1 Introduction

1.1 Background

The Region of Peel encompasses the City of Mississauga, the City of Brampton and the Town of Caledon. The total 2011 population in the Region is approximately 1,340,000 residents and 686,000 employees1. The Region is responsible for water treatment, transmission and distribution mains, storage facilities and booster pumping stations, as well as wastewater treatment, sewers, force mains and sewage pumping stations. The Region employs the Ontario Clean Water Agency (OCWA) to operate, maintain and manage the major infrastructure of the lake-based water and wastewater systems, which are respectively referred to as the water transmission system and the wastewater trunk collection system. The Region of Peel is part of the Greater Golden Horseshoe (GGH) area situated around the western end of Lake Ontario that continues to be one of the fastest growing regions in North America. The Government of Ontario’s legislative growth plan, Places to Grow Act 2005, identifies substantial population and employment growth for the GGH to 2031. Readily available and accessible public infrastructure is essential to the viability of existing and growing communities. Infrastructure planning, land use planning and infrastructure investment require close integration to ensure efficient, safe and economically achievable solutions to provide the required water and wastewater infrastructure. To balance the needs of growth with the protection and preservation of natural, environmental and heritage resources, the Region of Peel initiated an update of its Water and Wastewater Master Plan. The 2013 Master Plan provides a review, evaluation and development of water and wastewater servicing strategies for all servicing within the lake-based systems. The lake-based systems service or will service all of Mississauga and Brampton and some areas of Caledon, including Bolton, Mayfield West and, for wastewater servicing, Caledon East. The study does not examine the groundwater-based systems or communal wastewater systems in Caledon. The 2013 Master Plan uses updated population and employment growth forecasts based on a 2031 planning horizon. The 2013 Master Plan builds on previous work undertaken as part of the 1999 Master Plan, the 2002 Master Plan Addendum and the 2007 Master Plan Update. The 2013 Master Plan is a critical component in the Region’s planning for growth and will provide the framework and vision for the water and wastewater servicing needs for the lake-based service areas of the Region to 2031 and beyond.

1.2 Master Plan Objectives

The Water and Wastewater Master Plan comprehensively documents the development, evaluation and selection of the preferred water and wastewater servicing strategies to meet the servicing needs of existing and future development to 2031.

The 2013 Master Plan evaluates the ability of existing and planned water and wastewater infrastructure in the Region of Peel to efficiently and effectively service the Region’s existing and anticipated growth, and to evaluate and develop recommended servicing strategies. The key objectives of the 2013 Master Plan are as follows:

• Review planning forecasts to 2031 and determine the impacts on servicing needs for the Region’s lake-based water and wastewater infrastructure;

• Evaluate and incorporate proposed water and wastewater infrastructure needs to 2041 and 2051; • Review the Region’s current lake-based water and wastewater servicing strategies to support the

existing servicing agreements with York Region and the City of Toronto; • Undertake a comprehensive review and analysis for both water and wastewater servicing

requirements; • Address key servicing considerations as part of the development and evaluation of servicing

strategies including: o Level of service to existing users and approved growth o Operational flexibility o Security of supply o Mitigation of impacts to natural, social and economic environments o Opportunity to meet policy, policy statements, regulations and technical criteria o Opportunity to optimize existing infrastructure and service strategies o Ensuring the strategies are cost effective

• Consider and develop sustainable servicing solutions; • Utilize updated industry trends and more detailed information from relevant Region studies and

projects to provide better capital cost estimates; • Utilize recently completed and on-going projects to update infrastructure status, capacity and cost

estimates; • Utilize the updated water and wastewater hydraulic models for the analysis of servicing

alternatives; • Establish a complete and implementable water and wastewater capital program; and • Extensive consultation with the public and stakeholders.

2 Water System Policy and Criteria

2.1 Design Criteria

The guiding principle for the design criteria is to ensure that demand projections are accurately predicted with an appropriate level of safety and risk management. This principle ensures that the infrastructure has sufficient capacity to meet the servicing requirements and that the timing of key infrastructure does not compromise operation of the facilities or impede approved and planned growth. The development of design criteria is an element that has been reviewed during each master plan update and, as a result, has evolved over the years. As such, an analysis of water design criteria was completed as part of the study to ensure that the projected water demands are accurate and reflect new trends to support decision making for the sizing and timing of future infrastructure. This analysis is included in Appendix 3C. Table 3.1 summarizes the current Region of Peel water design criteria used at a master planning level.

Table 3.1 Water design criteria for growth within the lake-based water system

Type of Development Average Day Demand Maximum Day Factor Peak Hour Factor

Residential 280 L/person/day 2.0 3.0

Employment 280 L/employee/day 1.4 3.0

Historical data demonstrate that average day flows equate to 280 L/cap/d for residential development. Based on the format of planning projections received from the Region of Peel, it is considered appropriate to utilize the employment (ICI) design criteria as a function of employees. Based on employment land criteria for lot coverage and employee density, it was determined that using an employment density of 48 employees/ha, the employment consumption rate equates to 280 L/emp/d. The rated capacity of a water treatment plant is defined as the maximum daily flow that the works is approved to treat. Water treatment capacity is based on meeting maximum day water demand requirements with an additional factor for in-facility uses such as filter backwashing. A review and sensitivity analysis of various methodologies for projecting future water demands was undertaken to determine the most appropriate methodology for the 2013 Master Plan. The approach moving forward is based on establishing a yearly starting point, calculated from historical flow data, and projecting growth demands from this starting point going forward. Projected water demands will be determined using the planning data for residential and non-residential users and applying the design criteria.




