Executive Summary
This document provides a cost estimate for the preferred Alternative to the Undertaking, as described in the Technical Concept Level 2 Document. It will be used for reference purposes for assessing the short list of Alternative Methods of Carrying Out the Undertaking, in accordance with the Minister-approved (as amended) Upper York Sewage Solutions Environmental Assessment (UYSS EA) Terms of Reference in March 2010. York Region confirmed the Innovative Wastewater Treatment Technologies (Lake Simcoe Water Reclamation Centre) alternative as the Preferred Alternative for developing a sustainable sewage servicing solution to accommodate the growth forecasted to occur in the UYSS service area. This forecast is in accordance with both the provincial growth management policies outlined in the Growth Plan pursuant to the Places to Grow Act, 2005 and applicable environmental legislation including, but not limited to, the Lake Simcoe Protection Act, 2008, the Oak Ridges Moraine Conservation Act, 2001, the Greenbelt Act, 2005, and the Ontario Water Resources Act. The UYSS service area consists of the growth portions of the Towns of Aurora, Newmarket, and portions of East Gwillimbury, including Queensville, Holland Landing, and Sharon. The wastewater servicing capacity required to accommodate only the growth forecasted to occur in the UYSS service area to the year 2031 is 47.2 megalitres per day (MLD) annual average day flow. However, including residences currently serviced by existing private on-site septic systems and residences currently serviced by the Holland Landing Water Pollution Control Plant (Lagoons) in East Gwillimbury, capacity for the UYSS service area of 53 MLD (52.8 MLD) is required. The Preferred Alternative (Innovative Wastewater Treatment Technologies) consists of: A new 40 MLD Annual Average Day Flow Water Reclamation Centre which would
produce treated clean water suitable both for discharge to the East Holland River and reclaimed water applications
Use of an approved watershed Total Phosphorus off-setting program (either using project specific phosphorus off-sets to maintain the total phosphorus load within the current allocation for the Queensville / Holland Landing Lagoon which would be decommissioned
Modifications to the existing York Durham Sewage System (YDSS) to provide additional system reliability during high flow conditions to accommodate sewage flow from approved growth from the Towns of Aurora and Newmarket
Lake Simcoe Water Reclamation Centre An advanced treatment process has been selected for the new Lake Simcoe Water Reclamation Centre to produce both treated clean water suitable for discharge to the Lake Simcoe watershed and reclaimed water for various end uses. Additionally, the treatment process selected would be capable of reaching the very low Total Phosphorus limits required

under the Lake Simcoe Phosphorus Reduction Strategy (2010). In general, the liquid process would consist of a headworks (screenings and grit removal), primary treatment, flow balancing tanks, conventional activated sludge with biological nutrient removal, chemical addition, secondary clarifiers, and tertiary and quaternary phases consisting of low pressure membranes (microfiltration), high pressure membranes (reverse osmosis), reverse osmosis concentrate treatment, disinfection, and a final outfall. Biosolids management would include primary gravity thickeners/fermenters, waste activated sludge thickening, anaerobic digestion, biosolids storage, and an option for digested sludge dewatering. All unit operations which have the potential to generate odour would be contained and the air treated prior to discharge to the atmosphere. The design of buffer zones around the plant would further reduce the potential for odour incidents occurring off site. This document reports the capital cost, operation and maintenance and Net Present Value estimates for a short list of five (5) sites on which the Water Reclamation Centre could be constructed and the associated conveyance infrastructure to and from the sites. The short list of sites is as follows: Site 24 – located on the west side of 2nd Concession approximately 500 metres (m)
north of the intersection at 2nd Concession and Queensville Sideroad
Site 30 – located on the east side of Leslie Street approximately 500 m south of the intersection at Leslie Street and Holborn Road
Site WH1 West – located on the east side of 2nd Concession approximately 1,000 m north of the intersection at 2nd Concession and Queensville Sideroad
Site WH1 East – located on the west side of Leslie Street approximately 900 m south of the intersection at Leslie Street and Holborn Road
Site WH2 – located on the north east corner of the intersection at 2nd Concession and Queensville Sideroad
A summary of the total Capital and 50-Year Net Present Value Operation and Maintenance Cost Estimate for each site is provided in Table ES1.

