Water and Wastewater Master Plan for the Lake-Based Systems 2
Why are we here?
As our communities grow, additional water and wastewater infrastructure will be required to meet the servicing needs
Therefore, the Region of Peel is updating the 2007 Water and Wastewater Master Plan
This study focuses on the Region’s lake-based systems to support growth to 2031 and to consider longer term servicing needs beyond 2031, as identified by Amendment 2 (2013) of the Places to Grow Growth Plan for the Greater Golden Horseshoe, 2006
This Public Information Centre (PIC) describes the master planning process and presents the preferred water and wastewater servicing strategies for 2031 as well as servicing considerations for post-2031 growth

• The Region developed projections based on Places to Grow as part of a growth conformity exercise, used for the Regional Official Plan Amendment (ROPA 24) and adopted by Council, providing a 2031 population of approximately 1.64 million. Forecasts at a Small Geographic Unit (SGU) level are based on data received from each municipality for ROPA 24 background studies. For the purposes of this Master Plan, the SGU data (Scenario B) was used for the baseline scenario and has been slightly revised throughout the process.
• Municipal input forecasts are described in ROPA 24 discussion paper “Places to Prosper – Managing Growth in Peel Region”
• Master Plan forecasts reflect the Census undercount.
Places to Grow is the Government of Ontario’s framework for implementing growth in the Greater Golden Horseshoe Region to 2031 and eventually to 2041. The Plan outlines the Region of Peel’s population and employment growth forecasts to 2031. Amendment 2 (2013) of the Plan will extend the forecasts to 2041.

York Region water requirements are defined in Schedule C of the York-Peel water servicing agreement. They are a key input to the long-term water servicing strategies of the Region of Peel.
The Master Plan is planning for York Region’s 2031 water requirement as per Schedule C in the York-Peel agreement at a rate of 388 million litres per day (ML/d)
The Master Plan is planning for York Region’s 2031 wastewater flows as per the York-Peel agreement at a rate of 53.2 million litres per day (ML/d)
The Region of Peel sends a small quantity of wastewater flows to the City of Toronto and receives a slightly larger quantity in return

Servicing concepts to address existing and
future servicing issues are first considered at
a high level, weighing the advantages and
disadvantages of each concept.
Concepts are refined to form detailed
strategies. Each strategy is subject to a five-
point evaluation, including environmental,
technical, socio/cultural, financial, and
legal/jurisdictional impacts.
The preferred strategy is then dissected into component parts, such as sewers and force mains,
pumping stations, storage facilities etc. Individual alignments and alternative facility sites are
identified and, where appropriate under the Class EA process, subjected to a siting and alignment
evaluation process.

Water ServicingLake Ontario based water supply for the City of Mississauga, the City of Brampton, and parts of the Town of CaledonGroundwater-based systems in the Town of Caledon are not covered under the Lake-Based Water and Wastewater Master PlanExisting Pressure Zones 1 through 7 service the study areaThe trunk water system comprises:
• Two water treatment plants (WTP): Lakeview WTP in the central system and Lorne Park WTP in the west system
• Trunk transmission mains (east-central-west or E-C-W)
• Pumping stations and storage facilities The lake-based water system currently
supplies a population of over 1.3 million In 2012, the Lakeview WTP and Lorne Park
WTP produced over 225 billion litres of water A portion of this water is supplied to York
Region
Existing Water SystemConstraints and Opportunities
Constraints and Opportunities
Optimize east-west transfers with distribution and pumping for improved service level and security
Reservoirs and pumping stations may require expansion for additional capacity
Additional storage capacity may be required to service the upper zones
Intensification areas (e.g., Mississauga City Centre, Hurontario Corridor, Downtown Brampton) may require
additional infrastructure capacity
There is a potential for additional post-2031 growth. The Master Plan will determine the potential impact of this
growth on infrastructure.

General Water Strategy
Current program at the Lakeview and Lorne Park Water Treatment Plants
Feedermain upgrades currently planned (i.e.,
Hanlan) are required and will meet P2G (2031) needs
The East Trunk System will supply a larger portion of the lower pressure zones and will be the primary source for the Hurontario Corridor and MCC
intensification areas
The currently planned facilities will meet the P2G
(2031) needs – no new storage or pumping facilities
required
Distribution system upgrades are required to support water
supply and distribution throughout the network
Water and Wastewater Master Plan for the Lake-Based Systems 15
Existing Wastewater SystemConstraints and Opportunities
Constraints and Opportunities
Provide operational flexibility for diverting flow from east to west system
Sewage pumping stations may require expansion for additional capacity
Intensification areas (e.g., Mississauga City Centre, Hurontario Corridor,
Downtown Brampton) may require additional infrastructure capacity
There is potential for additional growth to occur post-2031. The Master Plan will determine the potential impact of this
growth on infrastructure.