2.1.1 Water Treatment Plants

Under this approach, the design criteria will be applied to the residential and employment growth only and added to the starting point to project interval year flows. As such, the design criteria must estimate what could be consumed/generated and not necessarily what was consumed/generated. A baseline 2011 maximum day demand was calculated at each water treatment plant using historical demands as a basis for projecting future demands at the treatment plants. Equivalent per capita consumption was calculated for each year by dividing the year’s maximum day demand production by the year’s population (based on the planning data). An average per capita consumption was calculated for each plant over the last five and ten years (i.e., the 5-year and 10-year rolling averages). Going forward, the Region intends to update these rolling averages each year. The 2011 maximum day Starting Point is defined as the 2011 serviced population multiplied by the 5-year or 10-year rolling average. Residential and employment growth was then added to this baseline using the water design criteria presented in Table 3.1. The Region has historically applied the design criteria directly to the population and employment data to determine the water demand projections. The rolling average methodology will take into account yearly fluctuations between dry/warm years and wet years. Consumption will be higher in dry/warm years due to increased water usage. A sensitivity analysis was done on the projected demands to 2031 by comparing different methodologies and evaluating its impact on the 2031 demands. From the analysis it was concluded that on a Region-wide basis the 5- and 10-year averages using 275 L/cap/d and 280 L/cap/d are similar to those presently in use by the Region of Peel. This comparison confirms that the existing consumption criteria are representative of historical trends in the Region and supports validation of the criteria. As such, it is recommended that the Region continue to use the average day consumption design criteria of 280 L/cap/d for residential growth and 280 L/employee/d for employment growth, as per Table 3.1. Details of this analysis can be reviewed in Appendix 3C. The maximum day peaking factors that are currently being used by the Region are higher than those that have been observed in the last 10 years on a Region-wide basis. It was determined that the existing maximum day peaking factors, although higher than the observed trends, should be retained as they will allow for the effects of warmer-than-average summers. It is recommended that a 2011 starting point of 821.27 ML/d be used for the 2013 Master Plan, which corresponds to the 5-year rolling average methodology. A trigger point of 90 per cent of rated capacity has been used to determine when an expansion would be required. That is, an expansion is recommended when projected flows reach 90 per cent of plant capacity. If an expansion is recommended, further analysis should be conducted to confirm actual timing of the plant expansion project. The age and condition of the plant should be considered as well as the amount of storage in the system that can be used to supply maximum day demand.




2.1.2 Transmission Mains

The transmission mains are required to convey the total pumping capacity requirements of the receiving pumping station and the upper zone reservoir. This capacity is based on the component of peak hour demand for the local zone and the maximum day demand requirements for each subsequent upper zone. Theoretical transmission main capacities are estimated using capacity calculations with a reasonable allowable head loss. For larger transmission mains, a factor of 1.5 m/km of head loss is typically used. The Region of Peel full pipe hydraulic model was utilized to assess the network and to further refine transmission main capacities. Four scenarios (minimum hour, maximum day, peak hour and maximum day plus fire) were evaluated to confirm transmission main requirements. Additional criteria developed from previous studies were carried over and utilized to establish existing and future transmission main capacities. These criteria are as follows:

• Transmission mains must be capable of transferring flow with an acceptable HGL and typically below 100 psi.

• Transmission mains are typically fed from the low-lift pumps, which also directly feed the local distribution system. As such, maximum flow is based on current pumping capacity, pressure head and the need to operate these pumps with an acceptable HGL.

• Velocities within transmission mains should be maintained below 2.0 m/s. Transmission main capacity expansions are based on service level (e.g., pressure, velocity, head loss). Oversizing was considered in areas where future potential growth and build out is expected to occur. Distribution feeder main sizing is based on flow demands and pressure requirements which include maintaining pressures in the distribution system between 40 and 100 psi. Distribution feeder mains require pressures higher than 40 psi to account for hydraulic losses in the local system. Water mains that are part of the local distribution system are sized for the greater of maximum day demand plus fire or peak hour demand.

2.1.3 Water Pumping Stations

Pumping stations are rated on their firm capacity, which is defined as the capacity of the pumping station with the largest pump out of service. For each pressure zone, the west, central and east pumping stations should be able to provide peak hour demands in the immediate serviced zone and have sufficient capacity to transfer maximum day demands to the upper serviced pressure zones. Capacity expansions are triggered once the pumping station’s firm capacity reaches the required maximum day demand or peak hour demand, depending on high-lift or low-lift requirement. System head curves were developed for each set of pumps to evaluate pumping capacity.




2.1.4 Water Storage Facilities

Required storage is dictated by the ability to provide the required equalization storage, fire storage, and emergency supply to maintain a satisfactory level of service. Reservoir storage capacity at each pumping station is based on typical MOE criteria and Fire Underwriters Survey (FUS) criteria:

• Equalization storage at 25 per cent of the maximum day demand for the lower pressure zone at the reservoir’s HGL.

• Fire storage in accordance with the Standard of Municipal Fire Protection of the Canada Underwriters Association. Typically 360 L/s for 6 hours in each pressure zone based on each zone’s population.

• Emergency storage at 25 per cent of the equalization plus fire storage for the lower pressure zone at the reservoir’s HGL.

However, given that the existing Peel system typically operates under pumped supply, the reservoirs do not supply the pressure zone at the reservoir’s hydraulic grade line (HGL). Rather, they float the lower zone and control the operating pressure. As such, the typical storage capacity criteria is also cross-reference against storage volumes required for the pressure zones serviced by that pumping facility.