proposed modifications would provide sufficient capacity for approved growth to 2031 and relief to the existing conveyance system during periods of extreme high flow or during system maintenance operations at the Newmarket, Bogart Creek, and Aurora Pumping Stations. This document presents the capital cost, operation and maintenance and Net Present Value estimates for the three YDSS Modifications Alternative Routes: Alternative Route A – A new Newmarket forcemain that parallels the existing
Newmarket forcemain route and is 5.4 kilometres (km) in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Cotter Street.
Alternative Route B – A new Newmarket forcemain that parallels the existing Newmarket forcemain route for two thirds of its length and travels south on Prospect Street and west on Mulock Drive for one third of its length. For this alternative, the new Newmarket forcemain is 5.8 km in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Prospect Street.
Alternative Route C – A new Newmarket forcemain that parallels the existing Newmarket forcemain route for one fourth of its length, travels south on Prospect Street and Bayview Avenue and west on St.John’s Sideroad for three fourths of its length. For this alternative, the new Newmarket forcemain is 7.1 km in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Prospect Street.

The Preferred Alternative to the Undertaking (comprised of the Lake Simcoe Water Reclamation Centre and the YDSS modifications) as well as an overview of the Alternative Methods for the Preferred Alternative are provided in Section 2.0. The Methodology used to develop the capital and operating cost estimates, as well as the 50 year Net Present Value is described in Section 3.0. Section 4.0 provides the cost estimates for the Alternative Methods associated with the Water Reclamation Centre, while Section 5.0 provides the cost estimates for the Alternative Methods associated with the YDSS modifications. The capital, operating and 50-Year Net Present Value cost estimates are summarized in Section 6.0 for all of the Alternative Methods.
Section 2.0 Description of the Preferred Alternative To the Undertaking
The Lake Simcoe Water Reclamation Centre Preferred Alternative is comprised of two components: the Water Reclamation Centre and the YDSS Modifications. As part of the Minister-approved (as amended) UYSS EA Terms of Reference, the purpose of the proposed undertaking was defined as developing a sustainable sewage servicing solution that could accommodate the growth that is forecasted to occur in the UYSS service area in accordance with both the provincial growth management policies outlined in the Growth Plan pursuant to the Places to Grow Act, 2005 and applicable environmental legislation including, but not limited to, the Lake Simcoe Protection Act, 2008, the Oak Ridges Moraine Conservation Act, 2001, the Greenbelt Act, 2005, and the Ontario Water Resources Act. The UYSS service area consists of the Towns of Aurora, Newmarket, and portions of East Gwillimbury, including Queensville, Holland Landing, and Sharon (QHLS). York Region confirmed the Lake Simcoe Water Reclamation Centre alternative with YDSS Modifications as the Preferred Alternative To the Undertaking. As part of this alternative, wastewater resulting from growth in the Town of Aurora and a portion of the Town of Newmarket would be conveyed through the YDSS for treatment at the Duffin Creek Water Pollution Control Plant (WPCP) and discharged to Lake Ontario. To accommodate this, modifications to the existing YDSS in the Town of Newmarket would be required. Wastewater from growth in the Town of East Gwillimbury and a portion of the Town of Newmarket would be conveyed to the proposed Water Reclamation Centre for treatment, using a wastewater purification system and water recycling facilities so that the treated clean water would be discharged to the East Holland River within the Lake Simcoe watershed.

