be used to meet the peak water demands, replacing the emergency generator, and control modifications.
A new in-line Zone 3 BPS would be required in Alcona North to provide the required pressures for the properties at the highest elevations. This new Zone 3 BPS would pump water from the new trunk watermain on the 9 th Line that is proposed to increase the watermain capacity between the Lakeshore W
TP and the Alcona reservoir.
Trunk watermains to the Alcona South growth area, which is also in Pressure Zone 2, would be supplied from dedicated high lift pumps at the new BPS to be located at the Alcona Reservoir site. New 300 mm diameter trunk watermains would be located on 20 th Sideroad and 6 th Line. For the small area in Alcona South that is at higher elevations, individual booster pumps would be recommended.
Alternative 2 is shown on Figure 8. It would involve supplying water to Alcona North from the proposed 9 th Line trunk watermain from the W
TP to the Alcona Reservoir. This would require a new in-line Zone 2 BPS and a new in-line Zone 3 BPS.
For Alcona South, water would be supplied from an expanded BPS and expanded reservoir at the Lefroy reservoir site via 300 mm diameter trunk watermains on 20
th Sideroad and 6 th Line. Similarly to Alternative 1, the water services for the properties in the small area in Alcona South that is at higher elevations would require individual booster pumps to provide the required minimum pressures.

For both alternatives, construction of the third cell of the Alcona reservoir will be needed to provide the required equalization and fire protection storage for the planned growth.
Both water servicing alternatives take into consideration the planned upgrade of the intersection of 20th
Sideroad and Innisfil Beach Road.
Improvements to the available fire flows in Alcona can be addressed by looping watermains where dead ends exist. Three locations have been identified where looping of the watermains could be implemented and would benefit the flow of water in the distribution system:
Ralph Street and Wallace Avenue, via Brock Street
Buchanan Street to 9 th Line Park Road to Florence Road
As residential and commercial developments proceed and intensification occurs, the capacity of the local water distribution system will need to be reviewed to determine if replacement of watermains with larger diameter watermains will be required to convey the required fire flows.
9.1.4Assessm
ent of Alternative Solutions
The comparative assessment of Alternatives 1 and 2 for the water servicing of Alcona’s growth is presented in Table 13. In summary, Alternative 1 has the advantage of requiring less capital infrastructure, which results in lower project costs. The proposed infrastructure maximizes the number of benefitting users/service areas. This specifically refers to the proposed Alcona Reservoir BPS, which will supply water to Alcona’s growth areas and the Town Campus, and could supply water to Innisfil Heights and Stroud. The lesser extent of infrastructure also minimizes the potential social and environmental impacts of the construction projects and the long term operational implications.
9.1.5Recom

In summary, the recommended water servicing solutions for Alcona and the Town Campus, as shown on Figure 7, are:
New 600 mm diameter trunk watermain from the Lakeshore WTP to the Alcona Reservoir via the
25 th Sideroad, 9 th Line, 20 th Sideroad and Innisfil Beach Road. Addition of the third cell at the Alcona Reservoir. Upgrades to the Zone 2 BPS to supply Alcona North in Pressure Zone 2. The extent of the upgrades will be confirmed during design. New in-line Zone 3 BPS in Alcona North. New BPS at the Alcona Reservoir site to supply Alcona South and the Town Campus.

There are no documented issues with the existing private individual and communal water supply systems in the Sandy Cove service area. The existing Sandy Cove Acres retirement community has an adequate private groundwater system. Properties facing on 25 th Sideroad have the opportunity to connect to the new municipal watermain and some connections have been made.
Innisfil Master Servicing Plan Update Final Draft Report
Page 54 July 13, 2018
As Sandy Cove is a designated Urban Settlement Area, it is intended that growth be accommodated by full municipal services. Accordingly, proposed developments in Sandy Cove will be serviced by connections to the Lakeshore system’s trunk watermain on 25 th Sideroad.
9.2.2Recom

No alternative solutions were considered because:
The existing 25 th Sideroad trunk watermain was designed and built with sufficient capacity to meet the water demands of all existing properties and proposed developments within the Sandy Cove service area as well as the Big Bay Point area. Future connections to the 25 th Sideroad watermain system are possible. W
atermains are proposed in Sandy Cove as required to serve the proposed developments. Connection stubs have been installed along the 25
th Sideroad trunk watermain for future watermains for the future residential developments in Sandy Cove.
The recommended municipal water servicing projects for Sandy Cove, as shown on Figure 9 are:
300 mm diameter watermain on Lockhart west of 25th Sideroad to the limits of the settlement area

No alternative solutions were considered because the existing 25th Sideroad trunk watermain and the
Friday Harbour internal water system were designed with sufficient capacity to meet the water demands of the proposed Friday Harbour Resort and the existing properties in the Big Bay Point area. Future connections to the municipal water distribution system are possible if there is a need and desire to do so.
If in the future the residents of Big Bay Point wish to abandon their private water supplies and connect to the Lakeshore water system, two connection points are possible:
At Big Bay Point Road and Friday Drive. A 300 mm diameter watermain would be required to connect the north east area of Big Bay Point. South of Big Bay Point, to the municipal watermain at Riva Avenue in Friday Harbour Resort.
As per the current land designations in the Official Plan, these watermains would be local improvement projects (not in the 2018 DC).

9.5Stroud
9.5.1W
ater System Description
Stroud is serviced by a municipal groundwater system. The Stroud water system has a rated capacity of 2,622 m
3/day as per the DWW
P. It is supplied by three groundwater wells with a combined permitted capacity of 2,711 m
3/day. Well No. 3 is the main supply well, permitted to supply up to 1,637 m
3/day. W
ells Nos. 1 and 2 are stand-by wells with permitted capacities of 677 m3/day and 397 m
3/day
Innisfil Master Servicing Plan Update Final Draft Report

respectively. Water treatment consists of green sand filtration for iron and manganese removal, and
chlorine disinfection. Treated water is stored in a 1,263 m3 reservoir, and pumped into the distribution
system by a pumping station with a firm capacity of 51 L/s. There is one pressure zone in Stroud. Figure 10 illustrates the Stroud water system.
9.5.2W
ater System Condition
During well and pump maintenance of the two lower capacity wells in 2016-2017, it was found that:
Well No. 1’s performance appeared to have deteriorated over time and the casing had an obstruction
that prevented the well’s rehabilitation. The well may have to be decommissioned. W
ell No. 2’s performance also appeared to have deteriorated and the well casing was corroded. There was significant mineral precipitate and biofilm. The well was rehabilitated and new pumping equipment was installed but the initial well performance was not restored.
Due to these issues, InnServices is not using Wells Nos. 1 and 2 and relies almost entirely on W
ell No. 3. InnServices is evaluating the groundwater supply to determine the appropriate remedial measures.
The greensand filter system is working well, and there are no longer any iron issues in the distribution system. All greensand filter valves were recently replaced; the valve seals deteriorated likely due to the high chlorine concentration from the use of chlorine for pre-oxidation.
High lift pumps 2 and 3 were replaced in 2016. THMs have started to form in the reservoir. This may require some treatment modifications in the future. The diesel generator set is 20 years old and will need to be replaced over time. The filter backwash holding tank building requires some upgrades as the brick is starting to deteriorate and the roof is leaking at the skylight.
Many watermains throughout Stroud are old cast iron pipe and will need to be replaced over time.
9.5.3W
ater System Needs
As summarized in Table 14, the Stroud water system can supply the existing and projected water demands with W
ell No. 1 only, however the system does not have the required stand-by supply capacity with the reduced capacity of W
ells Nos. 1 and 2.
The Stroud system has sufficient water treatment capacity to meet the projected future needs associated with the community’s limited growth to the year 2031.

