Introduction The Long Term Water Conservation Strategy identifies a suite of program components that enhance the Regions commitment to innovative water conservation programming, water resource protection, energy conservation and greenhouse gas reduction. These components will be implemented over the period up to 2051.

The Inflow and Infiltration Reduction Strategy outlines efforts required to reduce inflow and infiltration (I/I) in the Region and local municipal systems. By continuing to identify procedures, technologies and methodologies for managing I/I, we can meet or exceed our long-term reduction goal.

1 Background 1.1 Southeast Collector Trunk Sewer Conditions of Approval The Regional Municipality of York (York Region) is in the final phase of constructing the Southeast Collector Trunk Sewer (SEC). The SEC is a 15 kilometer tunneled sanitary trunk sewer that starts in the community of Box Grove in the City of Markham, and ends near the intersection of Finch Avenue and Valley Farm Road in the City of Pickering. This capital project is vital to service provincially-approved growth to the year 2031. On March 31, 2010, the Minister of the Environment of Ontario approved the Individual Environmental Assessment (IEA) for the project and added a number of stringent conditions of approval. Condition 8 of the Ministers Conditions refers to a Water Conservation and Efficiency and Inflow and Infiltration Reduction Monitoring Strategy. The conditions relating to the development of these strategies and their requirements are as follows: Condition 8.1 requires that a Water Conservation and Efficiency Strategy for water and wastewater flows into the SEC be prepared. Condition 8.2 states specifically that York Region is required to develop an Inflow and Infiltration Reduction Strategy, which shall include a program for the reduction of inflow and infiltration by York Region to the Southeast Collector Trunk Sewer from its and its lower tier municipalities sewage systems. This program shall include reduction priorities, targets, timelines, tactics and initiatives, and the associated costs to implement these. Condition 8.4 requires York Region to complete a review of best-in-class water conservation and efficiency programs initiatives, strategies, and tactics adopted by other jurisdictions. A best in class review was also conducted for inflow and infiltration (I/I) reduction programs, initiatives, strategies, and tactics adopted by other jurisdictions.

Figure 1-1: Southeast Collector Trunk Sewer - Shaft 9 at Altona Road Long Term Water Conservation Strategy and Inflow and Infiltration Reduction Strategy Annual Report 2014 1

Development of the new SEC mitigation measures relied on York Regions on-going programs in water conservation and inflow and infiltration (I/I) reduction. Water conservation and I/I reduction have been important parts of York Regions servicing considerations since the first water and wastewater master plan was developed in 1997. The York Durham Sewage System (YDSS) Master Plan, as subsequently updated, specifically identified water conservation and extraneous flow reduction as a significant design consideration for all YDSS projects. In summary, the approval of the SEC is subject to stringent conditions based upon the following overall directions: 1. A compliance monitoring and reporting program is to be established to document

that the project will be undertaken and will continue to be operated in conformance with the commitments made by York Region in the SEC IEA.

2. York Region is required to establish a stakeholder advisory committee, consisting of representatives from local and regional municipalities, agencies, environmental groups, and residents within three months of approval of the SEC IEA to enable on-going liaison between the community and the Region during the construction period. The Southeast Collector Advisory Committee (SeCAC) was formed in April 2010 to meet this requirement.

3. Review of best-in-class water conservation and efficiency measures and development of I/I reduction strategies are to be completed in conjunction with York Region and the local municipalities. It is to be independently peer reviewed, presented to the advisory committee, submitted to the Ministry of the Environment (MOE), implemented, monitored and reported on annually to the MOE.

4. A performance management plan be developed and submitted to the SeCAC and the MOE to document performance targets for improvements to water conservation, efficiency, and reductions in I/I.

Long Term Water Conservation Strategy and Inflow and Infiltration Reduction Strategy Annual Report 2014 2

Seventeen per cent of 2031 Strategy target has been achieved through inflow and infiltration reduction work implemented to date Since implementation of the Inflow and Infiltration Reduction Strategy, remedial works completed across the York-Durham Sewage System have provided 7.02 megalitres of inflow and infiltration flow reduction or 17 per cent of the ultimate target reduction. The Developer-funded Inflow and Infiltration Reduction Pilot Program is only a small component of the overall Strategy and with this multi-faced program approach, the Region is on track to achieve Strategy targets. The Region will continue to work in partnership with both the local municipalities and developers to achieve the inflow and infiltration reduction target of 40 megalitres through the following areas:

Comprehensive flow monitoring program and system analysis Investigation and mitigation programs in the local systems Capital rehabilitation projects on large Regional trunk sewers Collaboration with development industry on new construction Communication and education programs Financial commitments to asset management and inflow and infiltration reduction

The Long Term Water Conservation Strategy is exceeding targets The goal of the Long Term Water Conservation Strategy is to reduce residential water use to 150 litres per person per day by 2051. In 2013, the average residential consumption was 205 litres per person per day. The program is currently surpassing targets outlined in the strategy.

1.2 Purpose and Need for the Annual Report

The purpose of this report is to provide the third annual update on progress made towards implementation of the Long Term Water Conservation Strategy (LTWCS) and the Inflow and Infiltration Reduction Strategy (I/I Reduction Strategy). Progress in achieving the goals of the strategies will be reported in Section 2, and plans for 2014 will be outlined in Section 3. This report is prepared and submitted in accordance with the requirements of Condition 8 for the SEC IEA.

1.3 Comments and Feedback Received On July 17, 2013, the MOE provided comments on the LTWCS and I/I Reduction Strategy 2012 Annual Report. Comments received expressed that York Region is appearing to make good progress on implementing Phase 1. Comments also recommended that York Region establish new residential per capita water use targets for the years 2016, 2021, 2026 and 2031 and that these new targets be included in York Regions next annual report to be submitted to the ministry in March 2014. The residential per capita five-year water use targets will be updated in 2016 after completion of an updated Strategy and in coordination with York Regions 2015 Water and Wastewater Master Plan Update commencing in 2014. This will ensure that both the Strategy and Master Plan have a coordinated approach in water demand projections and in turn allow York Region to plan infrastructure in a more sustainable, efficient and reliable manner. The updated water use targets will also be incorporated into the Condition 10 Performance Management Monitoring Program after updates to the Strategy are complete.