Since the Preferred Alternative includes a Water Reclamation Centre, potential locations for this facility needed to be identified for further assessment and comparative evaluation leading to the identification of a recommended site. The process for generating and screening potential alternative Water Reclamation Centre sites was carried out in accordance with the Alternative Methods of Carrying Out the Undertaking methodology provided in the UYSS EA Minister-approved (as amended) Terms of Reference and lead to the development of a short list of five alternative sites. The Preferred Alternative to the Undertaking also included modifications to the existing YDSS which resulted in the identification of three alternative routes for the additional conveyance capacity. An overview of the Alternative Methods is provided in the following sections.
2.1 Lake Simcoe Water Reclamation Centre
Wastewater from growth in the Town of East Gwillimbury and a portion of the Town of Newmarket would be conveyed to the new Lake Simcoe Water Reclamation Centre for treatment, using innovative wastewater treatment technologies. The treated clean water would be discharged in accordance with Ontario Ministry of the Environment (MOE) requirements to the Lake Simcoe watershed. A portion of the clean water may also be used for various reuse opportunities within the watershed. The Water Reclamation Centre would be designed for an average capacity of 40 megalitres per day (MLD). The Lake Simcoe Water Reclamation Centre requires the following works: Water Reclamation Centre process plant (i.e. works associated with construction and
operation of the treatment works)
Water Reclamation Centre site preparation (i.e. earthworks and foundations necessary to facilitate construction of the process plant. Site property costs are also included.)
Wastewater conveyance to the Water Reclamation Centre, discharge of treated clean water to the East Holland River via an outfall along Queensville Sideroad, and transfer of Reverse Osmosis (RO) Concentrate from the Water Reclamation Centre to the Newmarket Pumping Station
Reclaimed water transfer from the Water Reclamation Centre to end users
Total phosphorus (TP) off-setting
As described in theScreening of the Long List of Potential Alternative Water Reclamation Centre Sites and Development of the York Durham Sewage System Modifications report, four Sites (Sites 24, 30, WH1 and WH2) were selected as the short list of alternative Water Reclamation Centre Sites to be carried forward for assessment and comparative evaluation.

As part of the development of a conceptual design layout for each of the short list of alternative Water Reclamation Centre Sites, Site WH1, due to its size, suitable area, and potential accesses from 2nd Concession and Leslie Street presented an opportunity to further sub-divide the Site into two separate conceptual design layouts: Site WH1 West (with access onto 2nd Concession) and Site WH1 East (with access onto Leslie Street). As such, this document reports the capital cost, operation and maintenance and Net Present Value estimates for a short list of five (5) sites on which the Water Reclamation Centre could be constructed and the associated conveyance infrastructure to and from the sites. Figure 2.1 shows the locations of the five sites. The existing Holland Landing WPCP (Lagoons) site is also shown for reference.
The short list of sites is as follows:
Site 24 – located on the west side of 2nd Concession approximately 500 metres (m)north of the intersection at 2nd Concession and Queensville Sideroad
Site 30 – located on the east side of Leslie Street approximately 500 m south of theintersection at Leslie Street and Holborn Road
Site WH1 West – located on the east side of 2nd Concession approximately 1,000 mnorth of the intersection at 2nd Concession and Queensville Sideroad
Site WH1 East – located on the west side of Leslie Street approximately 900 m south ofthe intersection at Leslie Street and Holborn Road

2.2 York Durham Sewage System Modifications
Modifications of the existing York Durham Sewage System (YDSS) are required to provide additional system reliability during high flow conditions and to accommodate additional flows from the approved growth in the Towns of Newmarket and Aurora. The modifications would provide sufficient capacity for approved growth to 2031 and relief to the existing conveyance system during periods of extreme high flow, such as wet weather events (snowmelt, rainstorms) or during system maintenance operations at the Newmarket, Bogart Creek, and Aurora Pumping Stations. The modifications to the existing YDSS will include the following: A second forcemain (new Newmarket forcemain) from the existing Newmarket Pumping
Station directly to the Aurora Pumping Station or to the existing gravity sewer, which discharges to the Aurora Pumping Station
A second forcemain (new Bogart Creek forcemain) from the existing Bogart Creek Pumping Station to the new Newmarket forcemain
Modifications to the Newmarket and Bogart Creek Pumping Stations for connection of the two new forcemains
This document presents the capital cost, operation and maintenance and Net Present Value estimates for the three YDSS Modifications Alternative Routes: Alternative Route A – A new Newmarket forcemain that parallels the existing
Newmarket forcemain route and is 5.4 kilometres (km) in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Cotter Street.
Alternative Route B – A new Newmarket forcemain that parallels the existing Newmarket forcemain route for two thirds of its length and travels south on Prospect Street and west on Mulock Drive for one third of its length. For this alternative, the new Newmarket forcemain is 5.8 km in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Prospect Street.
Alternative Route C – A new Newmarket forcemain that parallels the existing Newmarket forcemain route for one fourth of its length, travels south on Prospect Street and Bayview Avenue and west on St.John’s Sideroad for three fourths of its length. For this alternative, the new Newmarket forcemain is 7.1 km in length. A new Bogart Creek forcemain from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain on Prospect Street.