The Stroud facility was not designed to supply the fire protection flows that are suggested by FUS for higher density residential developments. The fire protection capacity is adequate for low density residential, as currently exists. Since the density of future residential developments will continue to be limited by the absence of sewers (septic systems require large lots and large separation distances between homes), the FUS criteria of 100 L/s is considered too conservative for Stroud.
Overall, the existing Stroud water system needs a reliable water supply for its existing residents and to accommodate the planned growth.
9.5.4Description of Alternative Solutions
The following alternative solutions were considered for the replacement or upgrade of the Stroud water system:
Alt. 1: Rehabilitate the wells or drill a new stand-by well, and continue to use the existing groundwater system.
Alt. 2: Connect Stroud to the Barrie water system.
Alt. 3: Connect Stroud to the Lakeshore water system.
Based on the Well Nos. 1 and 2 maintenance reports by IW
S, a licensed well specialist, the existing wells cannot be rehabilitated to yield a sufficient water supply to be considered stand-by wells to W
ell No. 3. Therefore, Alternative 1 would require one or more new wells to be built, capable of supplying the projected MDD. The new stand-by wells should be located on the site of the Stroud water system to minimize infrastructure costs.
Innisfil Master Servicing Plan Update Final Draft Report
Page 60 July 13, 2018
Alternative 2, connection to the Barrie water distribution system, was discussed with City of Barrie staff. They indicated Barrie could consider extending a watermain to their south boundary of Lockhart Road once they have completed their planned extensions of watermains on Mapleview Drive and Yonge Street that will supply local distribution mains. The distance from the Stroud water reservoir to the City of Barrie limits at Lockhart Road and Yonge Street is 1.5 km. However, their preliminary review of available capacity will not be completed until their water infrastructure models are updated for their Master Plan update. The City also indicated their need to assess the compatibility of this external servicing with the City’s growth management plan. The timing of a response from the City of Barrie is not expected until mid to late 2018. Servicing costs and terms of an agreement with the City of Barrie for the supply of water, which would be mainly determined by the City of Barrie, are therefore unknown.
Alternative 3, connection to the Lakeshore water system, would involve a new 3.6 km long 200 mm diameter watermain on Yonge Street, connecting the proposed trunk watermain on Innisfil Beach Road to the Stroud water reservoir. The existing Stroud water reservoir and high lift pumps would be maintained. The existing wells and water treatment system would either be entirely decommissioned or one well and the chlorination system would be maintained as an emergency supply.
9.5.5Assessm
ent of Alternative Solutions
Table 15 presents a comparative assessment of the Stroud water servicing alternative solutions. Alternative 3, connecting to the Lakeshore water system, presents the advantage of a reliable water supply and consistent and high water quality obtained from a state-of-the art membrane filtration W
TP. The disadvantages however reside in the project cost and the timeframe required for implementation, which is contingent on the construction and commissioning of the watermain on Innisfil Beach Road and associated BPS.
9.5.6Recom
mended W
ater Servicing
The preferred water servicing solution for Stroud is to abandon the existing groundwater system and connect to the Lakeshore water system once the Innisfil Beach Road watermain and BPS are constructed. It will involve:
New 200 mm diameter watermain on Yonge Street from Innisfil Beach Road to the Stroud reservoir.
In the interim, a water supply investigation should be completed to assess the feasibility of constructing a new stand-by well on the Stroud water system site to provide system reliability to existing residents and enable development projects to proceed.

Table 15: Comparative Assessment of Stroud Water Alternatives
Criteria Alternative 1 – Refurbish Wells Alternative 2 – Connect to Barrie Water System
Alternative 3 – Connect to Lakeshore Water System
Impacts on Servicing
New well(s) must be built to provide the required firm capacity and meet the existing and future water demands. A groundwater supply investigation and testing program is required to confirm the feasibility of an additional well on site. Upgraded water supply required for servicing new developments. If adequate groundwater supply is found, new well(s) could be implemented within one year.
A connection to Barrie could provide the required water supply capacity if Barrie confirms feasibility. Timing is contingent on reaching a water supply agreement with the City of Barrie.Therefore, timing to a connection that would enable new developments to proceed is unknown.
A connection to the Lakeshore water system could provide the required water supply capacity to meet the existing and future demands. Upgraded water supply required for servicing new developments. Timing of connection requires construction of Innisfil Beach Rd watermain and BPS, approximately 2 years.
Technical and Operational Considerations
Operation and maintenance of the water treatment system for iron and manganese removal remains, in addition to the pumping system and storage tank, which would remain. Upgrades anticipated to be required to address THM formation from chlorination of the groundwater organic content.
Operation and maintenance of a new watermain, in addition to the Stroud pumping system and storage tank, which would remain. Less O&M than for Alternative 1. No source water protection restrictions.

Wastewater servicing needs in Innisfil North (Alcona, Big Bay Point, Leonards Beach, and Sandy Cove)
and the recommended servicing solutions are presented in this chapter.
10.1Alcona
10.1.1W
astewater Servicing Needs
The anticipated growth and associated increase in wastewater flows will bring some of the Lakeshore wastewater system in Alcona over its conveyance capacity.
Due to projected growth in Alcona, Sandy Cove and Big Bay Point, additional pumping capacity and twinning of the forcemains will be required at SPS #3 and SPS #4 by 2031.
Projected increases in wastewater flows resulting from growth and intensification in Alcona and new developments in Innisfil North will exceed the capacity of some sewers near the Alcona lakeshore. Specifically, sewers that are predicted to run at more than 85%
of their capacity are located on:
Leonard Street Crystal Beach Road Lakelands Avenue Adams Road Simcoe Boulevard Cross Street Cedar Grove Avenue Park Road 6th Line just upstream of the W
PCP
Development in the Alcona North growth area will also require a new sanitary sewer on the 9 th line to connect to the existing Lakeshore sewer system in addition to the connection at Spring Street.
10.1.2W
astewater Servicing Solutions
Expansion of SPS #3
The existing capacity of SPS #3 of 446 L/s and its 450 mm diameter forcemain to the Lakeshore WPCP
is insufficient to convey the peak flows from the proposed developments in Sandy Cove and the build-out of the Friday Harbour Resort, which are projected to reach approximately 584 L/s in 2031 and ultimately up to 672 L/s.
Innisfil Master Servicing Plan Update Final Draft Report
Page 63 July 13, 2018
The SPS facility is located in an established residential area. Expansion of the facility needs to be accommodated on the existing site in order to prevent extensive modifications to the sanitary sewer system upstream of the SPS and to maintain the existing forcemain to the W
PCP. As the site has sufficient area for the expansion of the control building and wet well, alternative locations do not need to be considered and evaluated.
The SPS expansion will involve expanding the control building to accommodate the additional MCCs, expansion of the wet well and replacement of the submersible pumps. It is expected that the main and emergency electrical supply, including the transformer and generator, will need to be replaced with larger units for the larger pumps. A second forcemain will be required to maintain velocities within an acceptable range.
Expansion of SPS #4
SPS #4 and its 400 mm diameter forcemain, must be expanded to convey the estimated wastewater flows for the year 2031. The current firm capacity of 230 L/s needs to be increased to approximately 417 L/s by 2031 and ultimately up to 500 L/s.
SPS#4, located within an established residential area, should be expanded on the existing site to minimize the extent of modifications to the upstream and downstream sanitary sewer system. The existing site is compact however, it has sufficient area to accommodate an expanded wet well and control building. Alternative locations and replacement of the SPS were therefore not considered and evaluated.
The SPS expansion will involve expanding the control building to accommodate the additional MCCs, expansion of the wet well and replacement of the submersible pumps. It is expected that the main and emergency electrical supply, including the transformer and generator, will need to be replaced with larger units for the larger pumps. The forcemain will be twinned to maintain velocities within an acceptable range.

10.2.1W
astewater Servicing Needs
New developments at the Town Campus site, including the new private school and the proposed IHP health hub, will require an increase in the capacity of the existing wastewater collection and pumping system that was designed for the existing Town’s municipal offices and the MURF only.
The Town Campus is identified in Innisfil’s Our Plan Official Plan as an area where future major government and cultural facilities shoud be considered and where related commercial developments may occur. The Town is preparing a master plan for the Town Campus. Accordingly, wastewater servicing needs for this area will increase and a servicing approach is required. For the purpose of this Master Plan Update, a commercial/institutional service area of 50 ha, including the Town Campus, was assumed in order to estimate wastewater servicing needs.
10.2.2W
astewater Servicing Solutions
The existing Town Campus wastewater pumping station (SPS #6) will be upgraded with minor pump modifications to increase its pumping capacity in order to service the proposed health hub, which is scheduled to be constructed in 2019. It only addresses the immediate needs of the Town Campus.
A longer-term servicing solution is to service the Town Campus in conjunction with the servicing plan for the Innisfil Heights economic district, which will involve trunk sewers on Innisfil Beach Road and 6
th Line to the Lakeshore W
PCP. The Innisfil Heights servicing alternatives and the recommended solution are discussed in more detail in Chapter 12.
10.3Sandy Cove
10.3.1W
astewater Servicing Needs
There are no documented issues with the existing private individual septic systems in the Sandy Cove service area.
There may be a need in the future however to extend municipal sanitary servicing to existing properties in Sandy Cove that are currently on private septic systems, in order to minimize the potential for contamination of Lake Simcoe if and when these systems fail.
There is also the need to provide municipal sanitary servicing for the planned residential developments in Sandy Cove.
Innisfil Master Servicing Plan Update Final Draft Report
Page 66 July 13, 2018
10.3.2W
astewater Servicing Solutions
Existing properties can remain on individual septic systems as no issues have been identified. In the future, existing properties could be connected to the Lakeshore wastewater system, as the 25
th Sideroad trunk sewer has been designed with sufficient capacity to convey wastewater flows from these existing properties, and the proposed capacities of the SPS expansions and sewer upgrades in Alcona will be sized for those flows. The sewers to connect to the 25 th Sideroad trunk sewer system will be local improvement projects.
The proposed developments in the Sandy Cove settlement area can be serviced by the Lakeshore wastewater system. The 25 th Sideroad and Lockhart Road trunk sanitary sewers have been sized to convey the projected flows from all the developments in the Sandy Cove settlement area. A new Sandy Cove SPS located at or near Pinegrove Avenue will be required to service lands that cannot be serviced by gravity sewers to 25 th Sideroad or Lockhart Road.
No alternative solutions needed to be considered.