2 Key Program Activities and 2013 Accomplishments 2.1 Inflow and Infiltration Reduction Strategy/Program 2.1.1 Summary of program activities and accomplishments This section will outline the Inflow and Infiltration Reduction Program activities and accomplishments through 2013. Highlights of 2013 include:

An approximate I/I reduction of 1.52 million litres per day (MLD) was achieved, of which 1.34 MLD is located in the YDSS service area (3.4% of total I/I reduction target)

46 sewer mainline point repairs were made 118 manholes were relined or repaired, and hundreds more inspected. 336 km of sewer were inspected by CCTV Over 2000 laterals were inspected, and 228 repaired Over $3.84 million dollars was spent on activities related to I/I reductions A long term audit, flow, and rainfall monitoring program has begun to identify

sources and monitor inflow and infiltration over time. Development-funded investigation and remediation efforts have continued. In

Aurora, an estimated 0.28 MLD of grout-injection of infiltration sources was repaired. Additional sources of inflow and infiltration were also identified in Vaughan and other parts of Aurora

Table 2-1 outlines the I/I Reduction Program activities and accomplishments in greater detail.

Table 2-1: Inflow and Infiltration Reduction Strategy 2013 Program Activities and Accomplishments Goals/Objectives Status Estimated Completion

1. Program Component: Goals and Objectives 1) Continue to calibrate, maintain and re-assess

the outputs from the Regions all pipe hydraulic model and use calibrated model to update audit spreadsheet and refine catchment targets.

All-pipe sewage model has been developed, utilizing the InfoWorks Software An initiative to create a single shared GIS database of water and wastewater

assets for York Region and Local Area Municipalities is underway and will support the data exchange process.

As new data becomes available (through ongoing calibration sites and the long term flow monitoring program), the all pipes model will be periodically recalibrated.

Model complete and calibration ongoing

2. Program Component: Monitor and Analyze Flow 2a) Complete the installation of 220-260 audit

basin flow monitors and relocate up to 30 mini basin monitors to newly identified priority areas (estimated costs $2.5M).

UAudit Basins A long term Audit and Flow Monitoring Program has been developed for

auditing, reporting, and managing system performance. Flow and rainfall data is being collected on a long term basis will help determine inflow and infiltration volumes for audit and reporting purposes as well as determine poor system performance and remediation opportunities.

This program provides near real-time data necessary for auditing flows throughout the Region, identifying potential sources of inflow and infiltration, reductions, minimizing system risk, and maximizing capacity by fully leveraging existing infrastructure.

The program has been divided into three (3) phases: o Phase I (Planning) Audit Basin Delineation o Phase II (Developing) Monitoring Strategy and Equipment Procurement o Phase III (Executing) Monitoring Support Program

Phase II of the program was delayed as there were no flow monitors capable of supplying an HSPA modem for real time data transfer by telemetry. Since the CDMA communication network will be retired by Bell, Telus, and Rogers within 4-5 years, and the program will run for at least 20 years, York Region waited for one of the equipment vendors (ADS) to develop the technology before purchase of the meter. Phase III began with rental meters from ADS, in order to have a trial period. The continuation of the trial began at the start of Q1 2014, with installation of the new technology (HSPA modem) meters. York Region is the first municipality in the North America or Europe to have flow meters with this capability.

Total forecasted cost of the program is $5.5M spanning to 2015; approximately $3.0 M is for work performed by the Consultant and the remaining $2.5M has been budgeted for the supply of equipment. $3M will have been spent when the pilot testing phase is complete and all equipment has been ordered.

A Project Management Plan was completed in Q3 2012 Audit Basin Delineation (Phase I) was completed Q4 2012 A Site Assessment and Recommendation Report was

completed in Q1 2013 Installation of 30 test sites is completed. Final equipment

procurement and installation is expected by Q2 2014. Monitoring at 12 of the 42 sites is complete, and will continue

to be monitored in 2014 until enough wet weather data has been collected for rainfall derived inflow and infiltration (RDII) analysis.


UMini BasinsU A total of 42 mini-basin sites were monitored in 2013. Local area municipalities were consulted to identify priority areas (areas of

concern) for targeted monitoring. Priority areas included: o New development suspected of excessive inflow and infiltration, areas that

had focused remediation efforts since 2008 that had not yet been quantified, o High priorities areas previously identified, o Trunk sewer monitoring locations with capacity issues for new development

where high inflow and infiltration levels have been encountered. o Sites that would resolve wastewater generation rates

2b) Analyze post construction flow monitoring data from 2011, 2012 remediation projects and determine flow reduction achieved, update audit spreadsheet to reflect.

Post construction monitoring is complete for the 4 projects whose results were not reported in the 2013 report. The total remediation estimate is approximately 0.6 MLD.

Complete

2c) Ongoing maintenance and support of audit basin and mini basin flow monitors and data retrieval and analysis.

The Region continues to maintain its flow monitors, and stores its flow, rainfall, maintenance records, and asset tracking information via an on-line platform called FlowWorks. FlowWorks has analysis tools for inflow and infiltration calculations, and the Region is working with FlowWorks to create innovative new analysis tools.

Ongoing

2d) Complete an initial mass-balance analysis to determine base infiltration rates using water consumption and flow monitoring results to validate base and wet weather I/I rates across the YDSS and Regional system.

Some initial base infiltration studies have been started where water consumption data was available.

Ongoing

2e) Complete the wet weather flow analysis of the 2012-3 audit basins (220-260 sites) and complete detailed wet weather analysis for up to 30 min basin flow monitors.

Installation of audit basins flow meters was delayed for a necessary technology upgrade, as explained above. Wet weather analysis will be performed after Q2 2014 for the first 30 meters, and Q4 2014 for the remaining 200 flow meters, when an appropriate data sample size could yield meaningful results.

Detailed wet weather analysis was performed for approximately 20 of the 42 mini-basins being monitored in 2013. Further analysis will be performed in Q2 2014 when an appropriate data sample size can yield meaningful results.