Upper York Sewage Solutions EA
Section 3.0 Methodology
The methodology presented in Appendix I (Financial Work Plan) of the Minister-approved (as amended) UYSS EA Terms of Reference was utilized as the basis for generating cost estimates. In general, existing financial sources of information were reviewed to develop a Class 4 Estimate in accordance with the Recommended Practice No. 17R-97 and No. 18R-97 developed by AACE International. These levels of estimates are based on a concept limited scope definition and are used for strategic-level decision-making purposes. The tools used are generally stochastic parametric estimators such as cost-per-unit area or cost-per-unit capacity. The estimates are based on defined location, capacity and technology selection to provide a -20 percent to +40 percent accuracy range. The methodology used financial information from cost estimation manuals2, other projects similar in scope/nature and size, professional judgment and experience based on conceptual level defined parameters, and applied allowances for local market conditions and variability. General contingency costs of 25 percent have been included to allow for uncertainty in the project cost due to such unforeseen factors as, but not limited to: materials and labour pricing changes, unknown site conditions, how work will be performed, design developments and scope changes. An allowance of 25 percent for engineering, legal, administrative and field services costs to design and construct the works has been added to the total capital plus general contingency cost. All costs are rounded to the nearest $10,000.
3.1 Capital Costs
The capital cost estimates generated for the short list of alternative Water Reclamation Centre Sites and YDSS Modifications Alternative Routes include overheads and contingencies and are based on a number of assumptions. All costs are in year 2012 Canadian dollars. In particular, overheads are included for labour, material, sub-contractors, equipment and general conditions, but exclude tax, engineering, legal, administration and field services fees. The 25 percent general contingency cost and 25 percent engineering, legal, administrative and field services costs have been included. The following assumptions form the basis for developing the capital costs: The Water Reclamation Centre would be built for the full 40 MLD capacity. Potential
phasing of construction will be considered at the preliminary design phase. Phasing is not anticipated to alter the selection of the preferred alternative.

For the planning horizon, the design flows are:
- annual average day flow is 40 MLD
- peak month average day flow is 52 MLD (peaking factor of 1.3)
- peak daily flow is 80 MLD (peaking factor of 2.0)
- peak hourly flow is 114 MLD (peaking factor of 2.9)
The treatment and disposal processes would incorporate environmentally sustainable practices and be designed to create a minimal carbon footprint.
All demolished and removed materials will be disposed of at a site no further than 16 kilometres from the work site. No disposal fees have been included.
Conveyance infrastructure will be located within existing road right-of-ways, existing easements or modifiable easements.
Pipe sizes are approximate and subject to change during detailed design.
A conveyance infrastructure dewatering allowance has been assumed due to unknown groundwater conditions.
Sites 24 and WH1 West are relatively flat and the costs to scrape 0.33 m of vegetation have been included in the cut-to-fill volumes.
Earthworks cut-to-fill costs are based on soils consisting of common earth and with no clay present, excavated materials are suitable for use as backfill, fill includes wetting soil with water and compacting in lifts, and earthwork will be carried out using 11.5 cubic metre (15 cubic yard) towed scraper, ¼ push dozer, and sheep’s foot compactor. No costs have been included for rock excavation or removal, dewatering, avoidance or removal of unidentified obstructions, lime or other soil stabilization.
A 30 percent allowance has been included in the cut-and-fill soil volumes to account for variances in future contours of the sites.
The Geotechnical report indicated that the sites on Leslie Street (Sites 30 and WH1 East) had suitable bearing capacity for the Water Reclamation Centre structures and no allowances were carried for deep foundations (piles) for these sites.
The Geotechnical report indicated that the sites on 2nd Concession (Sites 24, WH1 West, and WH2) had suitable bearing capacity for foundation loads up to 200 kpa. Most of the Water Reclamation Centre structures will have design foundation loadings of less than 200 kpa. However, there is potential the foundation loads for a few structures such as the liquid biosolids storage tanks could be above 200 kpa depending on the final height of these tanks. For Sites 24, WH1 West, and WH2, the deep foundation allowance carried in the Alternative To the Undertaking Cost Estimate of $21.9 million (including contingency and engineering, legal, administrative and field services allowance), was included in this estimate.
Property costs for acquisition of sites has been based on a land unit rate of $50,000/acre. A 15 percent allowance for legal costs and taxes has been added to property costs. The 25 percent contingency and 25 percent engineering/ legal/ administration/ field services allowance was not applied to land acquisition.
No costs have been included for inspection, testing, remediation or removal of contaminated or hazardous materials.