There are no documented issues with the existing private individual septic systems serving the properties in Big Bay Point. As for other unserviced communities on the shoreline, there may be a need in the future to consider extending sanitary servicing to the existing areas in Big Bay Point that are currently on private septic systems, in order to minimize the potential for contamination of Lake Simcoe if the septic systems fail.
Wastewater servicing needs for the Friday Harbour Resort will be met by the Lakeshore wastewater
system that has been extended to Big Bay Point Road, including the recently built Mapleview SPS. Future servicing needs for Friday Harbour Resort’s expansion will require an increase in the pumping capacity of the Mapleview SPS.

10.4.2W
astewater Servicing Solutions
Existing properties in Big Bay Point can remain on individual septic systems as no issues have been identified. In the future, existing properties in the Big Bay Point Shoreline community, north and south of Friday Harbour Resort, could be connected to the Lakeshore wastewater system, as the internal Friday Harbour SPS, the Mapleview SPS and the downstream trunk sewer system have been designed with sufficient capacity to convey wastewater flows from these properties, and the proposed capacities of the SPS expansions and sewer upgrades in Alcona will be sized for those flows.
If and when sewers are required, a Big Bay Point SPS and forcemain will be needed to convey the wastewater flows from the east of Friday Harbour to the existing sewer system at Friday Drive. This project will be a local improvement project.
No alternative solutions needed to be considered.
10.4.3Recom

10.6Stroud
10.6.1W
astewater Servicing Needs
There are no documented issues with the existing private individual septic systems serving the properties in Stroud. There is also limited growth planned for Stroud. However, if this current situation changes, municipal servicing should be considered.
10.6.2W
astewater Servicing Solutions
Existing properties in Stroud can remain on private septic systems as no issues have been identified. The proposed new developments in Stroud are proposed to be serviced with septic systems in the absence of a municipal sewer system.
In the future, if it is determined that a municipal sanitary sewer system should be constructed to service all or parts of Stroud, it could be connected to the Lakeshore wastewater system via a SPS and forcemain connecting to the proposed Innisfil Beach Road sewer. Capacity in the proposed sewer system to the W
PCP for a future Stroud connection has been accounted for. However, there may be limitations at the Lakeshore W
PCP; the availability of treatment capacity will need to be reviewed at that time and will be contingent on actual and allocated flows and treatment performance.

Innisfil Central includes the Settlement Employment Area of Innisfil Heights and the Hamlet of Churchill. Innisfil Heights and Churchill’s water systems, their current and future servicing needs and the recommended servicing solutions are described in this chapter.
11.1Innisfil Heights
11.1.1Innisfil Heights W
ater System Description
The Innisfil Heights water system, as shown on Figure 12, is supplied by two groundwater wells drilled into a confined aquifer. W
ell No. 2 is equipped with a 34 L/s pump; Well No. 3 has a 36 L/s pump. The
wells have a combined permitted capacity of 3,110 m3/day. Raw water is chlorinated and pumped
through the distribution system to a 2,200 m3 reservoir that provides storage for fire protection, flow
equalization and emergency. Drinking water is pumped from the reservoir into the distribution system by a high lift pumps with a firm capacity of 160 L/s. The Innisfil Heights reservoir and BPS facility, located on Commerce Park Drive, was designed for the ultimate planned expansion of the Innisfil Heights economic district. The reservoir can be expanded to a volume of 8,800 m
3and high lift pumps with a firm capacity of 400 L/s can be accommodated in the BPS.
The Innisfil Heights water system supplies water to the existing economic district and the Innisbrook residential subdivision east of Highway 400. The water distribution system extends to the OnRoute service station and to OLG Slots at Georgian Downs via two watermain highway crossings, one at the 7 th Line and one north of Innisfil Beach Road to serve Georgian Downs.
The majority of the Innisfil Heights area is located in a single pressure zone. Existing homes in the Innisbrook subdivision that are at elevations below 285 m have individual pressure reducing valves.
11.1.2W
ater Servicing Needs
With the construction of the Innisfil Heights water reservoir and BPS in 2014, the existing water system
meets the existing capacity needs. Watermains have been replaced in the past three years to address
limitations in the water distribution system to convey adequate fire flows.
The Innisfil Heights reservoir and BPS facility was designed for future expansions to meet the projected water demands in the Innisfil Heights water distribution system, as per OPA1.
The issue of concern at Innisfil Heights, as shown in Table 16, is that the existing Innisfil Heights groundwater supply has insufficient capacity to meet the projected future water servicing needs as the employment lands expand to their ultimate area.

11.1.3Description of Alternative Solutions
The following alternative solutions for increasing the water supply capacity for the Innisfil Heights water system were considered:
Alt. 1: Increase the capacity of the groundwater supply system.
Alt. 2: Supply water from the City of Barrie water system.
Alt. 3: Supply water from the Lakeshore water system.
Alternative 1 is not a viable solution. It has been confirmed by performance testing of the wells (Golder, January 2013) and an aquifer assessment study (Golder, May 2013) that increasing the supply capacity of the groundwater wells is not a feasible solution. The regional aquifer in which the wells are drilled cannot support the ultimate projected water flows for the expanded economic district without unacceptable declines in the water table, and no other aquifer appears to be available that could supply the projected water needs. Therefore, this alternative was not considered further.
The feasibility of supplying water from the City of Barrie water distribution system, Alternative 2, was discussed with City of Barrie staff on January 8, 2018. The City’s preliminary review of available capacity will not be completed until their water infrastructure models are updated for their Master Plan update. The City would also need to assess the compatibility of a water supply to Innisfil with the City’s growth management plan. The timing of a response from the City of Barrie is not expected until mid to late 2018. The feasibility, costs, and terms of an agreement for external servicing with the City of Barrie remain unknown and would be mainly determined by the City of Barrie.
Innisfil Master Servicing Plan Update Final Draft Report
Page 72 July 13, 2018
The supply of water from the Lakeshore water system, Alternative 3, could meet the needs of the economic district expansion. The Innisfil Heights reservoir and BPS was designed for a future connection to the Lakeshore water system. Two options were considered for Alternative 3:
Option A: Twin water transmission mains on Innisfil Beach Road.
Option B: One water transmission main on Innisfil Beach Road and one water transmission main on Yonge Street and 6 th Line.
Alternative 3A is shown on Figure 13. The water transmission main on Innisfil Beach Road would be constructed as part of the planned road reconstruction by the County of Simcoe in 2019 - 2021, and would meet other water servicing needs, including an alternate supply to Stroud, and an improved water supply to the Town Campus and associated developments at Yonge Street.
The potential Campus Node on 6 th Line would be serviced via a connecting watermain on Yonge Street. This Yonge Street watermain between Innisfil Beach Road and 6
th Line would enable a future watermain looping with the 6 th Line watermains in Alcona and a connection with the 6 th Line watermains in Innisfil Heights. Both connections would require pressure reducing valves due to the differences in pressures. In an emergency, the Innisfil Heights water distribution system could discharge through a PRV into a 6
th
Line watermain; similarly, the 6 th Line watermain could discharge through a PRV into Alcona Pressure Zone 1.
The Innisfil Beach Road transmission main to the Innisfil Heights reservoir would be twinned, in two construction phases, in order to provide redundancy for supply reliability, provide better operating conditions and utilization of the pipes; and defer costs until the water supply capacity is needed.
The construction of a BPS at the Alcona Reservoir site is required to pump water from Alcona to Innisfil Heights. The construction of the additional trunk watermain between the Lakeshore W
TP and the Alcona Reservoir is also required to supplement the supply capacity to the Alcona Reservoir site.
The following twinning sub-options were considered for the configuration of the water transmission main on Innisfil Beach Road, considering all potential water demands along its route, as follows:
Twinning Sub-option 1: Single 7.8 km (from Alcona to Innisfil Heights) 400 mm diameter watermain installed at the onset; the second 7.8 km watermain installed when needed, and sized based on updated water demands.
Twinning Sub-option 2: At the onset, twin 2.5 km, 400 mm diameter watermains from Alcona to Yonge Street, and single 400 mm diameter watermain from Yonge Street to Innisfil Heights. The second watermain from Yonge Street to Innisfil Heights would be installed when needed and sized based on updated water demands.