Ongoing

3. Program Component: Investigate and Mitigate

3a) Complete the analysis of 2012 SSES investigations and establish priority remediation projects, budgetary cost estimates and define the priority of remediation projects.

The pilot project considers one catchment per local area municipality. Phase 1 is CIPP lining and Phase 2 is disconnection of sump pumps and downspouts.

Seven catchments will be part of Phase 1 (CIPP lining) of this pilot project. The units/homes per catchment are as follows: Newmarket (569), Aurora (470), Georgina (571), East Gwillimbury (588), Richmond Hill (215), Vaughan (189), and Whitchurch-Stouffville (307).

Two catchments will be part of Phase 2 (disconnection of sump pumps and downspouts) of this pilot project the units/homes per catchment as follows:

Ongoing


Markham (426), King (416). An Engineering RFP ($1,059,095.75) was released for sanitary sewer lateral

rehabilitation (CIPP lining) of private property in Q4 2013. A Communications Services RFP ($291,422.00) was released for sanitary sewer

lateral rehabilitation (CIPP lining) of private property in Q4 2013. An Engineering RFP for sump pump and downspout disconnection will be

released in Q3, 2014. There are approx. 416 homes per catchment but the exact number of cross connections is currently unknown.

The Region expects to spend approx. $10M for phase 1 and 2. Numbers are approx.: o $1.3M Engineering and Communication Services for CIPP lining o $7M in CIPP lining o $1.7M for engineering consultant and disconnection of sump pumps and

downspouts 3b) Developer Funded Inflow and Infiltration

Reduction Agreements with local municipalities and developer groups.

Four inflow and infiltration reduction tri-party agreements have been approved to date between the Region; Towns of Aurora and Richmond Hill; Cities of Markham and Vaughan; and developers; to privately fund inflow and infiltration reduction initiatives.

Developers undertaking inflow and infiltration reduction projects at their own costs in return for advanced allocation.

10 pipe segments prioritized for repair due to I/I issues were remediated by grout injection in Aurora. Estimated reduction is approximately 0.28 MLD.

Additional remediation works in Aurora have been approved by the Region and are expected to reduce additional sources of I/I. Remediation work has not yet commenced and requires further discussion with property owners.

Ongoing

3c) Complete SSES investigations at approximately 20 mini basin sites as identified in previous years flow monitoring program and analysis (estimated budget $1.0M).

Markham was engaging in SSES activities in the form of a Downspout Disconnection Program.

No Regional SSES programs outside of flow monitoring, although there will be SSES investigations commencing in 2014, starting with a smoke and dye program in Richmond Hill.

Ongoing

3d) Complete additional remediation projects based on previous years analysis and current year budget allocation.

Four trunk sewer gushers were remediated for a total benefit of approximately 0.16 MLD.

On the basis of past high priority designation from flow monitoring, the City of Markham undertook a mainline and lateral relining project which reduced I/I by approximately 0.11 MLD.

Remediation of a misaligned sewer segment in Vaughan resulted in I/I reductions of as much as 0.5 MLD.

Ongoing

3e) Establish remediation schedule for 2012-2015 resulting from completed investigation program.

Continuous investigation, operation, and maintenance programs are being carried out in each of the nine local municipalities. Reactive and corrective inspection, cleaning, and repair are being performed on first priority assets judged to be critical for rehabilitation or replacement.

Ongoing


Local maintenance and CCTV inspection programs carried out in 2013 were as follows: o Vaughan 64km of mainline a cost of $416K, and other inspection at a cost

Local initiatives this year have remediated an estimated 0.11 ML/day of I/I in the system.

Regional CCTV inspection program for 2013 included 15.13km trunk sewer. A feasibility study for the rehabilitation of 5 YDSS trunk sewers in the Town of

Aurora, the City of Markham, and the City of Vaughan, identified in the


Infrastructure Improvement Program, has been completed. The next phase for the rehabilitation of the Aurora West Collector, the Woodbridge Collector, the Maple Collector, the North Don Collector and the Leslie Collector, will be detailed design, tendering and construction. Tendering is expected Q1 2014, with project kick-off to commence Q3 2014

A three part relining project that began in 2012 and mentioned in last years report was completed in 2013.

Approximately $102M is budgeted over the next 10 years for Regional trunk sewer rehabilitation across Yorks entire system.

A Regional remediation schedule has been established. The Long Term Audit and Flow Monitoring Program will further inform future

remediation schedules.

4. Program Component: Development and Capital Projects 4a) Review OBC related building practices for new

construction and evaluate need for Ontario Building Code changes (i.e. improved materials, inspection, backwater valves.)

OBC being reviewed. Ongoing

4b) Continue to meet with contractor, developer community and suppliers/materials industry to discuss potential changes to building construction standards.

York Region has retained a consultant to transform the 2011 Sanitary Sewer System Inspection, Testing, and Acceptance Guideline, into a Regional standard/technical specification. Input from developers, local municipalities, and material vendors will be incorporated into the technical specification. Meetings have been taking place with all parties to ensure the specification is reasonable to achieve while incorporating the best in materials and methods to prevent I/I.

The most important addition to the specification is post construction flow monitoring, which will ensure future systems live up to expectations, and non-compliant extraneous flows are fixed through penalty payments.

Ongoing

5. Program Component: Financial Management 5a) If implemented, develop the financial

procedures for releasing and auditing subsidy and grant programs.

Grant programs are being funded at this time through the developer initiated programs, where the development group fixes the problem for the property owner, at their own cost, for new development allocation.

Regionally funded programs to address private side inflow and infiltration issues are being rolled out in 2014 in targeted high priority areas. Pre-remediation flow monitoring data is available for all areas, and auditing for success will be realized through the analysis of post-remediation flow monitoring data.

Ongoing

5b) Review project expenditures and revenue stream for funding the program to date and refine short and long term funding requirements to reflect known costs/benefits and future funding requirements.

Pilot flow and rainfall monitoring analysis, including detailed inspections and condition assessment approximately $5.65M expended to date.