2.2 Service Levels

Although the focus of the Master Plan is on the water transmission system, service impacts to the local distribution system were also considered. As such, to ensure an adequate level of service, minimum water main sizes shall be as follows:

• 150-mm diameter water main for main lines in residential areas; 50-mm diameter water mains are allowed in cul-de-sacs and shall be looped back to the main line;

• 300-mm diameter water main for main lines servicing schools and high-density residential areas; and

• 300-mm diameter water main for main lines servicing industrial/ commercial/ institutional areas. As per the MOE Guidelines, the water system should be designed based on maximum day demand as well as recognize requirements for fire flows and peak hour demands. The maximum day demand is typically referenced as a maximum day factor above the average day demand. A minimum operating pressure of 40 psi (275 kPa) and a maximum operating pressure of 100 psi (690 kPa) shall be maintained within the distribution system under maximum day demand and a minimum operating pressure of 40 psi shall be maintained under peak hour demand. Under fire flow conditions, it is allowable for pressures to drop to a minimum of 20 psi (140 kPa).

2.3 Costing Methodology

Preliminary unit rates for linear and vertical infrastructure were discussed and agreed upon by the project team. These costs are based on 2013 dollars and take into consideration local prices of labour and local




availability of materials wherever possible. Construction industry indices were referenced in the development of these unit costs. Estimates were favourably compared to costs of recent capital projects to support validation of the unit rates.

2.3.1 Unit Rates

The proposed unit rates will be used as a basis to develop estimates for each of the projects identified in the 2013 Master Plan. The rates were initially developed as part of the Quick Start program at the beginning of the master plan process.2 As the 2013 Master Plan focuses on trunk water and wastewater infrastructure, the emphasis of the peer review was on the unit rates for this size of infrastructure. A peer review of linear unit rates was conducted as part of the 2013 Master Plan. The unit rates used in the Quick Start program were provided to Estimating Services Incorporated (ESI) for review. The focus of the review was to determine whether the 2013 Master Plan unit rates provided a sound basis for project estimates. As part of the review, ESI developed their own unit rates for comparison based on consultation with suppliers as well as recent project experience. The ESI and Quick Start unit rates were compared to determine if the Quick Start values fell within a reasonable range of the ESI values. It is not expected that the rates should be identical, as ESI rates are based on May 2012 construction conditions and are not sufficiently conservative for a master planning study; whereas the Quick Start unit rates were developed to represent general unit rates in 2011 for master planning purposes. The results of the peer review were used to adjust the Quick Start unit rates for use in the 2013 Master Plan. The following adjustments were made: The pipe supply rates for force mains and water mains were increased by 20 per cent. Where appropriate, the 30 per cent factor was applied in the individual project costing sheets. A minimum installation cost of $40/metre was used to prevent unrealistically low installation costs. The formulae used to calculate excavation volume were adjusted. For the 5-metre deep wastewater pipe, a 5-metre deep trench box was assumed (i.e., the excavated volume was calculated as depth x width or 5 metre x width, per metre of pipe). Due to relatively negligible inflation between 2012 and 2013, an effective inflation rate of 0% was used to adjust the 2012 unit rates to 2013 dollars. Unit rates have changed significantly since the 2007 Master Plan. Factors that have contributed to the change in unit rates include inflation, the fact that pipe pricing is considerably higher now, excavation and granular costs have increased, and increasing fuel prices have had effects over several areas. The existing unit rates were revised based on the peer review process and are considered appropriate for master planning purposes. The unit rates are within the range of costs to be expected on competitively tendered jobs in the Region of Peel, accounting for add-ons that may be applied on a project specific basis (e.g., for urban areas, difficult construction conditions, and project-specific considerations). 2 Memorandum - Peel Quick Start. AECOM, August 2011.




2.3.2 Operation and Maintenance Costs

Operation and maintenance (O&M) costs were considered qualitatively at every stage of the evaluation process. For example, where one strategy requires more pumping stations relative to other strategies, that strategy will score less favourable under the financial impact category due to higher maintenance and operating costs inherent with the new facilities.

2.3.3 Final Project Costs

Based on the linear and vertical unit rates, detailed costing sheets were developed to support the financial evaluation for each alternative alignment, storage facility, pumping station, and water or wastewater treatment project. This costing sheet considers base costs, including: construction, geo-technical, property requirements, permit and approval requirement, overhead and project contingencies.




3 Existing Water Transmission System

3.1 Existing Infrastructure

The Region of Peel’s lake-based water transmission system services the City of Mississauga, much of the City of Brampton, and parts of the Town of Caledon. The system consists of two Lake Ontario-based water treatment plants (the Lakeview WTP and the Lorne Park WTP), transmission mains, pumping stations, reservoirs and elevated tanks that deliver water to customers through seven pressure zones separated by approximately 30-metre intervals of elevation. The lake-based water transmission system consists of three main trunk systems: west, central and east. The existing transmission facilities are summarized in Table 3.2. Separate from the water transmission system, the water distribution system conveys treated water from the water transmission facilities to the customers. With the exception of east-west sub-transmission, the water distribution system is not included in the 2013 Master Plan for the lake-based system. The Region of Peel also maintains four municipal groundwater systems servicing rural communities in the Town of Caledon. These municipal groundwater systems are not included in the 2013 Master Plan for the lake-based system.

The Lorne Park WTP provides water supply for the west transmission system and the Lakeview WTP provides water supply for the central and east transmission systems. Although the water distribution system is interconnected throughout each pressure zone, the approximate service boundary between the west and central systems is McLaughlin Road and the approximate service boundary between the central and east systems is Airport Road.

3.1.1.1 Lakeview Water Treatment Plant

The Lakeview WTP is located in southeast Mississauga, east of Cawthra Road and south of Lakeshore Road East, at the south end of East Avenue. The Lakeview WTP is a conventional water treatment plant with an advanced treatment train consisting of ozone, biologically activated carbon (BAC) contactors and membrane filtration. The site area is approximately 27 hectares (67 acres), including water lots, of which approximately 14 hectares (35 acres) is presently being used for the water treatment plant. The potential ultimate site capacity is approximately 1150 ML/d under maximum day conditions and conventional technologies. The Lakeview WTP expansion schedule is primarily based on growth in east Peel and water demand for York Region. The Lakeview WTP raw water intake is a 2550-mm diameter pipe extending 2,000 metres into Lake Ontario. The pipe has two intake cribs that feed a common intake pipe. Overall, the intake has a net capacity of 1,150 ML/d.