Innisfil Master Servicing Plan Update Final Draft Report

Alternative 3A with Twinning Sub-option 2, in which the watermain is twinned up to Yonge Street in the first phase, is preferred because it reduces disruption on Innisfil Beach Road by minimizing the number of construction projects, improves supply redundancy at Yonge Street, and benefits more significantly from cost sharing with the County‘s Innisfil Beach Road reconstruction project.
Alternative 3B is shown on Figure 14 overleaf. This option was developed to provide two water supply lines from the Lakeshore water system to the Innisfil Heights economic district to achieve some redundancy and improved reliability, using two separate routes, such that each route could have water servicing in the future. In Option B, one water supply main would be on Innisfil Beach Road, the other would be on 6 th Line.
A 6 th Line water supply main would provide water to the expansion area of the Innisfil Heights economic district, i.e., south of the 7 th Line, in a separate pressure zone from the one supplied by the existing Innisfil Heights BPS north of the 7 th Line. Therefore, Innisfil Heights would have two pressure zones. Pressure reducing valves on the trunk watermains in Innisfil Heights would enable connections between the two pressure zones in the event of a fire or of a break in the Innisfil Beach Road or the 6
th Line water supplies.
Water pumped from the new Alcona Reservoir BPS would be conveyed via twin watermains on Innisfil
Beach Road to Yonge Street. In a first phase corresponding with the development of the existing Innisfil Heights economic district, the watermain would be extended on Innisfil Beach Road to the Innisfil Heights Reservoir. In a second phase corresponding with the expansion of the economic district, watermains would be installed on Yonge Street and 6 th Line to a new reservoir and BPS on 6 th Line west of the 10 th
Sideroad. For this future phase, twin watermains, placed in operation in a phased manner, are preferred to ensure reasonable pipe velocities as the water demands gradually increase.
This 6 th Line BPS would provide the required pessures for the distribution system in the Innisfil Heights economic district between the 7 th Line and the 5 th Line. The 6 th Line Reservoir would provide equalization and emergency storage. Fire storage would continue to be provided in the Innisfil Heights Reservoir, so as not to duplicate this existing capacity.
With Option B, the planned Innisfil Heights Reservoir and BPS expansions would be limited to the
planned Phase 2 expansion as required to meet the demands in the Innisfil Heights economic district north of the 7 th Line.
Water pumped from the Alcona Reservoir BPs to a 6 th Line Reservoir could also fill a Campus Node
reservoir sized for the Campus Node and other local developments.
It is noted that the 2012 MSP considered an alternate approach to achieving a reliable water supply to Innisfil Heights. It involved an Innisfil Beach Road supply, pumped from a BPS at the Alcona Reservoir site, and a 6 th Line supply, pumped from the Lefroy BPS, both of which discharged to a new reservoir in Innisfil Heights that was to be located near the 7 th Line and 5 th Sideroad.

Although installing twin watermains on Innisfil Beach Road to Innisfil Heights in two phases to match growth of the economic district (Alternative 3A) is the lowest cost solution to providing a reliable water supply, in the longer term, the future extension of water servicing to the 6 th Line (Alternative 3B) may become necessary to service developments in the 6
th Line corridor such as the potential Campus Node. Alternative 3B also benefits from the County‘s Innisfil Beach Road reconstruction project starting in 2019, that will minimize construction costs and disruption. Therefore, in view of the long-term potential for growth in the Innisfil Beach Road corridor as well as in the 6
th Line corridor, Alternative 3B is considered the preferred long-term water servicing approach.
11.1.5Recom
mended W
ater Supply Solution
The recommended solution to meet the water supply needs of the Innisfil Heights economic district is to connect to the Lakeshore water system via a water transmission main on Innisfil Beach Road in a first phase, and in the future, via a water transmission main on 6 th Line, as shown on Figure 14.
The recommended water supply infrastructure for the first phase of expansion of the Innisfil Heights economic district will consist of:
Twin 400 mm diameter water transmission main from the Alcona Reservoir site to Yonge Street. Single 400 mm diameter water transmission main from Yonge Street to the Innisfil Heights Reservoir.300 mm diameter watermain on Yonge Street to south limit of Town Campus site.400 mm diameter watermain on 5 th Sideroad from 9 th Line to 7 th Line. Expansion of the Innisfil Heights Reservoir (Phase 2) and replacement of the pumps at the Innisfil Heights BPS (Phase 2) New BPS at the Alcona Reservoir site. This facility will have multiple functions, including pumping to Alcona South, as described in Section 9.1.5.
It is recommended that the Innisfil Heights groundwater wells be maintained as a stand-by water supply until the future second Lakeshore supply watermain is implemented. The wells also have capacity (up to a MDD of 3,110 m
3/day) to support a limited amount of growth/redevelopment in the economic district.
To service the future expansion of the Innisfil Heights economic district (OPA 1 lands), the following water infrastructure is anticipated to be required, with watermain, BPS and reservoir sizing to be confirmed to suit development plans:
Twin 300 mm diameter watermains on Yonge Street and 6 th Line. New 6 th Line Reservoir and BPS (in phases). 500 mm diameter watermain on 6 th Line from the 6 th Line BPS to Innisfil Heights. 400 mm diameter watermains on extension of Commerce Park Drive from the 7 th Line to the 5 th Line. 400 mm diameter watermain crossing of Highway 400 at the 6 th Line. 300 mm diameter watermain on Bowman Street to increase available fire flows.

The implementation of the Innisfil Heights water servicing plan will also require the construction of the new trunk watermain between the Lakeshore W
TP and the Alcona reservoir that is discussed in Section 9.1.5.
11.1.6Cam

ater Servicing
The Innisfil Beach Road trunk watermain and the new booster pumping station at the Alcona Reservoir site will be capable of supplying water in the future to the 6 th Line, including to a local reservoir and BPS that would serve facilities at the Campus Node, as shown on Figure 14.
Due to the rolling topography on 6 th Line, local or individual BPS and PRVs will be required to maintain pressures within acceptable range. The proposed 6 th Line BPS should be designed to provide distribution pressures in Innisfil Heights as well as to the area between Highway 400 and 10
th Sideroad.
In the future, a 6 th Line water distribution main east of Yonge Street could be connected to Alcona’s water distribution system with a pressure reducing valve as Alcona operates in lower pressure zones.
11.2Churchill
11.2.1Churchill W
ater System Description
The Churchill water system is supplied by three groundwater wells with a combined permitted capacity of 743 m
3/day. Raw water is chlorinated and pumped to a 95 m3 capacity reservoir. Treated water is
pumped into the distribution network by a BPS with a firm capacity of 1,296 m3/day. The system is
illustrated on Figure 15.
A new BPS and treated water reservoir are currently in construction to replace the existing BPS and reservoir. The new facility will provide sufficient capacity for growth, up to the projected population to the year 2031, and will improve fire protection, to provide a fire flow of 100 L/s for 2 hours. The new reservoir will have a volume of 1,100 m
3and the BPS will have a firm capacity of 109 L/s.
Issues with THMs have been noted at the dead ends of the water distribution system. Innisfil operation staff will consider adding flushing stations.
11.2.2W

12.1Innisfil Heights
Innisfil Heights’s economic district and residential community rely on individual septic systems for wastewater disposal.
As a Strategic Settlement Employment Area, the Innisfil Heights economic district is planned to be expanded. The first phase consists of growth within the existing settlement area to provide approximately 325 ha of commercial/industrial land. In the future, 320 ha of employment lands will be added, for a total of 645 ha. This future expansion, as per OPA1, will extend the south boundary of the economic district from the 7 th Line south to the 5 th Line on both sides of Highway 400, and will include two parcels of land at the northern limit of the economic district. The future expansion of the economic district is considered to occur post 2031.
12.1.1W
astewater System
Needs
There are no documented issues with the existing private individual septic systems that serve Innisfil Heights.
However, the planned development of the Innisfil Heights economic district would benefit from a municipal sanitary sewer system to maximize the land’s development potential.
12.1.2Description of Alternative Solutions
The following wastewater servicing alternatives were considered to support the planned expansion of the Innisfil Heights economic district:
Alt. 1. Establish a sanitary sewer system discharging to one or more communal subsurface disposal systems.Alt. 2. Establish a sanitary sewer system connected to the City of Barrie municipal wastewater system.Alt. 3. Service by private individual septic systems. Alt. 4. Establish a sanitary sewer system connected to the Lakeshore wastewater system via the 6 th Line. Alt. 5. Establish a sanitary sewer system connected to the Lakeshore wastewater system via Innisfil Beach Road. Alt. 6. Establish a sanitary sewer system connected to the Lakeshore wastewater system via Innisfil Beach Road for the first phase of development, and via the 6 th Line for the second phase.
Alternatives 1 and 3 were screened out for the following reasons:
Innisfil Master Servicing Plan Update Final Draft Report
Page 82 July 13, 2018
Alternative 1, communal subsurface disposal systems, was not considered further because it is not considered a feasible approach. Communal subsurface disposal systems for the projected wastewater flows would be extremely large, exceeding the size of large communal beds designed and built in Ontario. The areas required for such systems would reduce the land area available for development. Further, it would be very difficult, without wastewater treatment, to meet the MOECC Reasonable Use requirements for the protection of groundwater quality.
Alternative 3, continuing to service with individual tile beds, was not considered further as it would limit the type of commercial and industrial uses to dry or low wastewater generation facilities. This alternative would not satisfy the Town of Innisfil’s intent to provide a fully serviced industrial park.
Alternative 2, connecting to the City of Barrie sanitary sewer system, was discussed with the City of Barrie on January 8, 2018. City staff indicated the Barrie system could likely physically accommodate the wastewater flows from Innisfil Heights, however their preliminary review of available capacity will not be completed until their sanitary infrastructure models are updated for their Master Plan update. The City also indicated their need to assess the compatibility of this external servicing with the City’s growth management plan. The timing of a response from the City of Barrie is not expected until mid to late 2018. Available capacity, servicing costs, and terms of an agreement with the City of Barrie for current and future capacity and servicing costs were therefore unknown and would be mainly determined by the City of Barrie. This approach for wastewater servicing could not be considered in detail in the absence of further information.
Alternatives 4, 5 and 6 were considered in more detail. Two routes for connecting Innisfil Heights to the Lakeshore wastewater system were considered: via the 6 th Line (Alternative 4); and via Innisfil Beach Road (Alternative 5). Alternative 6 was added following receipt of input from the County of Simcoe. It involves using the Innisfil Beach Road route for the first phase of the Innisfil Height Economic District expansion (7 th to 9 th Line), and using the 6 th Line route for the second phase of the development (south of 7 th Line). All three alternatives were developed at a preliminary level with due consideration of available grades and modelled with SewerCAD to establish sewer pipe sizing, required pumping station capacity and head, and forcemain sizing.
The wastewater flows for all alternatives included flows from Cookstown to ensure the pipes would have sufficient capacity if the Cookstown Class EA concludes servicing to the Lakeshore wastewater system via 5 th Sideroad to Innisfil Heights is the preferred solution. For Alternative 6, two options were considered:
Alternative 6, Option A: Cookstown flows are directed to the first phase of the Innisfil Heights sanitary sewers to Innisfil Beach Road;Alternative 6 Option B: Cookstown flows are directed to the second phase of the Innisfil Heights sanitary sewers to 6 th Line.
The sewers for all alternatives also included wastewater flows from the potential 42 ha Campus Node.