2013 development and implementation of comprehensive audit, flow, and rainfall monitoring program approximately $5.5M. Annual operation and maintenance cost for 2013 was $850,000 and is expected to be approx. $900,000 in 2014 and

Ongoing


$850,000 in 2015. Development and implementation of audit program will further define projected

costs of the program. Approximately $102M is budgeted over the next 10 years for Regional trunk

sewer rehabilitation across Yorks entire system. 6. Program Component: Communication

6a) Develop enhanced I/I program web site and create communication materials geared towards residents that will include interactive mapping and web-TV segments describing program status, projects and priority areas.

An Inflow and Infiltration Reduction Program page has been developed on the York Region website (36TUwww.york.ca/inflowandinfiltrationU36T) which includes the following information: o What is inflow and infiltration? (with example image)

Private property example video Public property example video

o Why is inflow and infiltration a problem? o The inflow and infiltration program which outlines testing procedures for

locating I/I problems o Reducing Inflow and Infiltration o Environmental Resources link o Water and Wastewater Master Plan link o Water and Wastewater Construction link o Wastewater Collection and Treatment link

Updates to the page and public communication tools are ongoing. Direct communication with the public has been ongoing through the developer funded pilot projects. Communication plans and materials deemed acceptable to Regional and local municipal staff are being prepared and followed.

Ongoing

6b) Industry focus group will meet annually to discuss guidelines and procedures.

Industry groups were consulted in the development of the new regional technical specification for sewer installation practices, materials, and acceptance criteria.

Ongoing

6c) Review and implement social media campaigns (i.e. project status updates, Facebook, Twitter).

Project status updates occur through the Inflow and Infiltration Reduction Program website

We have been in discussions with Corporate Communications regarding Twitter and Facebook.

Ongoing

7. Program Component: Report I/I Reduction

7a) Receive annual municipal reports that describe the I/I program status and the initiatives implemented within each municipality over previous calendar year. Develop consolidated Regional report.

Data is received from the Local Area Municipalities on a yearly basis. Reporting is completed annually and included in this Report.

Continual reporting throughout the year

7b) Incorporate results from the post construction analysis of prior years remediation projects and update the audit and measure template with resulting flow reduction attainment.

Ongoing analysis and reporting is completed on flow monitoring reduction attainment.

Ongoing


7c) York Program Manager and Steering Committee to prepare and submit annual report to MOE.

The 1PstP annual report summarizing program activities and accomplishments through 2011 was submitted to the MOE on March 31, 2012.

This report serves as the fulfillment of this deliverable; a 3PrdP annual report dated March 31, 2014 summarizing program activities and accomplishments through 2013.

Complete

8. Program Component: Continuous Improvement

8a) Define and implement the required administrative structure procedures and retain staffing resources to administer private property subsidy programs such as downspout disconnection.

The Region has decided that it would be uneconomical at this time to retain internal staff for these activities. The City of Markham has begun a large scale downspout disconnection program, and development funded work in Markham is in Phase II. Private property programs in Aurora and Vaughan have been covered in high priority areas by the developer group, and remediation of roof and catch basin sources could be as much as 1.75 MLD. Activities in other municipalities will be prioritized by past flow monitoring results, and the data received through the long term flow monitoring program. Internal staff will be hired at a time where the private side activities are advancing at a pace where it would make more economic sense to run the programs in-house.

Ongoing

8b) Update Regional and municipal Design Standards to reflect outputs of the 2012 climate change models (IDF peaking factors, sewage generation, I/I allowance).

Climate change models and research are still ongoing. Ongoing

8c) Continue to enhance the inspection procedures for new construction to reflect advancements in technologies.

As outlined in 4b), York Region has retained a consultant to transform the 2011 Sanitary Sewer System Inspection, Testing, and Acceptance Guideline, into a Regional standard/technical specification. Input from developers, local municipalities, and material vendors will be incorporated into the technical specification. Meetings have been taking place with all parties to ensure the specification is reasonable to achieve while incorporating the best in materials and methods to prevent I/I.

The most important addition to the specification is post construction flow monitoring, which will ensure future systems live up to expectations, and non-compliant extraneous flows are fixed through penalty payments.

Ongoing

8d) Review program staffing requirement to reflect works completed to date and short term timeframe, develop new job descriptions and retain staffing to support the program.

Two full time permanent flow monitoring engineering positions were created to retain the institutional knowledge necessary to run flow monitoring programs and analyze the results internally, without the need for external consulting agreements.

Ongoing

8e) Integrate I/I program (asset management, finance, technology) with the Water Opportunities Act, 2010 and its Regulations.

Review of the Act is ongoing. Ongoing


2.1.2 Inflow and Infiltration Reduction Implementation Progress Implementation of the I/I Reduction Strategy began March 31, 2011, and while projects are on-going, some of the results achieved over 2013 are summarized in Table 2-2 below. The table shows the results of preliminary regression analysis of Q (flow) vs I (intensity) from flow monitoring of storm events, pre and post remediation of I/I issues and reductions estimated from modeling analysis.

2013 Inflow and Infiltration Reduction A total of 1.52 Million Litres per Day (MLD) in reductions was resolved from regression analysis and by other methods where flow monitoring was not possible or impractical. In the case of MA-041a (one of the audit basins in Markhams local municipal boundaries) and the Aurora mainline repairs, a best guess estimate for flow from the recent videos compared to baseline flow videos was used to estimate reductions. Since the videos showed active infiltration in a time not necessarily after a large storm event, it was assumed that the flow after a 25 year event would be equal to or greater than that in the video, for a period of 24 hours. In the case of AU-014a (one of the audit basins in Auroras local municipal boundaries), no pre-remediation flow data was available. Therefore the Rational Method (please refer to the Note *** underneath Table 2-2) was used to quantify the disconnected roof flows from the school. Table 2-3 below shows the original timeline for I/I Reduction goals.

Table 2-3: Target Reduction Time-Task Schedule

Inflow and Infiltration Reductions to Date 25% of the target reduction was originally slated to occur by the end of 2017. To date, the Region has achieved approximately 1.01, 4.67, 1.34 MLD reductions reported in the 2012, 2013, and current annual reports. A 7.02 total MLD reduction represents almost 17.6% of the overall 40 MLD goal, therefore the Region is on track to meet the targets in the I/I Reduction Strategy.