3.1.1.2 Lorne Park Water Treatment Plant

The Lorne Park WTP is located in southwest Mississauga, east of Southdown Road and south of Lakeshore Road West within Jack Darling Memorial Park. The Lorne Park WTP is a conventional water treatment plant. The Lorne Park WTP is largely underground to minimize the visual impact on the park setting. The potential ultimate site capacity is approximately 500 ML/d under maximum day conditions and conventional technologies. The Lorne Park WTP expansion schedule is primarily required based on growth in west Peel. The 2002 Master Plan Addendum recommended expansion of the Lorne Park WTP capacity from 347 ML/d to 500 ML/d by 2013. Additional review under the 2007 Master Plan led to the concept of expanding the plant capacity through internal retrofitting. Following preliminary and detailed design, the following construction contracts were undertaken:

• Construction of a new pumping station and two sewage pumping stations within the same site (completed in 2011);

• Construction of a new pipe connection to the existing intake (completed in 2011); • Construction involving the new treatment processes, including the membrane and ultraviolet (UV)

disinfection processes (new building expansions and Milestone 1 for 210 ML/d membrane and UV disinfection completed in 2011 with the balance of the membranes completed in 2012).

3.2 Hydraulic Water Model

The Region maintains an InfoWater hydraulic model of its water distribution system. The water model used for the 2013 Master Plan was last updated based on the GIS data received on May 31, 2011. The model update process includes the following main steps:

1. GIS data review; 2. Model update; 3. Model QA/QC; and 4. Demand allocation.

Subsequent to the update of the hydraulic model, the model was calibrated to confirm the hydraulic model accuracy. Hydraulic model calibration is the process of testing and adjusting the model to ensure that model results bear reasonably close comparison to actual performance of the water distribution system over a range of operating conditions. Calibration is mandatory prior to use of the model for any capital works decision-making analysis, as well as further applications of the model such as water quality, operations or energy management modelling. The benefits of calibration include discovering and correcting discrepancies in the model data and, occasionally, identification of problems in the field.

Model calibration essentially encompasses all aspects of the model development and field data collection process. The process makes extensive use of the field program results as well as review of Region records and field confirmation. This calibrated model was used as part of the 2013 Master Plan analysis.

3.3 Water Servicing Flow Schematics

To evaluate the water servicing requirements including immediate pressure zone demands as well as capacity required to service subsequent pressure zones, water servicing flow schematics were developed for each of the planning intervals, 2012, 2016, 2021, 2026, and 2031. Storage schematics for 2031 and 2051 were also developed to show storage surplus or deficit in each pressure zone. The water servicing flow schematics and storage schematics are included in Appendix 3E.

4 Assessment of the Existing and Future Water Infrastructure

4.1 Opportunities and Constraints

As part of the Master Plan, it is important to perform an assessment of the factors that provide opportunities for developing and expanding the water system to meet growing demands as well as identifying existing constraints. In the Region of Peel the following opportunities and constraints for the water system were identified:


• The Lakeview Water Treatment Plant is currently being upgraded to a capacity of 1150 ML/d. Based on Places to Grow planning forecasts, this expansion is projected to provide sufficient capacity to service 2031 demands. The 2013 Master Plan will confirm long-term site capacity and future expansion requirements.

• The Lorne Park Water Treatment Plant is currently being upgraded to a capacity of 500 ML/d, which would be sufficient capacity to service 2031 demands, based on Places to Grow planning forecast. The 2013 Master Plan will confirm long-term site capacity and future expansion requirements.

• Additional capacity will be required to support additional demands in the Mississauga City Centre (MCC).


• There is an opportunity to optimize east-west transfers with distribution and pumping for improved level of service and security of supply.

• Additional transfer capacity is required from the Streetsville Pumping Station to the Meadowvale North Reservoir as well as from the Herridge Pumping Station to the Streetsville Reservoir.

4.1.3 Pumping Stations and Storage Facilities

• There is space for expansion of pumping capacity in the North Brampton Reservoir and Pumping Station facility, however there is no space to expand the reservoir.

• Additional storage capacity may be required north of Mayfield Road to service the upper pressure zones.

• Water is supplied to York Region through the Airport Road Pumping Station. • There is sufficient space at the West Brampton Reservoir and Pumping Station to expand both

pumping and storage capacity. • There is sufficient space at the Beckett Sproule Reservoir and Pumping Station to expand both

pumping and storage capacity. • There is sufficient space at the Silverthorn Reservoir and Pumping Station to expand the reservoir.



March 31, 2014

Page 22

4.1.4 Growth Opportunities

• The recent North Bolton Elevated Tank Class EA study in the Bolton Area should be incorporated into the updated Master Plan water servicing strategy.

• Significant additional growth could occur in the areas north of Mayfield Road post-2031. The 2013 Master Plan will determine the potential impact of this growth on infrastructure.

• A servicing strategy for population and employment growth potential in the Mayfield West development area will be incorporated into the 2013 Master Plan.

• Significant residential and employment growth is projected in northeast and northwest Brampton to 2031.

• The Hurontario Corridor is targeted for intensification. Results of the intensification analysis will be incorporated into the 2013 Master Plan.

4.2 Water Demand Requirements

Water demand requirements were developed for each system to identify existing and potential future supply deficiencies. Based on the planning projections, maximum day demand projections for the Region’s lake-based system, including York flows, are summarized in Table 3.4.