Alternatives 4, 5 and 6A and 6B are shown on the attached Figures 16, 17, 18 and 19. All figures show, in red, the works that would be necessary to serve the first phase of the economic district expansion to the 7 th Line (year 2031), and in green the works that would be needed to serve the future expansion (OPA 1, post 2031).
12.1.3Assessm
ent of Alternative Solutions
The preliminary comparative assessment Alternatives 4, 5 and 6 is summarized in Table 19. Estimated project costs for each alternative are summarized in Appendix B.
Alternative 6B, which consists of constructing the trunk sanitary sewer system on Innisfil Beach Road for the first phase of the expansion of the Innisfil Heights economic district, and constructing a trunk sewer system on 6 th Line for the future expansion phase, with sufficient capacity for servicing Cookstown, is the preferred solution for the following reasons:
It enables the sanitary servicing to proceed concurrently with the County road reconstruction project starting in 2019, thus minimizing construction costs, and minimizing disruption to Innisfil Beach Road during construction.
It has lowest capital costs in Phase 1, which can facilitate initial growth in the economic district, increase the tax base, and assist in funding subsequent infrastructure projects.
It facilitates the servicing in the short term of the Town Campus, its expansion, and the development of lands in the Yonge Street and Innisfil Beach Road area, which is identified in the Town’s Official Plan and where development projects are anticipated in the very short term.
It aligns with the preliminary preferred water supply solution to Innisfil Heights of a water transmission main in the Innisfil Beach Road corridor, thus achieving efficiencies in planning, design and construction.
The Phase 1 infrastructure meets closely the servicing requirements of the planned first phase expansion of the economic district within the existing Innisfil Heights settlement area boundaries. No additional infrastructure needs to be built in the first phase that cannot be fully cost-recovered through the users of the infrastructure. OPA 1 lands do not need to gain official status so that costs can be recouped for Phase 1.
Servicing the future economic district expansion, which is between the 7th Line and 5 th Line, through
the 6 th Line corridor to the WPCP, reduces infrastructure costs.
The creation of two service corridors will facilitate the development of lands in both corridors, including the potential Campus Node.
A 6 th Line trunk sewer system will provide a lower cost servicing alternative for Cookstown than the more distant Innisfil Beach Road trunk sewer system.

Impacts on Servicing
Servicing of the Town Campus expansion will require a separate sewer line to the 6th Line trunk sewer. Facilitates servicing of the future Campus Node on 6th Line. Proposed sewer on 20 Sideroad facilitates servicing of the Alcona South growth area.
Facilitates servicing of the Town Campus expansion and developments in the Yonge St./IBR area. Servicing the future Campus Node will require a separate sewer line. Proposed sewer on 20 Sideroad facilitates servicing of the Alcona South growth area.
Facilitates servicing of the Town Campus expansion and new developments in the Yonge St./IBR area. Facilitates servicing of the future Campus Node on 6th Line. Doubles the total potential service area. Proposed sewer on 20 Sideroad facilitates servicing of the Alcona South growth area.
Technical and Operational Considerations
Need to install sewers on 5 Sideroad to the south limit of the future economic district expansion in the first phase, although servicing south of 7th Line will not be required in the first phase.Requires the construction of 4 SPS in the first phase, plus up to 3 SPS within Innisfil Heights to service the future economic district expansion. Sanitary forcemain crossing of Highway 400 at 6th Line may be shorter than at IBR and may be partially completed by conventional excavation because of the existing Highway 400 underpass at 6th Line. Trunk sewer construction can be combined with 6th Line road upgrades, planned in the next 5 to 10 years.
Lesser extent of sanitary works on the west side of Highway 400 in the first phase as IBR is central to the existing and expanded economic district. Requires the construction of 4 SPS in the first phase, plus up to 4 SPS within Innisfil Heights to service the future expansion of the economic district. Sanitary forcemain crossing of Highway 400 at IBR will require directional drilling or microtunnelling. Construction of the trunk sewer on IBR can be coordinated with the 2019 County IBR road reconstruction project and concurrently with the installation of the water transmission main. Costs of road reconstruction are picked up by the County.

In the future, if it is determined that a municipal sanitary sewer system should be constructed to service parts or all of Churchill, it could be connected to the Lakeshore wastewater system via a SPS and forcemain connecting to the existing sewer on Killarney Beach Road. The proposed sewer twinning on Killarney Beach Road has sufficient capacity to convey wastewater flows from Churchil to SPS #5, and downstream infrastructure has adequate capacity to convey the flows to the Lakeshore W
PCP. There

13Innisfil South W
ater Servicing
The water servicing requirements for Innisfil South, which consists of the Urban Settlement Area of Lefroy-Belle Ewart, and the Hamlets of Gilford and Fennell’s Corners, and the shoreline communities of Degrassi Point and Big Cedar Point, are described in this chapter.
13.1Lefroy-Belle Ew
art and Big Cedar Point
13.1.1W
ater Servicing Needs
The Lakeshore water distribution system currently only extends into Lefroy-Belle Ewart via a trunk watermain on Maple Road and Belle-Aire Beach Road that was installed in 2016. Connecting streets are not serviced by the municipal water system. Only the most recent subdivisions in Lefroy at Belle Aire Beach Road and 20 th Sideroad are serviced. The majority of Lefroy’s existing properties rely on individual well supplies.
There are no documented issues with the existing private individual wells serving the existing properties in Lefroy and Big Cedar Point. However, the need may arise in the future to provide municipal water servicing to the existing properties on individual wells. It is an objective of the 2017 Official Plan that residential and employment growth in Lefroy be on full municipal services.
In Lefroy Pressure Zone 2, which encompasses the new developments west of the railway line, the existing Lefroy BPS can supply the current phases of development up to approximately 800 new units. Expansion of the facility will be required to supply the remainder of the developments in the BPS’ service area.
13.1.2W
ater Servicing Solutions
Existing properties on Maple Road and Belle-Aire Beach Road in Lefroy-Belle Ewart can be serviced by direct connections to the existing trunk watermains. The connection of other areas of Lefroy-Belle-Ewart that are in Pressure Zone 1 will require extensions of the Lakeshore water distribution system south to Killarney Beach Road and to connecting streets. There are no constraints to these projects: the capacity of the proposed W
TP expansion, reservoirs and trunk watermains provide for the connections of currently unserviced lots in this area to the Lakeshore water system. Connection projects can be implemented as local improvement projects.
Water servicing in the area of Lefroy-Belle-Ewart that is within Pressure Zone 2 will be provided by the
planned expansion of the Lefroy BPS (pump replacement) and the extension of internal watermains, up to an equivalent population of approximately 3,900.
Innisfil Master Servicing Plan Update Final Draft Report
Page 93 July 13, 2018
13.1.3Recom
mended W
ater Servicing
The recommended municipal infrastructure in Lefroy is to extend the water distribution system in Lefroy Pressure Zone 2 to Killarney Beach Road, and to increase the Lefroy BPS capacity to meet the water demands of the development plans, as shown on Figure 20. In summary, the recommended projects are:Replacement of the pumps in the Lefroy BPS to increase capacity.
New 400 mm diameter watermain on Killarney Beach Rd., with PRV to connect to Pressure Zone 1. New 400 mm diameter watermain on Church Drive to connect the existing LSAMI P2 watermain to Killarney Beach Road.
Expansion of the Lefroy Reservoir is not expected to be required to service the development plans in the Lefroy Secondary Plan area. Lefroy Reservoir expansion will be needed in the future as water demands increase from connections of existing properties in Lefroy and Innisfil South to the lakeshore water distribution system.
13.2Degrassi Point and Gilford
13.2.1W
ater Servicing Needs
Most of Gilford is serviced by municipal watermains that are supplied by the Lakeshore water system via the water transmission main to Bradford. Gilford has an established network of water distribution mains with hydrants that was originally supplied by a municipal groundwater system. However, the water transmission main to BW
G was not designed to supply fire flows. In the event of a fire in Gilford, fire flows drawn from the water transmission main would reduce the available supply to meet the other water demands in Cookstown and BW
G.
The properties in Degrassi Point rely on individual water supplies. There are no documented issues with these systems. However, the need may arise in the future to provide municipal water servicing to the existing properties on individual wells.
13.2.2W
ater Servicing Solutions
In the absence of any issues with the existing private water supplies, no alternative water servicing solutions were specifically considered for the Degrassi Point shoreline.