All work will be performed under the same contract and during a continuous construction schedule (i.e., it has been assumed only one general contractor and one mobilization).
All labour and material pricing is based on current rates with no accounting for future labour or material escalation.
3.2 Operation and Maintenance Costs
Similar to the capital cost estimates generated for the short list of alternative Water Reclamation Centre Sites and YDSS Modifications Alternative Routes, operation and maintenance costs were also developed based on a number of assumptions. These assumptions include the following: Water Reclamation Centre process plant operation and maintenance costs were based
on replacement of mechanical equipment in Year 20 and Year 40. The mechanical equipment costs were calculated as 30 percent of the capital cost estimate.
Operating costs for the Water Reclamation Centre conveyance are based on the power requirements to transfer water (power for conveyance to the Water Reclamation Centre based on 40 MLD, power for transfer of RO Concentrate to Newmarket Pumping Station based on 6 MLD).
Operating costs for the YDSS modifications are based on the power requirements to transfer wastewater (power for conveyance from the Newmarket Pumping Station to Aurora Pumping Station based on an annual average day flow at the Newmarket Pumping Station of 39.8 MLD for year 2031).
Operation and maintenance costs for the Water Reclamation Centre conveyance infrastructure, reclaimed water conveyance and YDSS modifications include an allowance for maintenance of 0.25 percent of capital costs estimate. Maintenance activities would include exercising and repairing valves, pipe inspection, line flushing, etc.
A standard 40-hour work week has been assumed.
Labour costs are based on current wage rates published by RS Means3 for the Toronto area.
It has been assumed that a labour pool of adequate quantity and quality exists in the immediate project area.
Electrical rate of $0.10 per kWh.
3.3 Net Present Value
Net Present Value calculations were based on 50 years and a 5 percent discount rate and have been applied to the operation and maintenance costs.

Section 4.0 Water Reclamation Centre
The cost for the Water Reclamation Centre component of the Preferred Alternative is comprised of five components: The process plant
Preparation of the site
Conveyance to and from the site
Transfer of reclaimed water to the end users
Total phosphorus offsets.
The cost estimate for each component is provided in the following sections.
4.1 Water Reclamation Centre Process Plant
The Water Reclamation Centre would discharge treated clean water to the East Holland River (Lake Simcoe watershed). A stringent effluent limit for phosphorus for this discharge would require a highly advanced quaternary level of treatment, involving reverse osmosis (RO) treatment technology, a process capable of removing nutrients from the wastewater to extremely low levels. The Water Reclamation Centre would also be designed to produce a nutrient-rich effluent stream that can be used for irrigation (e.g., sod farms, golf courses, tree farms) during the growing season. To produce two very different end use water quality objectives at the same time, parallel treatment trains with different modes of operation are required. The treatment train for discharge to the East Holland River must produce an effluent that has minimal nutrients and is beneficial to the Lake Simcoe watershed. Following preliminary treatment consisting of screening and grit removal, the discharge treatment train for discharge to the East Holland River would include: Chemically enhanced primary treatment (for enhanced removal of solids and
phosphorus)
Flow balancing tanks
A biological nitrification – denitrification process in bioreactors (which would remove organics and nitrogen)
Filtration (to remove particles prior to reverse osmosis)
Reverse osmosis
Conveyance of the reverse osmosis byproduct stream (Reverse Osmosis Concentrate) to the YDSS for subsequent treatment at the Duffin Creek Water Pollution Control Plant (WPCP)

Post-RO conditioning to ensure adequate dissolved oxygen and alkalinity / hardness to protect aquatic life
Disinfection
The reclaimed water treatment train, in contrast, is a more simple treatment process designed to produce a nutrient-rich effluent, suitable for land application. Following preliminary treatment, the reclaimed water treatment train would include: Conventional primary treatment without chemical addition to leave soluble phosphorus
for fertilization
Flow balancing tanks
Activated sludge secondary treatment using a short solids retention time (or “sludge age”) to remove organics only and not ammonia which is a desirable fertilizer
Filtration (to remove particles)
Disinfection
To allow for the most future flexibility regarding biosolids management, it was assumed that the process would be designed to accommodate anaerobically digested biosolids in the form of both liquid and cake. The cost difference for process equipment will not be significant between the alternate Water Reclamation Centre sites, as a result, the Water Reclamation Centre capital costs are considered to be equal for all of the sites. Process flow diagrams for the Water Reclamation Centre, shown broken into conventional treatment (primary and secondary treatment), advanced treatment (tertiary and quaternary treatment) and solids management are included in Appendix A. Table 4.1 provides the Capital Cost Estimate by unit operation, including a full list of buildings, equipment and sizing. The Operation and Maintenance Cost Estimate is provided in Table 4.2.