Table 3.4 Forecasts of maximum day demands for the lake-based system (ML/d)

4.3 Hydraulic Analysis


The 2013 Master Plan analyzed the projected growth demand within each water treatment plant service area to ensure that the facility expansions and pressure zone shifting strategy were aligned adequately with growth. Figure 3.3 and Figure 3.4 show projected demands for each plant based on their pressure zone service area. The current plant capacities are also represented. There is sufficient total treatment capacity at each plant to service the Region’s needs to 2031. However, when considering the projections for each individual plant and their service area, 90 per cent of the Lakeview WTP capacity is reached before 2031, but it will not reach 100 per cent of its capacity until post-2031. The Lorne Park WTP will reach 84 per cent of its capacity by 2031.

The InfoWater hydraulic model, in combination with the water system schematics were used to evaluate the water system’s transmission capacity. System head curves were developed for each pumping facility to evaluate the ability of the transmission mains to move water north through the system and assist in identifying constraints. Generally, existing transmission mains have sufficient capacity to move water to the next pumping station under maximum day conditions. The requirements identified under the 2007 Master Plan continue to be valid. The following transmission mains were identified as not being able to supply future demands. Herridge Pumping Station to the Streetsville Reservoir (WT2S) The existing Pressure Zone 2 transmission mains from the Herridge Pumping Station to the Streetsville Reservoir will reach their capacity by 2026. An extension of existing the 2100-mm transmission main from the Lorne Park WTP to the discharge side of the Herridge Pumping Station will be required to the Streetsville Reservoir. Streetsville Pumping Station to the Meadowvale North Reservoir (WT3) The existing Pressure Zone 3 transmission mains from the Streetsville Pumping Station to the Meadowvale North Reservoir will reach their capacity by 2021. Twinning of the existing transmission mains with a new 1200-mm transmission main will be required. Beckett Sproule Pumping Station to the East Brampton Reservoir (ET4) The existing Pressure Zone 4 transmission main from the Beckett Sproule Pumping Station to the East Brampton Reservoir will reach its capacity by 2021. Twinning of the existing transmission main with a new 1500-mm transmission main will be required.

4.3.3 Water Pumping Stations

Assessment of pumping capacity was based on the ability to provide the firm capacity to meet the required demands in the system. The hydraulic analysis conducted in the 2013 Master Plan confirmed the need for pumping station expansions or new pumping stations that will be required within the 2031 timeframe as identified in the 2007 Master Plan. As part of the analysis, system head curves were developed for every pumping station to be able to identify constraints that limit the facility’s actual pumping capacity (these graphs are shown in Appendix 3E). Table 3.5 shows the lake-based pumping station requirements every five years to meet the projected demands.



March 31, 2014

Page 25

Table 3.5 Pumping station requirements for the lake-based system (ML/d)

The current capacities at some of the pumping stations may not be sufficient to meet 2031 water demand requirements. Water system schematics as well as hydraulic modeling to create system head curves were used to assess the water pumping station requirements. The calculated “starting point” along with growth layered onto each pressure zone and calculated pumping ratios generated the estimated yearly pumping requirements to 2031. Based on the analysis, the following pumping deficiencies were identified.

Lakeview Pumping Station Expansions to the Zone 1 and Zone 2 high-lift pumps, identified in the 2007 Master Plan, continue to be a requirement. Beckett Sproule Pumping Station There is sufficient Zone 4 and Zone 5 pumping capacity at this facility after the recent upgrades. Expansion of the Airport Transfer pumping was identified and planned based on the 2007 Master Plan and should be maintained. North Brampton Pumping Station Expansion of the Zone 6 pumping was identified in the 2007 Master Plan and continues to be a requirement. The firm capacity of this station will be exceeded by 2021 when the Victoria Reservoir is commissioned. There are currently two additional pump bays available. The Zone 7 pumping requires an additional 10 ML/d by 2031. It is recommended that a pump performance review be undertaken prior to moving forward with an expansion. Herridge Pumping Station There is sufficient Zone 2 pumping capacity at this facility to meet 2031 needs. There are three pump bays available for future capacity expansion. Streetsville Pumping Station Currently, there is a future Zone 3 72 ML/d pump being designed, and there are three pump bays available for future expansion. Upgrades to the Zone 4 pumps are currently underway, one pump is being decommissioned, two 68ML/d pumps are being designed and there are two additional pump bays available for future expansion. West Brampton Pumping Station Expansion of the Zone 5 pumping was identified in the 2007 Master Plan and continues to be a requirement. The station requires an additional 37 ML/d by 2031 to meet future demands. One additional pump bay is available for future expansion.

4.3.4 Water Storage

Water system schematics and Peel’s water hydraulic model was utilized to assess future storage requirements. Storage deficiencies were identified and can be seen in Figure 3.5.

4.3.5 Intensification

An analysis was completed to evaluate the impacts of meeting intensification targets in Mississauga and Brampton. Impacts to the transmission system were identified as part of the master plan process; however, impacts to the sub-transmission and distribution infrastructure were also analysed.

5 Evaluation of Concepts and Strategies

The identification and evaluation of servicing options is a critical component of the master planning process because it enables a comprehensive review of a reasonable range of alternatives while documenting the process in a transparent manner. The evaluation process that has been undertaken is described in the following sections.

5.1 Objectives

The Region intends the 2013 Master Plan to meet the Approach 2 requirements under the Municipal Engineers Association (MEA) Class EA process. Under Approach 2, a Master Plan Report is prepared at the conclusion of Phases 1 and 2 of the Class EA process. This approach allows for all Schedule A, A+ and select Schedule B projects identified in the Master Plan to move forward to implementation. To achieve this objective, systematic evaluation and documentation is required to support the Schedule B Class EA requirements along with any applicable review agency commitments prior to implementation. Any Schedule C projects identified will also require supporting information and decision making to proceed onto separate studies and continue to Phases 3 and 4 of the Class EA process. The proposed evaluation approach described herein has been designed to ensure a logical and transparent process that can document the evaluation and decision making that will ultimately develop a capital program that is defensible. Sustainability principles will also be considered in the development of the 2013 Master Plan, and will be integrated within the five-point evaluation, such as: 1. making best use of existing infrastructure; 2. minimizing the cost of new infrastructure; 3. considering operation and maintenance costs to ensure financial sustainability; 4. ensuring the long term reliability and security of the water and wastewater systems; and 5. performing financial evaluation including lifecycle costing.