The following alternative solutions were considered for the provision of an adequate supply for fire protection in Gilford:
Alt. 1: Extension of the Lakeshore water distribution system south to Gilford.
Alt. 2: New water storage tank near or in Gilford, supplied from the Alcona to Bradford water transmission main.
Alt. 3: Continue to rely on the water transmission main to supply fire flows to Gilford.Alternative 1 would involve extending a 300 mm diameter watermain south on Pine Avenue to and on 3
rd Line and south along the shoreline to connect to the existing water distribution system in Gilford. However, the network of roads on the shoreline between 3 rd Line and 2 nd Line is not continuous, therefore easements would need to be obtained for the construction of this watermain.
Alternative 2 would involve the construction of an elevated tank or standpipe with a minimum volume of 572 m
3, which would be sufficient to supply a fire flow of 38 L/s for 2 hours.
Alternative 3 is the status quo, whereas fire flows are supplied from the connection to the water transmission main. This may result in a short term decrease in the flow supplied to Cookstown and Bradford.
A comparative assessment of these alternatives is presented in Table 20.
13.2.3Recom
mended W
ater Servicing
The recommended water servicing for Gilford and Degrassi Point is to maintain the status quo, Alternative 3, until the Lakeshore water system is extended south through Lefroy and until there is an expressed need or desire by the residents of Degrassi Point to connect to the municipal water system. The future extension of watermains to Degrassi Point would be a local improvement project.
13.3Fennell’s Corners
13.3.1W
ater System Needs
The Goldcrest water system, which is supplied from the Alcona to Bradford water transmission main, is adequate for the existing and future water demands and pressure requirements at Fennell’s Corners.
As noted in Table 21, the existing water storage tank and fire pump can meet the minimum Town fire protection standard of 38 L/s for 2 hours. The facility was not designed to supply fire protection flows that are suggested by FUS for higher density residential developments. As Fennell’s Corners is a low density residential community with large lots, the current fire protection capacity is considered adequate. However, there is no back-up fire pump. Although the Alcona to Bradford water transmission main that supplies water to the Goldcrest system was not designed to provide fire flows, it provides additional security of supply in the event of a large fire that exceeds the Goldcrest water storage volume.

astewater Servicing
The wastewater servicing requirements, servicing solutions and recommendations, for Innisfil South (Lefroy-Belle Ewart, Gilford, Fennell’s Corners, Degrassi Point and Big Cedar Point) are described in this chapter.
14.1Lefroy-Belle-Ew
art and Big Cedar Point
14.1.1W
astewater System
Needs
Most of Big Cedar Point and Lefroy-Belle Ewart is serviced by the Lakeshore wastewater system. All proposed developments in Lefroy are planned to be serviced by connections to the Lakeshore wastewater system. There are no documented issues with existing individual septic systems in Lefroy. If the need to abandon septic systems arise, connections to the municipal system are possible.
The existing SPS #2 at the eastern end of 6th Line in Big Cedar Point requires minor maintenance
including new roof shingles, parging of concrete surfaces in the wet well, and replacement of deteriorating piping and valves in the wet well. This work will not be required if the SPS is decommissioned as part of the new SPS #2 project.
SPS #5 has adequate capacity for the projected wastewater flows. Refurbishing at SPS #5 is required however: the piping and valves in the wet well are deteriorating and need to be replaced.
14.1.2W
astewater Servicing Solutions
No alternative solutions needed to be considered for wastewater servicing in Lefroy and Big Cedar Point as the Lakeshore wastewater system can be extended as required to meet the needs of the existing properties and proposed developments.

The recommended wastewater infrastructure in Lefroy to provide the required conveyance capacity is as follows:
New 300 mm diameter sewer on Killarney Beach Road to increase the capacity of the existing sewer to convey flows from proposed developments to SPS #5.

14.2Gilford and Degrassi Point
14.2.1W
astewater System
Needs
The Lakeshore wastewater system does not extend south of Killarney Beach Road. Degrassi Point and Gilford are serviced by private individual septic systems. There are no documented issues with the existing septic systems.
As for other unserviced communities on the shoreline, there may be a need in the future to consider extending sanitary servicing to the existing properties in Degrassi Point and Gilford in order to minimize the potential for contamination of Lake Simcoe if septic systems fail.
Lefroy Harbour Resort in Degrassi Point is planning an expansion, which would require a connection to the Lakeshore wastewater system via a private lift station.
14.2.2W
astewater Servicing Solutions
Alternative routes for a future extension of the Lakeshore wastewater system to Degrassi Point and Gilford were considered, as shown on Figure 21.
Alt. 1: New SPS in Gilford (G2 SPS) with forcemain to new SPS at 2 nd Line (G1 SPS). G1 SPS forcemain on 20 Sideroad to Killarney Beach Road. New Degrassi Point SPS (DP SPS) at 3 rd Line with forcemain to the Lefroy sewer at Pine Street.
Alt. 2: New SPS in Gilford (G2 SPS) with forcemain to new SPS at 2 nd Line (G1 SPS). G1 SPS forcemain along the shoreline to new Degrassi Point SPS (DP SPS) at 3 rd Line, with forcemain to the Lefroy sewer at Pine Street.
Both alternatives involve three new sewage pumping stations. With Alternative 1, the forcemain from
Degrassi Point SPS #2 at 2 nd Line would take a longer route to the 20 Sideroad. This route would avoid constructing a forcemain on the shoreline of Degrassi Point where there are no continuous municipal roads and through the wetland between Limerick Road and Innisfree Place. Alternative 2 would be the more direct route that would require obtaining easements and crossing the wetland. The route for Alternative 2 is also the route for a future watermain if the Lakeshore water system is extended to Gilford.
With either alternative route, the new Degrassi Point SPS would be designed to accommodate the flows
from Lefroy Harbour Resort, and its forcemain would be constructed within municipal right of ways.
Table 22 summarizes the comparative assessment of the two alternative routes.

Cookstown is connected to the Lakeshore water system via a connection to the Alcona to Bradford water transmission main. The existing water distribution system is illustrated on Figure 22 overleaf.
The water supply capacity allocated to Cookstown in the original design of the water transmission main (1,182 m
3/day) is adequate for the existing community and some of the currently planned growth in Cookstown, as shown in Table 23. A small increase in the allocated capacity to Cookstown will be required when the water transmission main is twinned, in order to meet the projected maximum day water demands.
The storage volume in the Cookstown standpipes is sufficient for the current and projected water demands to the year 2031.

The east standpipe is in relatively good condition. The older west standpipe had leaks when a riser was pulled off the side wall by ice, and the communication antennae welded directly to the side wall of the standpipe may over time impact the integrity of these sections. The exterior paint is peeling off and rust stains are noticeable in a number of areas. Given the age and condition of the west standpipe, an interior inspection and a structural assessment are needed to determine when replacement of the east standpipe will be required. The standpipes are not equipped with mixing systems. Although maintaining chlorine residuals has not been an issue, both get significant ice build-up. A water mixing system is needed in each standpipe.

Innisfil Master Servicing Plan Update Final Draft Report
Page 105 July 13, 2018
It is estimated that the majority of the watermains in the Cookstown distribution system were installed in the 1970s. Many of these watermains are made of asbestos cement and there are a number of 100 mm diameter pipes, which are smaller than the minimum diameter recommended by the MOECC. A phased watermain replacement plan is needed to upsize small diameter watermain and replace old watermains.
Pressures in the distribution system under maximum day demands vary widely: pressures in the lower elevation areas to the west of Highway 27 can exceed 95 psi, while homes in the higher elevation lands, such as in the Pattson subdivision, need to be equipped with individual booster pumps to obtain the required minimum pressures.
15.1.2W
ater Servicing Solutions
Alternative solutions were considered to improve system pressures in Cookstown:
Alt. 1: New BPS at standpipes to increase pressures in high elevation areas, and install pressure reducing valves (PRV) in low elevation areas.
Alt. 2: Individual booster pumps in high elevation areas (status quo).
Review of the existing water distribution system shows that the area of Cookstown that would benefit from a booster pumping station (Alternative 1) is relatively small compared with the existing areas of Cookstown (more than half) that would need PRVs to maintain pressures below 90 psi if a new BPS increased the pressure in the distribution system. An excessive number of PRVs would therefore need to be installed. On this basis, the status quo is the recommended approach.
15.1.3Recom
mended W
ater Servicing
The following recommended projects are recommended to improve water servicing in Cookstown:
Replacement of the west standpipe if need confirmed from an inspection and structural assessment of the standpipe. Installation of mixing systems in the east and west standpipes. Replacement of all 100 mm diameter watermains with minimum 150 mm diameter pipes. Replacement of aging watermains, as needed.