Public Side Rehabilitation The Regional initiatives in 2012 took place in eight catchment areas in six local municipalities through 2 contracts covering 4 catchments each. The main focus of the projects was the installation of mainline and manhole rehabilitation works of the sanitary sewer system. All of the remediation works were performed on the pubic side, with the focus placed on relining public side sewers. Four of the catchments did not have sufficient post monitoring data to be reported in last years report. Post monitoring data from the 2012 initiative was analyzed in 2013. The summary of work completed through the two contracts was as follows:

11 km of mainline rehab (full length lining) 91 point repairs 277 manholes were relined using Spectrashield technology 190 manhole surface repairs were made 46 lateral connections were repaired by grout-injection

Figure 2-2 below illustrates regression analysis results in a catchment area of one of the local municipalities as an example. The regression analysis looks at Rainfall Depth versus Rainfall Derived Inflow and Infiltration (RDII) Volume. The difference between the Post-Rehab best fit line and Pre-Rehab best fit line is the reduction in inflow and infiltration.

Figure 2-2: Post Regression Analysis Results in a Catchment in the Town of Whitchurch Stouffville


Figure 2-3 below is an example of the remediation work that is occurring as part of the manhole rehabilitation work.

Figure 2-3: Pre and Post Rehabilitation Pictures (ST-02) Ongoing Initiatives for Inflow and Infiltration Reduction The next phase for Regional rehabilitation involves private side initiatives. The project has been tendered and is expected to begin construction Q3 2014. The Regional CCTV program for 2013 included 15.13 km of trunk sewer. The next set of images is from the Wells Street High School in Aurora. The direct roof connection to the sanitary was identified by Town of Aurora staff, but was previously unreported to the Region for quantification.


Figure 2-4: Wells Street High School Location


Figure 2-5 illustrates the disconnection of the direct roof connections to the sanitary sewer.

Figure 2-5: Disconnected 6 and 4 Downspouts at Wells Street High School

Continuous investigation, operation, and maintenance programs are being carried out in each of the nine local municipalities Reactive and corrective inspection, cleaning, and repair are being performed on priority assets deemed to be critical for rehabilitation or replacement. Local municipal CCTV investigations and/or costs for 2013 were as follows: Vaughan - 64 km at a cost of $416K, and other inspection at a cost of

$164K Newmarket - 15.8 km at a cost of $48K King - 19.4 km at a cost of $56K and 50 manholes at a cost of

$2,035 Aurora - 2.95 km and 212 manholes inspected Richmond Hill - 178 km at a cost of $263K Whitchurch-Stouffville - 3.1 km at a cost of $4.5K East Gwillimbury - 38 km at a cost of $28K


Local municipal rehabilitation work carried out in 2013 included: Vaughan 10 mainline sewer spot repair and relining and 64

manhole rehabs at a cost of $287 K Newmarket 2 manholes rehabilitated at a cost of $8.5K Richmond Hill 36 spot repairs and 39 manholes sealed, $79 K spent. Whitchurch-Stouffville 13 manholes rehabilitated at a cost of $3K

Local municipalities have started lateral inspection and repair, including: Whitchurch-Stouffville 17 inspected and 3 repaired, at a cost of $4K Aurora 175 inspected Newmarket 90 inspected, 15 repaired and 2 relined, for $150 K Markham 346 laterals were inspected and 176 repaired at a cost of

$1,185K Vaughan 1057 inspected and 25 repaired at a cost of $303 K Richmond Hill 337 inspected and 8 repaired at a cost of $225 K King 60 inspected at a cost of $9,830 East Gwillimbury 1 lateral repair

Private Side Initiatives

The private initiatives are a result of tri-party agreements among the Region; the Cities of Markham and Vaughan, and the Towns of Aurora and Richmond Hill; and developers, to privately fund inflow and infiltration reduction initiatives. The I/I remediation work to date has targeted commercial roof leader disconnections, downspout disconnections and basement drain disconnections from the local sanitary sewer system; manhole remediation to prevent pick hole and cover/frame gap inflow; directly connected catch basins and/or storm catch basins and systems that are contributing flow to the sanitary through illegal cross connections; as well as sump pump connection and sanitary line cleanout sources. This year, a pilot project for pipe repair of infiltration issues was performed in Aurora. Aurora CCTV inspection videos were reviewed for infiltration issues, and 10 pipe segments with the highest potential for infiltration were chosen to be offered to the developers group for repair in return for allocation units of new development. Figure 2-6 below shows an example of an infiltration issue on Mark Street, that was fixed by spot grout injection. An estimate for the value of the repairs, measured in water savings is 0.28 MLD.


Figure 2-6: Image of Mark Street (Town of Aurora) Grout Injection Repair

An estimated 0.32 MLD in water savings through residential and commercial downspout disconnections, as well at illegally cross connected catch basin systems has also been approved for remediation in Aurora, and will commence when agreements with the property owners are attained. Further private initiative pipe infiltration remediation projects are being considered for Vaughan, Richmond Hill, and Markham in 2014. 2.1.3 On-Going Inflow and Infiltration Reduction Initiatives To date, the Region has addressed inflow and infiltration in what could be described as a reactive manner. In 2011, the Region began a process to become a municipality that searches for pro-active solutions to inflow and infiltration. The Region created a Sanitary Sewer System Inspection, Testing, and Acceptance Guideline. Over the course of 2013, the Region has begun to transform what was started in that guideline, into a technical specification for new sewer systems that will be required across all local municipalities. Consultation with the authors of best in class municipal specifications, such as the Sydney Water Leak Tight Program in Australia, was undertaken to understand what might be possible, as well as avoid or embrace their lessons learned. The most important lesson learned in the Sydney program was that flow monitoring of new development must take place, and that consequences for non-compliance with the


specification must be followed through. York Region will be incorporating a post-construction monitoring program into the technical specification. Consultation has also been undertaken by way of discussions with development groups, and vendor presentations for best materials and practices. The Region has engaged a consultant to bring together all of the relevant input from stakeholders and experiences of other municipalities, and produce recommendations on the following issues covered in the technical specification:

inspection procedures and testing specified materials allowable I/I levels resolved by flow monitoring flow monitoring analysis guideline