Most Preferred
Water and Wastewater Master Plan for the Lake-Based Systems 19
Preliminary Preferred Strategy – Wastewater
7
• 2031 Program remains consistent with the 2007 Master Plan strategy
• Recent expansion of the Clarkson Wastewater Treatment Facility is sufficient to service growth to 2031
• East-to-west diversion is required to support the overall strategy and maintain projected flows to the Wastewater Treatment Facility within 90% of the rated capacity
• By reducing inflow and infiltration, the Region expects that the system will experience lower wet weather response and will inherently increase peak wet weather flow capacity
• Continued intensification pressure, particularly in Mississauga
General Wastewater Strategy Sewer Upgrade Requirements:
• Twin pipes downstream of diversion (Old Derry Road)
• Convert gravity sewer to a force main as part of the east-to-west diversion
• Twin East Brampton Trunk Sewer• Extension of collection system in
northwest Brampton to service new growth areas
• East to West diversion gravity trunk sewer
Pumping Station Requirements:• Expand the McVean SPS to a firm
capacity of 2100 L/s• East-to-west sewage pumping station
Brampton Upgrade Requirements
Wastewater Treatment Facility Upgrade Requirements:
• Expand G.E. Booth Wastewater Treatment Facility from 486 ML/d to 518 ML/d
Sewer Upgrade Requirements:• Twin the west sanitary trunk sewer north
of the Clarkson Wastewater Treatment Facility
• Connection to a new west sanitary trunk sewer
• Upgrade trunk sewers to service Intensification Areas
Mississauga Upgrade Requirements
Sewer Upgrade Requirements:• Area to be serviced by Albion-Vaughan
sewer• Extension of collection system in Bolton• Extension of collection system for
servicing Mayfield West community phase II
Caledon Upgrade Requirements
Recent expansion of Clarkson Wastewater
Treatment Facility to 350 ML/d is sufficient to 2031
GE Booth Wastewater Treatment Facility will need to be expanded from 486 to 518 ML/d – this is already planned
and budgeted for
East to west diversion is required to defer Booth
expansion and maintain all plants within 90% of rated
capacity
Collection system upgrades are required to support
conveyance to the plants
Long term inflow/infiltration program is required to meet
continued level of service and defer/eliminate additional infrastructure upgrades
Water and Wastewater Master Plan for the Lake-Based Systems 20
Schedule B Project No. 1 – Wastewater
McVean ForcemainQueen Street E. between McVean Dr. and Goreway Dr.
Project will replace the existing 500 mm forcemain with a 900 mm forcemain, as additional forcemain capacity is required to be able to convey the upgraded firm capacity of the station.
Alternative routing alignment options are not applicable, as the project is based on a replacement to upgrade the existing forcemain.
Majority of the land to the west of McVean SPS is associated with the West Humber River Valley and TRCA Claireville Conservation Area.
No temporary easements are required for tie-ins to the SPS or Trunk Sewer at Goreway. For forcemainreplacement, temporary easements are required from TRCA.
Proposed forcemain can be constructed with manageable impacts to the socioeconomic, cultural and natural environment based on use of trenchless technologies and typical best construction practices and mitigation methods.
Forcemain will run east-west within the existing 6m easement and then the Queen St. ROW

Schedule B Project No. 2 – Wastewater
Lakeshore/Southdown Road Sanitary Trunk Sewer TwinningTrunk Sewer from Lakeshore Road to Clarkson Wastewater
Treatment Facility
Peak flow exceeding pipe capacity immediately upstream of the Clarkson Wastewater Treatment Facility triggers the need to this 1500 mm sewer to service future growth.
Trunk sewer routing options were identified and evaluated. Alternatives are based on transportation corridors, land use and possible connection to existing trunk sewer and the treatment facility.
Predominant land uses are industrial and open space, including some commercial and residential lands. Crossings include CVC regulation limit and Sheridan Creek.
Constructability and construction impacts will be evaluated. A cost/benefit analysis is currently being considered to help with the selection process.
Proposed trunk sewer can be constructed with manageable impacts to the socioeconomic, cultural and natural environment based on use of trenchless technologies and typical best construction practices and mitigation methods.
Very high impact due to lane reductions and possible closure of Inverhouse Drive.
Alternative C:PreliminaryPreferred Alignment
Alternative D:Considered as part of a potential Orr Rd. extension
Connection to proposed sewer to alleviate surcharging on existing Avonhead Sewer.

Schedule A+ Project No. 3 – Wastewater
Northwest Brampton Sanitary Trunk SewerHeritage Road from Wanless Drive to Bovaird Drive
Project is located in North West Brampton and is bounded by Wanless Drive to the north, Mississauga Road to the east, Bovaird Drive West to the south and Winston Churchill Boulevard to the west
Alternative routing alignment options were evaluated and preferred alignment will follow Heritage Rd. and future Sandalwood extension to Mississauga Rd.
Proposed trunk sewer avoids crossing CNR Railway and Credit River tributary. Construction will occur in the existing and/or future right away.
Project will be approved as a Schedule A+. Does not require further approval under Master Plan. (This has been updated since the notice of PIC)

Post 2031 Servicing Vision and Impact • The 2013 Master Plan provides perspective on the servicing impacts of post-2031 growth• Intensification and hypothetical sensitivity scenarios including additional intensification and/or growth in the
Caledon Agricultural and Rural Area were evaluated at a high level
As growth extends north, key servicing
issues include:
Growth may need to be located in new water
pressure zones – new pumping and storage
facilities would be required
Northern limits of the existing systems may
not have sufficient capacity to support
connections
Regardless of location, a minimum level of trunk
capacity upgrades including treatment
capacity expansion will be required
• Depending on the location of the intensification (even varying between corners of an intersection), the impact on the local distribution can vary greatly
• As the intensification hits a threshold additional plant capacity and intake will be triggered
Water
• Post P2G (2031) will trigger additional treatment capacity and trunk sewer / diversion needs
• Most intensification area flows to the GE Booth Wastewater Treatment Facility
Wastewater
It is difficult to provide the details of the impacts on existing infrastructure at this time, but impacts are being considered and analyses are underway