Page 106 July 13, 2018
15.2.2W
ater Servicing Solutions
The following alternatives were considered to increase the water supply in the Highway 400 and 89 area:
Alt. 1: Extend municipal water servicing from the Highway 89 watermain.
Alt. 2: Continue with private groundwater supply wells.
Alternative 1 would involve increasing the water supply from the Alcona to Bradford water transmission main. The water transmission main and the Third Line BPS were not designed to supply water to the Highway 400 and 89 employment lands. In the absence of spare capacity, the Third Line BPS would need to be expanded and higher velocities allowed in the watermain on Highway 89 to convey the additional flow. In addition, a water storage tank would be required as there is no spare capacity in the Cookstown standpipes.
The availability of an adequate groundwater supply to accommodate the potential increase in the employment land area has not been investigated.
Further review of the feasibility of increasing the water supply from the water transmission main as part of the planned expansion of the system by the Town of BW
G is required.
15.2.3Recom

As shown on Figure 23 overleaf, the Cookstown sanitary sewer system flows to the Cookstown SPS, which pumps raw sewage to the Cookstown W
PCP.
The Cookstown SPS has two pumps with a firm capacity of 30.5 L/s.
The Cookstown WPCP is an extended aeration plant with an ADF capacity of 825 m
3/day. The effluent is discharged to two on-site ponds, from where it is pumped seasonally to Innisfil Creek (October 1 to May 31). For the month of April, the maximum daily mean effluent discharge rate is 60 L/s. From October to March and during May, a maximum daily flow of 10 L/s can be discharged.
In 2017, the Cookstown WPCP was operating at 69%
of its average day rated capacity. The WPCP has
been operating well and has been meeting the required effluent quality and maximum phosphorus loading. Effluent ammonia concentrations have been inconsistent, however in compliance with the limit.
16.1.2W
astewater Servicing Needs
Proposed developments in Cookstown are projected to result in wastewater flows that exceed the capacity of the Cookstown W
PCP. Additional wastewater treatment and effluent disposal capacity, or an alternative servicing approach, is needed. A Municipal Class EA study is underway to identify the preferred solution to provide the required increase in treatment and disposal capacity.
Review of flows recorded at the Cookstown WPCP has shown that the sanitary sewer system conveys
significant amounts of inflow and infiltration (see Section 6.2). A flow monitoring program and identification of sources of inflow and infiltration are needed to devise a control plan and remediation work to reduce the amount of I/I in the collection system.
Existing sewers in Cookstown are adequate to convey the projected future flows except for two 200 mm sewer sections upstream of the W
PCP within the abandoned rail line corridor that are well beyond their maximum capacity.

16.1.3W
astewater Servicing Solutions
As a Municipal Class EA study is underway, this MSP Update study did not review alternative servicing approaches for Cookstown. However, as one of the alternative solutions considered in the Cookstown Class EA is the connection to the Lakeshore wastewater system via the 5 Sideroad, the servicing solutions for the expansion of the Innisfil Heights economic district took into consideration the potential need to convey flows from Cookstown.
16.1.4Recom
mended W
astewater Servicing
Excluding the need to increase the wastewater treatment and disposal capacity, which is being addressed separately by the Cookstown Class EA study, the following measures are recommended for Cookstown:
Inflow and infiltration monitoring study and control plan. Sewer replacement or rehabilitation as required to address issues identified by the I/I study. Replacement of two undersized sewers.
16.2Highw
ay 400 & 89 Area
16.2.1W
astewater System
Needs
The Highway 400 and 89 area is not serviced by municipal sewers. The Cookstown Outlet Mall is serviced by two facultative lagoons and an effluent spray irrigation system. Other commercial properties, the campground, and the few residents in the area are serviced by private septic systems. There are no documented issues with these existing private systems.
The potential expansion of the employment lands area will require a wastewater servicing solution.
16.2.2W
astewater Alternative Solutions
The Municipal Class EA for the Cookstown WPCP is considering alternative solutions for providing
wastewater servicing to the Highway 400/89 area in addition to Cookstown. As this Municipal Class EA study is underway, this MSP Update study did not review alternative servicing approaches for the Highway 400 & 89 area
16.2.3Recom
mended W
astewater Servicing
There is no recommended wastewater servicing infrastructure project for the Highway 400 & 89 area until the Class EA study is completed.

18Recom
mended Im
plementation Plan
The MSP Update identifies the water and wastewater servicing needs - based on existing conditions, projected population and employment growth and development plans - and the projects that are recommended to be implemented to meet those needs. It also identifies a longer-term water and wastewater servicing strategy to meet the expected needs beyond the 2031 horizon. This chapter presents the recommended implementation plan for these projects and summarizes the estimated capital expenditures.
18.1Project Tim
ing and Triggers
The timing of project implementation was estimated in discussions with InnServices and based on growth projections, for the horizons of ‘by 2031’, and ‘post 2031’. The projects in the latter horizon are longer term plans that do not need to, or could not realistically be, implemented in the next 15 years.
The projects that were identified as needed by 2031 were further divided into the projects that should be implemented in the short-term, i.e., in the next 5 years (period 2019 to 2023), and the projects that are anticipated to be needed in the mid-term, i.e., in the following 8 years (period 2024 to 2031). Some of these mid-term projects are implementable only when the shorter-term projects have been constructed.
Although timeframes are suggested in Tables 26 to 31, the implementation of servicing projects will be a function of various triggers and phasing, rather than estimated dates based on growth projections. These triggers include actual development proposals and phasing plans, actual increases in water demands and wastewater flows, County and municipal road projects, funding opportunities, changes in conditions and needs, and financial considerations. The MSP Update is therefore an overall map that shows how the municipal water and wastewater infrastructure should and will evolve, and sets the priorities for the proposed works. Flexibility in the implementation of the servicing plan will, however, be necessary.
18.2Estim
ated Project Costs
The estimated project costs for all recommended projects are summarized in Tables 26 to 31. Detailed cost estimates are attached in Appendix B.
All cost estimates were developed on the basis of the projected wastewater flows and water demands (presented in Chapter 5) for existing serviced areas and planned developments within the settlement areas. Costs were developed based on conceptual design work and preliminary sizing of watermains, sewers, pumping stations and forcemains. They are based on 2017 pricing. The cost estimates should be considered as opinions of probable costs for budgeting purposes, subject to refinement following detailed design, and should be updated or adjusted for inflation.
Innisfil Master Servicing Plan Update Final Draft Report
Page 118 July 13, 2018
The cost estimates for the expansions of the Lakeshore WTP and Lakeshore W
WTP were taken from
the respective Class EA studies, and adjusted for inflation at 2% per annum.
All cost estimates include allowances for contingencies (25%), engineering (10%
for linear works and 15%
for complex works), and InnServices internal costs of $25,000 to $100,000 per project.
18.3Recom
mended W
ater Master Servicing Plan
The recommended water servicing projects and the potential future water servicing projects, some of which as local improvement projects, are shown on Figure 24.
The municipal projects, suggested to be implemented in the short-term, mid-term and long term are summarized in Tables 26, 27 and 28. These tables present the estimated project costs, the expected triggers for their implementation, and the Class EA requirements.
18.3.1Short-Term
Water Projects
Innisfil Beach Road Phase 1 Waterm
ain and Alcona Reservoir Booster Pumping Station
Project
The extension of trunk watermains on Innisfil Beach Road to Yonge Street will be implemented in conjunction with the County’s planned road reconstruction project stating in 2019. This project is the first building block of the Innisfil Heights water servicing plan.
The construction of a new booster pumping station at the Alcona Reservoir site will be needed to service the Town Campus beyond the current plans (IHP Health Hub) and supply water to Stroud, Innisfil Heights and developments in Alcona South. A separate Class EA study is not required for this project.
Alcona Zone 2 Booster Pumping Station Upgrade Project
Upgrades to the Zone 2 booster pumping station in Alcona will be needed to service the proposed developments in Alcona North that are in Pressure Zone 2.
Stroud Water Servicing Project
The extension of a watermain on Yonge Street to the Stroud reservoir is a project that could be implemented as soon as the Innisfil Beach Road Phase 1 watermain and Alcona Reservoir BPS are commissioned. If the Stroud groundwater supply can be upgraded reliably with a new well, this project can be postponed.