5.2 Description of the Evaluation Process

Opportunities and constraints for each system were identified at the outset of the study and are used as a starting point for identifying conceptual servicing options. The evaluation process progresses from high-level concepts to more detailed servicing strategies and, where applicable, to detailed evaluation of individual alignments or sites. The progression from a high-level to an increasing level of detail allows for a more efficient process, as it screens out non-feasible and unfavourable servicing concepts before they are carried forward for detailed evaluation. The complete process of identifying, evaluating, and selecting a preferred servicing option is shown in Figure 3.6.

5.3 Evaluation Criteria

Detailed evaluation matrices supporting the evaluation of alternative servicing concepts, strategies, and alignments or sites are provided. Maps to accompany alternative servicing concepts, strategies, and alignments or sites are included in Appendix 3D. As described in Section 5.2, servicing strategies and appropriate alignments and sites are subject to a five-point evaluation, which includes five major areas of impact: environmental, technical, socio/cultural, financial, and legal/jurisdictional. The five-point evaluation criteria and their associated impacts are described in Table 3.6.

5.4 Servicing Concepts

At a conceptual level, each system was considered in isolation with the list of opportunities, issues, and constraints in mind, both within the larger Regional context and at the localized service level. As shown in Figure 3.6, a list of servicing concepts to address existing and future servicing issues was considered



March 31, 2014

Page 32

at a high level, weighing the advantages and disadvantages of each concept. The initial, strategic concepts (red box) will be evaluated simplistically, with advantages and disadvantages listed. A score based on an overall rating of high, medium, or low was assigned to each concept based on this preliminary evaluation, where high is more favourable. Based on the scoring, concepts were either screened out or carried forward in combination for further evaluation. The concepts evaluated are listed as follows and the description and evaluation of these concepts can be found in Appendix 3D. 1. Do Nothing 2. Limit Community Growth 3. 2007 Master Plan 4. New Stream-Based or Groundwater-Based Water Treatment Plant 5. New Lake-Based Water Treatment Plant 6. Efficiency

5.5 Servicing Strategies

Combinations of the concepts carried forward formed various strategies (orange box in Figure 3.6) that are generally considered complete solutions. The descriptions of the strategies are relatively detailed and thus offer greater scope for more detailed evaluation. At this stage, each strategy is subjected to a five-point evaluation, which includes environmental, technical, socio/cultural, financial, and legal/jurisdictional impacts. Each strategy is scored based on the positive and negative aspects identified for each impact category using a rating system of high, medium and low, where high is more favourable. The strategy with the highest overall score was selected as preferred. Seven water servicing strategies were developed and evaluated with this process. The water servicing strategies are described as follows: Strategy 1 – Planned East-Central-West Boundaries:

• Build off planned 2031 infrastructure as per the 2007 Master Plan while maintaining the planned East-Central-West servicing boundary;

• Expand transmission, storage and pumping as outlined in the 2007 Master Plan;

• Add pumping and transmission capacity to match the planned East-Central-West boundary; and

• Continue to implement the Region’s water conservation program.

Strategy 2 – Hydraulic East-Central-West Boundaries:

• Build off planned 2031 infrastructure as per the 2007 Master Plan while shifting the planned East-Central-West servicing boundary to match system hydraulics;

• Expand transmission, storage and pumping as outlined in the 2007 Master Plan;

• Allow intra-zone boundaries to be defined by hydraulics within the system and adjust the planning boundaries accordingly; and




March 31, 2014

Page 33

Strategy 3 – Planned/Hydraulic East-Central-West Boundaries:

• Build off planned 2031 infrastructure as per the 2007 Master Plan while shifting the planned East-Central-West servicing boundary to match system hydraulics in selected pressure zones;

• Allow servicing of some existing pressure zones to be dictated by existing hydraulics within the zone;

• Add pumping and transmission in selected pressure zones to shift the East-Central-West boundaries to closely match the planned boundary and maximize the use of existing infrastructure; and


Strategy 4 – New Stream-Based Water Treatment Plant:

• Build off a modified version of the planned 2031 infrastructure as per the 2007 Master Plan and construct a new stream-based water treatment plant to service growth in the upper pressure zones;

• Provide supply to the northeast pressure zones from the new stream-based water treatment plant;

• Expand transmission, storage and pumping in the West Transmission System as per the 2007 Master Plan; and

• Potential opportunity to defer or reduce upgrades in the Central Transmission System.

Strategy 5 – New Groundwater-Based Water Treatment Plant:

• Build off a modified version of the planned 2031 infrastructure as per the 2007 Master Plan and construct a new groundwater-based water treatment plant to service growth in Brampton;

• Provide supply to the northeast pressure zones from the new groundwater-based water treatment plant;

• Expand transmission, storage and pumping in the West Transmission System as per the 2007 Master Plan; and

• Potential opportunity to defer or reduce upgrades in the Central Transmission System.

Strategy 6 – New Lake-Based Water Treatment Plant near the Shoreline:

• Build off a modified version of the planned 2031 infrastructure as per the 2007 Master Plan and construct a new lake-based water treatment plant near the Lake Ontario shoreline;

• Additional supply to the transmission and distribution system from a new lake-based water treatment plant; and

• Expand transmission, storage and pumping as per the 2007 Master Plan.