2.1.4 Short Term Mini-Basin Monitoring

The Region has continued targeted monitoring of 42 mini-basin sites in 2013. Monitoring included:

New development suspected of excessive inflow and infiltration (identified by local area municipal staff)

Areas that had focused remediation efforts since 2008 that had not yet been quantified

High priority areas previously identified and monitored for changes Trunk sewer monitoring locations with capacity issues for new development

where high inflow and infiltration levels have been encountered Sites that would resolve wastewater generation rates

The focused effort that began in 2013 in Kleinberg is responsible for 8 of the 42 flow monitors. The area had previously been identified as a high priority and will be covered in one of the private side pilot projects, for cure-in-place pipe (CIPP) lateral re-lining in 2014. The July 8, 2013 storm illustrated the extent of the problem, where there was a roughly estimated I/I figure of over one million litres on the first day. After quantifying and pinpointing the problems, a future sump pump disconnection program is anticipated.


2.1.5 Long-Term Audit and Flow Monitoring A long-term Audit and Flow Monitoring Program is progressing, currently between Phase II and III. The program will assess current I/I and extraneous flows in the Regional and Local systems as well as monitoring development over time. Flow and rainfall data collected on a long-term basis will help determine inflow and infiltration volumes for audit and reporting purposes as well as identify issues with system performance and remediation opportunities. In addition, the data will support the all-pipe hydraulic sewage model used for growth management, asset management, and planning purposes. This program will provide near real-time data necessary for auditing flows throughout the Region, identifying potential sources of inflow and infiltration, producing reductions, minimizing system risk, and maximizing capacity by fully leveraging existing infrastructure. The program has been divided into three (3) phases:

Phase I (Planning) Audit Basin Delineation Phase II (Developing) Monitoring Strategy and Equipment Procurement Phase III (Executing) Monitoring Support Program

The Region has entered Phase III, but some activities from Phase II are on-going. The reason for the delay was that there was no existing flow monitoring with telemetry capability that would last beyond five years from now, at the time of the request for proposal for equipment procurement. The modems installed in flow monitors at the time had code division multiple access (CDMA) technology. This technology is being retired and the new high speed packet access (HSPA) platform (3G and 4G LTE) will be available for the new flow monitoring devices moving forward. The Region has waited for the selected vendor ADS Environmental Services (ADS) to be able to provide an HSPA capable modem (so that they dont become obsolete in 5 years). Pilot period #2 of the ADS flow monitoring equipment trial, using the HSPA platform, started February 2014 with the new modem/meter, and a successful pilot will see the purchase of the remaining 200 units. Figure 2-7 on the following page shows the delineation of the audit basins and flow monitor locations in Markham.


Figure 2-7: Markham Audit Basin Delineation Example


In addition, a rain gauge network has been developed and is in the process of equipment procurement and installation. Agreements with area partners (City of Markham, Town of Richmond Hill, Lake Simcoe Region Conservation Authority, and Toronto Region Conservation Authority) has allowed York Region to leverage existing rain gauge network (see Figure 8) data into the program , and will in return share data from existing and proposed York Region stations. An additional 30 York Region rain gauges will be added to existing total stakeholder inventory of 49, to provide an approximate 2 km radius buffer around each gauge, covering the majority of the Region. Figure 2-8 shows a representation of the rain gauge cover for York Region.


Figure 2-8: Rain Gauge Network


2.2 Long Term Water Conservation Strategy 2.2.1 Summary of program activities and accomplishments There are seven major program components outlined in the LTWCS which are listed below. Table 2-4 provides a breakdown of 2013 targets, status and variance for the tactics associated with each component. URebates and Other Financial Instruments The single-family toilet rebate program, which was started in 2009, was phased out in April 2013, having met its 10-year target of 105,000 rebates well ahead of schedule. Thanks to toilet rebate programs across Ontario, high-efficiency toilets (those that flush at 4.8 litres or less) now represent approximately 50 per cent of the models available at large retailers and 90 per cent of new models being developed by manufacturers. Beginning in 2014, the Ontario Building Code requires toilets that flush with no more than 4.8 litres be installed in all new residential buildings. In 2013, York Region conducted a review and evaluation of current and proposed rebates and incentive programs to determine their effectiveness. As efficient indoor fixtures now constitute a sufficient percentage of the total marketplace, it was determined that these programs no longer make practical or fiscal sense. As such, a recommendation has been made to phase out the majority of the remaining indoor residential fixture rebate programs and develop new rebate/incentive programs to create a market transformation in residential outdoor water use. Existing rebates and incentives to be phased out in 2014:

Front-loading clothes washer replacement program for industrial, commercial and institutional (ICI) facilities

Front-loading clothes washer replacement program for multi-family residential facilities

Water efficient furnace humidifier Multi-family residential toilet rebate

The LTWCS recommended some additional program components be evaluated and implemented if cost effective. Based on results of the evaluation, the following proposed program components will not be implemented:

Hot water circulation in multi-family buildings and ICI facilities - already exists in many of these facilities.


Sub-metering subsidy in multi-family buildings - there is no evidence to suggest that sub meters in multi-family residential apartment buildings will achieve additional water savings. As well, there can be a considerable additional expense associated with installing these meters.

Plumbing retrofits on resale homes - most retailers stock only water efficient fixtures and appliances. Any new purchases over time will therefore achieve the same outcome.