Waterm
ain Looping in Alcona
Installation of additional watermains in Alcona where dead ends exist is recommended to improve fire flow availability in support of intensification plans. Specific watermain looping projects will be triggered by development plans.
Alcona Reservoir Expansion Project
The addition of the third cell of the Alcona Reservoir will be triggered by increases in the population serviced by the Lakeshore water system, mainly in Alcona and Sandy Cove. The reservoir expansion is recommended to be implemented once the water distribution system to the Alcona South and North growth areas is built.
Innisfil Heights Reservoir and BPS Phase 2 Expansion Project
The Phase 2 expansion of the Innisfil Heights reservoir and BPS will be required when approximately 50%
of the lands within the existing Innisfil Heights economic district are developed (when MDD reach 45 L/s).
Trunk Waterm
ain from Lakeshore W
TP to Alcona Reservoir Project
The additional feed watermain to the Alcona Reservoir from the Lakeshore WTP will need to be built to
supplement the existing Innisfil Beach Road trunk watermain once the combined water demands from Innisfil and BW
G reach approximately 60 ML/day. This is expected to occur by 2031 if the Innisfil Heights economic district develops as planned and if BW
G’s water demand projections are achieved. The 9th
Line section of the trunk watermain may be installed earlier in conjunction with the 9th Line sanitary sewer
project, which will be required to service the Alcona North growth area.
Alcona Zone 3 Booster Pumping Station Project
The pressure zone 3 booster pumping station in Alcona North will be required to service part of the development in Alcona North, and could be implemented once the new trunk watermain from the W
TP to the Alcona Reservoir is constructed. A Class EA Schedule B study will need to be completed to establish the preferred site for the booster pumping station.
Lefroy Booster Pumping Station Expansion Project
Replacement of the pumps at the Lefroy booster pumping station will be required when the water demands reach the capacity of the stage 1 pumps (MDD of 15 L/s), which were designed for servicing approximately 800 equivalent residential units.

Killarney Beach Road Waterm
ain Project
The installation of a trunk watermain on Killarney Beach Road, including a PRV to allow the connection between the Lefroy Pressure Zone 2 and the Alcona Pressure Zone 1, is required to service proposed developments east of the railway line, as well as south of Killarney Beach Road. The project should be coordinated with the Killarney Beach Road sanitary sewer twinning project.
Cookstown W
atermain Replacem
ent Project
The extent of the replacement of small diameter and old watermains in Cookstown will be determined following a watermain condition assessment study.
Lakeshore Water Treatm
ent Plant Phase 3B Expansion Project
The next phase of expansion of the Lakeshore WTP (Phase 3B) is expected to be required before 2031
if the water demands in Innisfil continue to increase as planned. The project will include the twinning of the raw water intake. Design of the expansion should be initiated when the total MDD reach approximately 30 ML/day.
18.3.3Long-Term
(Post 2031) Water Projects
Expansion of the Innisfil Heights economic district south of the 7 th Line is expected to be the trigger for the following projects:
Yonge Street and 6 th Line Twin Waterm
ains. With these projects, the water distribution system
will be extended from Innisfil Beach Road to the 6th Line, and will bring a water supply to the potential
Campus Node and to the future 6 th Line Reservoir and BPS. The projects may be implemented in one or two phases. A first phase may consist of extending the watermains only to the Campus Node if the Campus Node requires servicing prior to Innisfil Heights. Alternatively, the construction of watermains on 6 th Line may occur concurrently with the reconstruction of 6 th Line and/or the installation of sanitary sewers on 6 th Line.
6 th Line Reservoir and BPS and 6 th Line Waterm
ain to Innisfil Heights, which will supply water to the water distribution system for the expansion of the Innisfil Heights economic district.
Innisfil Heights Waterm
ains Phase 2 Project. The installation of trunk watermains in Innisfil Heights south of 7 th Line and a new watermain crossing of Highway 400 at the 6 th Line, will be required to service the expansion of the economic district. The highway watermain crossing should be coordinated with the sanitary forcemain crossing.
Expansion of the Alcona Reservoir Booster Pumping Station. Replacement of pumps at the
Alcona Reservoir booster pumping station, and associated electrical upgrades, will be required to supply the increase in water demands in Innisfil Heights.
Innisfil Master Servicing Plan Update Final Draft Report
Page 126 July 13, 2018
Lefroy Reservoir Phase 2 Expansion Project
The addition of two cells at the Lefroy Reservoir will only be required if the water service area is extended within Lefroy and to Innisfil South.
Lakeshore Water Treatm
ent Plant Phase 3C Expansion Project
The Phase 3C expansion of the Lakeshore WTP will need to be in place when the total water demands
from Innisfil and BWG reach 55 ML/day (MDD). Design of the expansion should be initiated when the
total MDD reaches approximately 75% of the W
TP’s rated capacity.

18.7Further Studies
18.7.1Class Environm
ental Assessment Studies
In accordance with the Municipal Engineers Association, plans for municipal water and wastewater pumping stations, new or upgrades, should be developed under the Class Environmental Assessment process for Schedule B undertakings. The Class EA requirements for some of the projects identified in this MSP Update are considered completed under this Master Plan Class EA, however, there are a number of projects that will require further assessment of alternatives and potential impacts on existing environmental and social conditions, to ensure that the preferred conceptual design is selected and adequate mitigating measures are identified. The projects that require further Class EA studies were identified in Tables 26 to 31.
18.7.2Other Recom
mended Studies
Prior to the implementation of some of the capital projects identified in this MSP Update, the following studies should be completed to either refine the scope of the capital project, confirm the timeline of the project, confirm the feasibility, and/or determine if additional capital projects are needed to address concerns with existing conditions.
Stroud hydrogeological investigation. This study is required to identify a short-term solution to the absence of firm groundwater supply capacity, which is needed for a reliable water supply and to enable new developments to be serviced.
Cookstown watermain condition assessm
ent. This study is needed to determine which watermains should be replaced.
Cookstown west standpipe condition and structural assessment. This assessment will provide
the information required to determine the required timeline to the replacement of the west standpipe.
Lakeshore WPCP optim
ization study. The goal of the optimization study is to identify short-term measures to increase the W
PCP’s capacity and improve performance.
Lakeshore WPCP expansion design. The preliminary design should consider both Stages 3 and
4 expansions to ensure cost efficiencies are built in the expansion plans. Preliminary and final design of the Stage 3 expansion needs to be completed immediately.
Inflow and Infiltration monitoring and control studies for Alcona and Cookstown. The studies
will identify opportunities for reducing wet weather induced extraneous flows and recommend repair, rehabilitation and/or replacement of sewer infrastructure, or disconnection of sump pumps, that should be implemented to reduce per capita wastewater flows and increase the W
PCP’s future serviced population.

Highway 400 & 89 water servicing feasibility study. This study should be conducted as a result of development proposals, to determine the implications of increasing the water taking from the Alcona to Bradford water transmission main to service growth of employment lands in the Highway 400 and 89 area.
Purple Pipe feasibility study. This study should be conducted to assess the potential interest, costs and benefits of implementing a wastewater reuse pipe for irrigation and industrial uses.

mendations
18.8.1Tow
n Engineering Standards Update
Differences between the design criteria used in the 2012 MSP Update and the ones recommended in the Town of Innisfil Engineering Design Standards (2016) have caused difficulty to both engineers and reviewers when determining the appropriate design basis for servicing plans for development proposals. Alignment of the Town Standards with the adopted MSP would eliminate this difficulty.
It is recommended that the Town Standards for the design of water and wastewater linear and vertical infrastructure be updated to reflect the criteria outlined in Chapter 6. These updated criteria are summarized in Tables 35 and 36.

18.8.2Allocated Capacity Updates
It is recommended that InnServices, in cooperation with the Town’s Planning department, develop and maintain up-to-date (annual) capacity allocation tables for each water system and wastewater system to determine more accurately when the next facility expansions will be required.
The intent is to use these allocation tables to assist in planning for the expansions of the major infrastructure in a timely manner, and to provide a clear benchmark for the review of proposed development servicing requests. These allocation tables must be kept up-to-date in order to be a useful tool.
Tables of actual and allocated flows for each of the following systems should be prepared:
Lakeshore water system (overall summary to include all areas that are supplied by the Lakeshore W
TP, including Lefroy, Cookstown and BWG, and Innisfil Heights and Stroud when connected)
Lefroy BPS and reservoir Innisfil Heights BPS and reservoir Churchill water system Stroud water systemLakeshore W
WTP

Cookstown WW
TP
These tables should tally the following, as a minimum, for each of the water and wastewater systems:
Actual flows and number of serviced customers. Potential servicing of unserviced lots: existing lots that could potentially connect to the system because they front on existing watermains or sewers. Potential intensification: existing serviced lots that could be redeveloped at a higher density.Allocations Residential: list of residential developments/lots with allocation (registered). Allocations ICI: list of industrial, commercial and institutional developments/lots with allocation (registered).Future Residential and Future ICI: these development proposals would be organized based on their planning approval status (draft plan approved, submitted, expected, etc).
The tables should clearly state the basis for the estimated future water demands and wastewater flows including the number and type of lots and population or area, the flow criteria, which should be based on updated Town Standards, and the source of the information for each development.