March 31, 2014

Page 34

Strategy 7 – New Lake-Based Water Treatment Plant within the Region of Peel:

• Build off a modified version of the planned 2031 infrastructure as per the 2007 Master Plan and construct a new lake-based water treatment plant within the Region of Peel;

• Additional supply to the transmission and distribution system from the new lake-based water treatment plant;

• Expand transmission, storage and pumping as outlined in the 2007 Master Plan; and

• New extended raw water intake required.

The seven strategies were evaluated using the five-point evaluation criteria and one was selected as the preferred water servicing strategy. The evaluation of water servicing strategies is shown in Appendix 3D.

5.6 Alignments and Sites

The preferred strategy was dissected into component parts, such as water mains, pumping stations and storage facilities. Where required, individual alignments and alternative facility sites were identified and, where appropriate under the Class EA process, subjected to a siting and alignment evaluation process (green box in Figure 3.6). This evaluation uses the same five-point evaluation criteria and rating system to score the alternative alignments and sites. The alignments and sites with the highest overall scores were selected as preferred.

6 Preferred Water Servicing Strategy

This section summarizes the preferred Water Servicing Strategy for the Region of Peel to satisfy growth to 2031. In addition, this section includes capital costing and alignment and site evaluations for the preferred solution.

6.1 Preferred Servicing Strategy

As described in Section 5, each strategy was evaluated using the five-point evaluation criteria, which include considerations for environmental, technical, socio-cultural, financial and legal-jurisdictional factors. The strategy with the highest overall score from the five-point short list evaluation matrix was Strategy 2. Key benefits of the preferred Water Servicing Strategy include: 1. Maximizing the use of existing water transmission mains and treatment infrastructure as it builds off

existing and planned transmission and distribution infrastructure; 2. Minimizes environmental crossings for west-to-east transfers as well as reduced transmission costs

with no west-to-east transfers; 3. Does not require the construction of a new water treatment plant within the 2031 horizon; and 4. Opportunity to leverage the existing water servicing strategy with optimization of system hydraulics.

Key projects within this strategy include: 1. Streetsville, Meadowvale North and East Brampton Transmission Main twinning; 2. Pumping station upgrades at Lakeview Zones 1 and 2, Herridge Zone 2, Streetsville Zones 3 and 4,

West Brampton Zones 5 and 6, North Brampton Zones 6 and 7 and the Beckett Sproule Transfer Station;

3. New North Bolton Elevated Tank; 4. Extension of the distribution system in northwest Brampton and northeast Brampton to service new

growth areas; and 5. Extension of the distribution system in Bolton. In addition to the key capital projects, several smaller upgrades are included within the strategy to address local capacity constraints within the system. The preferred Water Servicing Strategy can be seen in Figure 3.14. Each individual project is listed with its respective estimated capital cost in Table 3.7.

6.2 Capital Program for the Preferred Water Servicing Strategy

The five-point evaluation process considered high-level analysis of the financial impacts of each strategy to provide perspective on the capital cost implications of the major capital works associated with each strategy. The strategies were compared against each other to determine the relative sub-score. Once the preferred strategy was selected, a detailed capital program was established, based on the methodology outlined in Section 5. For the purposes of the Master Plan, a project numbering system was created for both water and wastewater projects. Each Master Plan project number is comprised of three elements, separated by a hyphen “-“:

1. Water (“W”) or Wastewater (“WW”) Identifier

2. Project Type Code • “D” –Distribution Main • “ST” –Sub-Transmission Main • “T” –Transmission Main • “P” –Pumping Station • “S” – Storage Facility (Reservoir or Elevated Tank) • “TR” – Water Treatment Plant

3. Unique, 3-Digit Project Number (e.g., “021”)

For example, the Water Master Plan project number for the Beckett Sproule Pumping Station Expansion is “W-P-064”. Depending on the size and scope of a particular project, the Capital Program has separated project components into cost categories such as environmental assessment (EA), design and construction. The capital program for the preferred Water Servicing Strategy is shown in Table 3.7.

7 York Region Water Servicing Strategy

The York water requirements were supplied from York Region and defined as Schedule C of the York-Peel Water Servicing Agreement. They are a key component of the long-term water supply and servicing requirements for the Region of Peel. They are generally reflected in the water supply requirements for the Central and East Transmission Systems. The 2031 water supply requirement for York Region is 388 ML/d.

7.1 York-Peel water servicing agreement

The maximum day demands as per the York-Peel Servicing Agreement are shown in Figure 3.15.

Figure 3.15 Maximum day demands as per the York-Peel water servicing agreement

Water supplied to York Region is treated at the Lakeview Water Treatment Plant and pumped north through the Central Transmission System. It is then transferred to the East Transmission System through the Beckett Sproule Transfer Pumping Station and then pumped to York Region from the Airport Road Pumping Station. Currently, this station has two installed pumps at a capacity of 277 ML/d and has a planned expansion to take the capacity to meet York’s demand requirement as per the Agreement.

Page 55

7.2 Impact on Water Infrastructure


The York water demand requirement is supplied by the Lakeview WTP. This facility has sufficient capacity to service the required maximum day water demands to 2031, including York demands as per the Agreement. Beyond 2031, expansion of one or both of the water treatment plants could be required.

7.2.2 Pumping Stations

The 2007 Master Plan identified upgrades at the Beckett Sproule and Airport Road Reservoirs and Pumping Stations to meet York’s demand requirements. Some of these upgrades have been implemented while others continue to be valid and are included in the capital program.


York demands are supplied by the Central and East Transmission Systems. A major required upgrade is the Hanlan Transmission Main which is currently under construction. This transmission main will service growth in Peel as well as York water demand requirements.