UNew Development In 2013, the review and evaluation of the LEED for Multi-family High Rise and Sustainable Home Incentive Program (SHIP) was completed. As a result of this review, the LEED for Multi-family High Rise program was revised, incorporating changes in the Ontario Building Code and more rigorous requirements for inflow and infiltration. SHIP was replaced with the Sustainable Incentive Program (SIP) for grade-related residential developments. SIP offers servicing capacity assignment credits to developments achieving water conservation targets above the current Building Code and inflow and infiltration practices above current Regional requirements. Both SIP and updates to LEED were approved in principle in March 2014. Innovative and Sustainable Development Approvals Pilot Project Completed Through the Ontario Ministry of the Environments Showcasing Water Innovation initiative, York Region, in partnership with the Town of Newmarket, Lake Simcoe Region Conservation Authority (LSRCA), Toronto Region Conservation Authority (TRCA) and Mosaik Homes tested a fast-track municipal review and approvals process as a market-based incentive for water conservation and stormwater quality and quantity management practices in new construction. The project, titled Innovative and Sustainable Development Approvals (ISDA), set targets for indoor water use reduction and energy conservation above the current requirements of the Ontario Building Code (OBC) and site-level stormwater quality and quantity management beyond current standards. There were several key components of the ISDA process that proved effective and resulted in faster resolution of issues as they arose and led to more innovative design solutions. The effective elements of the ISDA project are as follows:


Establishment of performance targets placed the onus on the builder/developer to determine the design, technology, approaches and equipment needed to meet the targets and the responsibility to prove the efficacy of the solutions proffered. This approach is less prescriptive that requiring specific measures with assigned point scores as is common in municipal and third-party green building programs and represents a reduced administrative burden for municipalities.

The integrated design process (IDP) at the beginning of the project resulted in

the identification of potential issues with the development and a collective discussion and exploration of possible solutions.

The ISDA Committee comprised of key review agency core staff and consultants

meeting on a bi-monthly basis throughout the project (up to first engineering submission) kept the project moving through the process and ensured any issues or concerns were addressed expeditiously. Having key decision-making parties at the table enabled quick resolution of problems and avoided the typical back and forth that occurs between review agencies in the current process.

The final report for the ISDA project was completed in the first quarter of 2014. Next steps are currently being evaluated. Rainwater Harvesting Applications Reviewed and Gap Analysis In Progress In 2013, as per the requirements of the Long Term Water Conservation Strategy, York Region monitored municipally and Regionally owned facilities to determine the viability of rainwater harvesting applications. Data was collected via surveys and/or site visits. The monitored institutional facilities had all installed rainwater harvesting systems for non-potable water use, including flushing toilets and urinals, and vehicle washing. The monitoring showed that the majority of the rainwater harvesting systems did not have pre- or post-storage filtration or treatment, causing water quality concerns. There was apprehension about the reuse of this rainwater and potential health risks, specifically in vehicle washing applications. York Region is currently reviewing guidance documents provided by the Ministry of the Environment on rainwater harvesting and reuse to identify gaps and opportunities for incorporating water quality measures in future installations.

UGovernance and Administration To facilitate ongoing stakeholder input into the implementation of the LTWCS, a Water Conservation Advisory Committee (WCAC) was formed in 2012 and has successfully completed two terms. The Committee has provided feedback, guidance, recommendations and direction on various initiatives from the LTWCS and acted as


leaders and ambassadors. New members were recruited for the new term which began February 2014. Detailed implementation planning and reporting processes for the LTWCS were initiated in 2011 and continue as programs and initiatives are evaluated and updated based on best practices. Focus on Outdoor Water Use An Outdoor Water Conservation Plan was finalized and a new strategic direction for the Water for Tomorrow program was developed as a result. The strategic direction recognizes that the majority of water savings in the future in York Region will come from: outdoor water use industrial, commercial and institutional facilities non-revenue water reduction, and new development. The new strategic direction also recognizes the importance of targeted programs in combination with initiatives that provide the motivation for market transformation. Market transformation is a strategic process of market intervention that uses specific measures to engage business towards the use of water conserving products, practices and services. A business case and performance indicators were completed in 2013. The performance indicators, including aaverage annual residential water demands on a per capita basis, average indoor residential water demand and peak day water demands, will be used to publically report the progress of water conservation and efficiency measures in York Region on an annual basis. The first report card is expected in spring 2014. It will include an overview of the successes of the Water for Tomorrow program to date and information about future programming. An updated Annual Average Daily Demand Plan is currently being reviewed. Recommendations from this plan will be considered for incorporation into the strategic direction of the Water for Tomorrow program moving forward. UOutdoor Water Use The Regional Municipality of Peel and York Region, in partnership with Landscape Ontario, developed a Water Smart Irrigation Professionals (WSIP) certification program for irrigation contractors in Peel and York. This program will inform irrigation industry


practitioners about the importance of water efficiency in irrigation system maintenance through audit procedures and best practices. The goal of the WSIP program is to influence the marketplace, making efficient irrigation practices the new standard. This program will teach participants about auditing and scheduling methodologies and techniques used to optimize irrigation systems for ideal performance to minimize water usage. Participants will also be trained and given access to an auditing application that will decrease the time and effort required for irrigation audits. The three day course will take place in spring 2014. Unlawning Challenge Creates Water Efficient Landscapes In partnership with Toronto and Region Conservation Authority (TRCA), as part of the Sustainable Neighbourhood Retrofit Action Plan (SNAP) Eco-Landscape program, five Richmond Hill families converted their lawns to eco-landscapes in the spring of 2013. With the help of volunteers, collectively more than 150 native plants, shrubs and trees were planted in this unlawning challenge. Eco-landscaping requires less water and fertilizer and also incorporates techniques and technologies for capturing and using rain water. To determine the influence of the program within the neighbourhood, a survey which compared photos taken of the homes in the vicinity of the Front-yard Makeovers in 2012 and 2013 was conducted to identify changes. The results indicated that residents are showing interest in eco-landscaping. To assist, landscaping workshops including one on one advice from design experts are being planned for the 2014 gardening season. Utilizing Recycled Water at Recreational Facilities Investigated Staff completed a scan of splash pads in York Region and surrounding municipalities to determine how many were currently implementing water recycling. While conducting this research a concern was put forth about water quality, since there are currently no regulations around utilizing recycled water in splash pads. As such, this tactic will be further evaluated until more stringent policies for water quality are in place. York Region is currently reviewing guidance documents provided by the Ministry of the Environment on rainwater harvesting and reuse to identify gaps and opportunities for incorporating water quality measures. UPolicies and Bylaws York Region staffs previous participation in provincial sessions reviewing building code updates to advocate for the inclusion of water efficiency and water reuse contributed to changes to the Ontario Building Code, which became effective January 2014. Long Term Water Conservation Strategy and Inflow and Infiltration Reduction Strategy Annual Report 2014 30

Investigating options for full cost recovery a priority in York Region An analysis of conservation-oriented pricing took place in 2013. The analysis included two components:

An assessment of full cost recovery at the Regional and local municipal level Modelling of wholesale conservation based rate structure scenarios.