4.2 Water Reclamation Centre Site Preparation
Property costs for site acquisition have been based on a land unit rate of $50,000 per acre ($123,600 per hectare) and calculated based on the total property size. An additional 15 percent allowance for legal costs and taxes has been added to the cost of each property. The mass earthworks required on each of the short-listed alternative Water Reclamation Centre sites were calculated based on existing survey data for each alternative Water Reclamation Centre site, and include: Cut to fill quantities required to reach a benchmark level to balance the sites
Placement of a 3 m high earthwork berm on three sides of the site for screening purposes
Construction of a stormwater basin
Cut-to-fill quantities include a 30 percent allowance for variances in the future contours of the site.

4.4 Reclaimed Water Transfer
Potential reclaimed water applications for the UYSS EA include irrigation (e.g. sod farms, golf courses, tree farms) during the growing season. The reclaimed water transfer line capacity requirements were based on preliminary estimates of irrigation area, season (number of months) and estimated flow demands. As customers have not been confirmed for the reclaimed water, the reclaimed water distribution system cost has been assumed equal for all sites.

Alternative Methods of Carrying Out the Undertaking – Cost Estimates
Upper York Sewage Solutions EA
Operating costs for the reclaimed water transfer system are for operation of the reclaimed water pumping station, which is located within the Water Reclamation Centre. Therefore operating costs have been incorporated into the Water Reclamation Centre Process Plant. Only maintenance costs, which apply to the infrastructure outside of the Water Reclamation Centre property are included here. The Capital Cost Estimate is provided in Table 4.23. The annual operation and maintenance Cost Estimate is provided in Table 4.24. Table 4.23: Capital Cost Estimate for Reclaimed Water Transfer

4.5 Total Phosphorus Offsets
The Lake Simcoe Water Reclamation Centre is limited to a net discharge of total phosphorus of 124 kg total phosphorus per year. When the Water Reclamation Centre approaches its 40 MLD rated capacity, it will generate approximately 100 kg/yr of new phosphorus to the East Holland River sub watershed. This load will be addressed through project-specific phosphorus offsets.
050278 (98) Page 51 York Region No. 74270
Alternative Methods of Carrying Out the Undertaking – Cost Estimates
Upper York Sewage Solutions EA
The reduction of phosphorus from other sources would occur from a variety of practices as listed below. Implement enhanced total phosphorus removal systems at existing stormwater retention
ponds located in the watershed.
Removal of aged and potentially failing on-site septic systems located within 100 m of a surface watercourse.
Changes in existing land management practices resulting in a net reduction of total phosphorus.
Cost allowances have been included to cover this total phosphorus off-setting program: The project specific phosphorus off-setting program would address this increase through a minimum of 2:1 reduction of other sources of phosphorus such as stormwater runoff. A reduction of 4:1 removed from the watershed (minimum 400 kg total phosphorus) was used as a conservative basis for the cost estimate. The phosphorus off-setting program allowance was based on the capital cost to enhance 13 existing stormwater management ponds for Total Phosphorus removal based on the guidelines in the MOE’s “Stormwater Management Practices Planning and Design Manual”, (1994). The costs for off-setting total phosphorus discharge to Lake Simcoe will be the same for all sites. No operation and maintenance cost was allowed for the Phosphorus Off-sets as it is anticipated that the end-users of the infrastructure will operate and maintain the facilities. For example, stormwater pond improvements in the Town of East Gwillimbury would be operated and maintained by the Town following construction by York Region. The Capital Cost Estimate is included in Table 4.25. Table 4.25: Capital Cost Estimate of Total Phosphorus Offsets