8 Intensification and Post-2031 Growth

8.1 2031 Intensification

Intensification is currently underway in many parts of the Region of Peel. Future intensification is reflected in the Region’s detailed growth projections within the 2031 planning horizon. The focus of this intensification is within three corridors: the Mississauga City Centre (MCC), the Hurontario Corridor and the Queen Street Corridor in Brampton.

8.1.1 Mississauga City Centre

The Mississauga City Centre (MCC) is bounded by Central Parkway to the south, Highway 403 to the north, the Cooksville Creek to the east and Grand Park Drive to the west. The area occupies approximately 26 hectares. Current water servicing to this area is through several trunk water mains from the Silverthorn Pumping Station and the Hanlan Pumping Station. The majority of the MCC is located within Pressure Zone 3C, with a small area southeast of Hurontario Street.and Burnhamthorpe Road located within Pressure Zone 2C. The local service area is serviced by a looped system of 300-mm and 400-mm water mains that generally follow the road alignments. Growth within the MCC from 2013 to 2031 is estimated to be approximately 16,497 people and 8,583 jobs.

8.1.2 Hurontario Corridor

The Hurontario Corridor runs along Hurontario Street from south of Lakeshore Road in Mississauga to Queen Street in Brampton and is anticipated to be the focus of intensification within the Region of Peel. The area occupies approximately 568 hectares. The Hurontario Corridor is serviced from the Lakeview Water Treatment Plant through the Central Transmission System covering Pressure Zones 1C though 5C. Growth within the Hurontario Corridor from 2013 to 2031 is estimated to be approximately 27,674 people and 19,990 jobs.

8.1.3 Brampton Queen Street Corridor

The Brampton Queen Street Corridor runs along Queen Street in Brampton from McLaughlin Road to Highway 50. The Queen Street Corridor occupies a large area spread from east to west and is mostly contained within Pressure Zone 5C, with some eastern extents crossing into Pressure Zones 5E and 4E. The corridor is predominantly serviced from the Beckett Sproule Pumping Station and the East Brampton Pumping Station. The area is directly serviced through several distribution mains ranging from 300-mm to 600-mm.



March 31, 2014

Page 57

Growth within the Queen Street Corridor from 2013 to 2031 is estimated to be approximately 32,630 people and 22,240 jobs.

8.1.4 2031 Intensification Servicing

In addition to the projects that make up the preferred Water Servicing Strategy outlined in Section 6, the 2013 Master Plan recommends several specific projects to service growth within the intensification areas. Upgrades to the Beckett Sproule, East Brampton, Hanlan and Silverthorn Pumping Stations, several smaller water main upgrades downstream of the MCC and wastewater treatment upgrades all service 2031 intensification growth and will make up part of the longer term strategy for intensification growth within these areas. There are a few storage expansions that may also be required. The Lakeview Water Treatment Plant will require upgrades to the intake as well as Pressure Zone 2C pumping. These projects, coupled with the 2031 Water Servicing Strategy, give the Region the ability to service the 2031 growth, but also support long term servicing in these areas.

8.2 Post-2031 Vision

The 2013 Master Plan puts forward a comprehensive trunk-level water and wastewater plan to service growth within the Region of Peel to the approved Places to Grow 2031 forecast. While the approved urban boundary and growth targets are to 2031, the Master Plan also considered implications of potential post-2031 growth on the system. The preferred Water Servicing Strategy addresses the growth needs to 2031 and also establishes flexibility within the system to implement a post-2031 strategy, once the long-term targets are confirmed and approved. Post-2031 growth is anticipated at two levels: intensification and greenfield growth. It is expected that greenfield growth will most likely occur in new pressure zones and will require new pumping and storage facilities.

8.2.1 Post-2031 Intensification

While intensification is presently occurring within Peel and will continue to 2031, potential post-2031 intensification growth was investigated within the major intensification areas outlined in the previous sections. Since the post-2031 growth projections are not finalized at this time, only a high level servicing investigation of intensification growth was completed. Detailed analysis of water infrastructure capacity and constraints has not yet been undertaken for the intensification areas. However, the 2031 Water Servicing Strategy establishes flexibility within the water distribution system and will support a longer-term post-2031 strategy within the intensification areas.



March 31, 2014

Page 58

Post-2031 intensification growth within the MCC, Hurontario Corridor and the Brampton Queen Street Corridor will require a strategy that focuses not only on local upgrades but also on the transmission, pumping and storage capacities as well as upgrades to the existing water treatment plants or investigate other water source options. Depending on location, timing and scale and the significance of post-2031 growth, the east-central-west zone boundary strategy will need to be revisited and analyzed in greater detail. It is understood that there are limitations to pumping, transmission and storage capacity, treatment capacity and treatment facility site capacity as well as several constructability issues within the existing water system. All of these factors must be considered when developing a post-2031 water servicing strategy.

8.2.2 Post-2031 Greenfield

The majority of both residential and employment development within Peel throughout the past several years has taken place within greenfield growth areas. The built boundaries of Mississauga and Brampton have continued to extend to the north forcing both the water and wastewater infrastructure to extend along with them. This has necessitated the construction of sewer extensions through the growth areas as well as increasing capacity (twining in some cases) in the downstream sections of sanitary trunk sewers. Throughout this growth, the Region of Peel has implemented strategic oversizing of trunk infrastructure to support development outside of past planning horizons. Though 2031 is the planning horizon for the 2013 Master Plan, there is an expectation that there could be significant post-2031 growth extending further into greenfield areas outside of the current urban boundary. In the development of the Water Servicing Strategy and recommendation of specific projects, the 2013 Master Plan considered the long-term greenfield growth scenario that could occur and ensured that flexibility is built into the program. However, similar to the servicing requirements to accommodate post-2031 intensification, the magnitude and location of growth will have a significant impact on the transmission and pumping upgrades, as well as plant upgrade requirements.