Modelling and assessments were completed in early 2014. Draft results of the potential to manage water demand using conservation-oriented wholesale and retail water rate structures were reviewed. An analysis was completed using customer water billing data provided by the local municipalities and bulk meter data provided by York Region. Six alternative rate structures were evaluated:

Uniform rate o a constant volumetric rate that is applies to all water used

Increasing block rate o the price of water increases in steps as use in the billing period increases

beyond designated thresholds Humpback rate

o a hybrid of the increasing and decreasing block rate structures Seasonal rate

o impose high volumetric charges on all water used during the peak water demand season

Excess use rate o a high volumetric charge applied to all demand during the peak water

demand season in excess of a threshold Water budget rate

o a variant of the increasing block rate structure in which the amount of water in each block is tailored to the needs of each specific customer

Based on their advantages and disadvantages, the increasing block rate structure and the seasonal rate structure are determined to be best suited for consideration for retail (local municipal) operations. All of the tested scenarios had modest to negligible impacts on customer demands; the greatest estimated reduction in average annual demand being only 2.1%. This analysis therefore indicates that very high volumetric charge rates are required to achieve even moderate reductions in water demand. A draft, high level evaluation of full cost recovery performance for York Region and local municipalities was completed and finalized in early 2014. Financial sustainability is a


prerequisite for the overall sustainability of a municipal water and sewer services division that is supported by an effective conservation strategy. The following practices were evaluated:

Individual financial performance based on current (2013) operating and capital budgets

Adherence to best practice in key areas of water supply operations including asset management, capital planning, budgeting and customer metering.

For each municipality, an evaluation was made for each indicator and a rating from excellent to poor was assigned. Preliminary results are currently being reviewed. Findings will be reported in the 2016 rate review report. URegional-Municipal Infrastructure In 2012, the International Water Association (IWA) Water Audit was completed. This audit is defined by the American Water Works Association (AWWA) as a thorough examination of the accuracy of water utility data, records, accounts policies and practices regarding the volumes of water that are moved from source to treatment to distribution to customer consumption. The results of the IWA Water Audit, which established the current levels of non-revenue water and Infrastructure Leakage Index (ILI), indicated a well-managed water distribution system with Infrastructure Leakage Index between the recommended 1.0 and 3.0 for each of the Regions nine local municipalities. The Region has developed a process for local municipalities to submit annual audits for ongoing monitoring of non-revenue water. In 2013, York Region partnered with the Cities of Markham and Vaughan to implement leak reduction programs. In an attempt to reduce the Citys infrastructure leak index (ILI), Vaughan plans to conduct a leak detection program using temporary district metered areas (DMAs) and will fix detected leaks as necessary. Markham has initiated an acoustic leak detection and correlation program that includes fixing detected leaks as necessary. To build on knowledge collected through the IWA water audit process, York Region plans to conduct a demonstration/pilot of innovative technologies used for water main flushing. Work on York Regions water and wastewater master plan update was initiated late in 2013. The impacts of water conservation on current and future demands will be incorporated into infrastructure master planning. Long Term Water Conservation Strategy and Inflow and Infiltration Reduction Strategy Annual Report 2014 32

URegional-Municipal Processes A database to store and analyse customer water consumption data from the local area municipalities was completed and tested. The information was incorporated into a GIS format to be provided to municipalities to access their data. Data from 2012 and 2013 water bills were loaded into the database. Both the total water demand by sector and the average residential per capita demand were recalculated for 2012 to ensure a consistent process is utilized for calculating these numbers throughout the reporting process of the strategy. Recommendations on water conservation and efficiency practices were provided to the Regions building and facilities design standards, specifically for landscaping requirements. York Region design standards for indoor water use already incorporate water efficient technologies and processes. UEducation and Outreach York Region continued to offer its successful education and outreach programs, including free water efficient landscaping workshops and the York Childrens Water Festival. Staff developed and piloted an in-class Grade 5 water education program. The program is expected to be launched in schools in 2014. Residential Outreach increased in 2013 Partnerships for water efficiency outreach to new Canadians were developed with TRCA and LSRCA. In 2013, staff met with CA education teams to discuss the addition of York Region specific program content in their education presentations. York Region staff provided a draft content review and input, as well as promotional and educational resources for presentations to be offered at Language Instruction for Newcomers to Canada (LINC) Centres. Nine hundred and ninety-seven new Canadians took part in 23 workshops in 2013. In 2013, York Region staff attended 56 public outreach events and provided approximately 11,400 Long Term Water Conservation Strategy and Inflow and Infiltration Reduction Strategy Annual Report 2014 33

residents with a water conservation message. Many of these events targeted diverse audiences and allowed for participant input/ideas on water conservation through electronic surveys. This information will be used to better target our future campaigns towards new initiatives, rather than promoting practices already demonstrated by residents. Further opportunities to engage a multi-cultural audience are being explored. The Water Is campaign creates an emotional connection between people and water The Water Is public campaign was launched in October 2013. This campaign is a multi-year approach to increase public awareness and education on the many values of water. The goal is to help connect residents with the physical, spiritual and natural value of water and increase awareness of what goes into providing clean, safe, reliable and affordable drinking water. This enhanced connection with water will:

Help residents understand the role of public works (water and wastewater) and the value provided through water rates

Inspire people to get involved with efforts to protect and improve the quality of groundwater, lakes and streams for now and for future generations

Empower people to become leaders in their communities and advocates of water conservation, preservation and stewardship efforts

Encourage people to improve water conservation efforts and help us reach our goal of No New Water by 2051.