Section 5.0 York Durham Sewage System Modifications
All YDSS Modifications Alternative Routes (Alternative A, B and C) are in existing modifiable easements or road right-of-ways within the Towns of Newmarket and Aurora. Guiding principles were established to develop the YDSS modifications. These guiding principles are: Maximize the use of road/utility rights-of-way and/or Regional or modifiable existing
easements, so that the need for private land acquisition is minimized or eliminated
Maximize the use of existing infrastructure to avoid the need for significant upgrades to the existing Newmarket and Bogart Creek Pumping Station (minimize capital and operating costs)
Based on the guiding principles, three alternative routes for additional wastewater conveyance from the existing Newmarket and Bogart Creek Pumping Stations to the existing Aurora Pumping Station and existing YDSS were developed. Plan and profile drawings of the alternative route conveyance infrastructure are included in Appendix C.
5.1 Alternative Route A
Alternative Route A includes a new Newmarket forcemain that parallels the existing Newmarket forcemain route and is 5.4 km in length. The new Newmarket forcemain conveys wastewater south from the Newmarket Pumping Station on Bayview Parkway to the existing Newmarket 1050 mm diameter gravity sewer in Bailey Ecological Park, 1.4 km south of Mullock Drive. The existing Newmarket 1,050 mm diameter gravity sewer ultimately discharges to the Aurora Pumping Station on St.John’s Sideroad. As part of this alternative, a new Bogart Creek forcemain will convey wastewater west from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain interconnection on Cotter Street.
050278 (98) Page 53 York Region No. 74270
Alternative Methods of Carrying Out the Undertaking – Cost Estimates
Upper York Sewage Solutions EA
The new Newmarket forcemain will be approximately 900 mm diameter Concrete Pressure Pipe (CPP) for about 2.2 km and 1,050 mm diameter High Density Polyethylene (HDPE) for about 3.2 km. The new Bogart Creek forcemain will be approximately 550 mm diameter HDPE for 0.5 km. Conveyance of wastewater via a new Newmarket forcemain and new Bogart Creek forcemain includes: Installation of approximately 2.2 km of 900 mm diameter CPP forcemains conveying flow
from the Newmarket Pumping Station to parkland south of Concession Street and Wellington Road by open cut
Installation of approximately 0.2 km of 1,050 mm diameter HDPE forcemains for Davis Drive crossing and two railway crossings by Jack and Bore construction methods
Installation of approximately 3.0 km of 1,050 mm diameter HDPE forcemains from the parkland south of Concession Street and Wellington Road to the 1050 mm diameter existing Newmarket gravity sewer by Horizontal Directional Drilling (HDD) construction methods
Installation of 0.5 km of 550 mm diameter HDPE forcemains from the Bogart Creek Pumping Station to the new Newmarket forcemain by HDD construction methods
Valve chambers at a maximum spacing of 500 m
Drain chambers at low points
Removals of the existing urban road and earthworks
General servicing activities including traffic control, utility relocates and dewatering
Road and sidewalk restoration
Siltation control and tree protection
Modifications to the Newmarket and Bogart Creek Pumping Station headers and connection to second forcemain
Table 5.1 provides the Capital Cost Estimate for Route A. The average electrical consumption in 2031 is estimated at 5,150 kW/per day. No additional labour costs are anticipated with the YDSS modifications. The estimated annual operation and maintenance cost is provided in Table 5.2. Table 5.1: Capital Cost Estimate for Route A

5.2 Alternative Route B
Alternative Route B includes a new Newmarket forcemain that parallels the existing Newmarket forcemain route for two thirds of its length and travels south on Prospect Street for one third of its length. For this alternative the new Newmarket forcemain is 5.8 km in length. The new Newmarket forcemain conveys wastewater south from the Newmarket Pumping Station on Bayview Parkway, Prospect Street, west on Mulock Drive and then south to the existing Newmarket 1,050 mm diameter gravity sewer in Bailey Ecological Park, 1.4 km south of Mulock Drive. The existing Newmarket 1,050 mm diameter gravity sewer ultimately discharges to the Aurora Pumping Station on St.John’s Sideroad. As part of this alternative, a new Bogart Creek forcemain will convey wastewater west from Bogart Creek Pumping Station on Pearson Street to the new Newmarket forcemain interconnection on Prospect Street. The new Newmarket forcemain will be approximately 900 mm diameter Concrete Pressure Pipe (CPP) for about 4.3 km and 1050 mm diameter High Density Polyethylene (HDPE) for about 1.5 km. The new Bogart Creek forcemain will be approximately 550 mm diameter HDPE for 0.4 km.
