Upper York Sewage Solutions Recommended Ultimate Servicing Strategy

The Upper York Sewage Solutions recommended ultimate servicing strategy will convey wastewater from the service area to a Water Reclamation Centre and discharge treated water to the East Holland River

Slide 11

Lake Simcoe Watershed Key Considerations

 Water Reclamation Centre must align with:

 Lake Simcoe Protection Plan (LSPP)  Phosphorus Reduction Strategy (PRS)

 Elements of Environmental Assessment

approval include project specific:

 Total phosphorus off-set strategy  Reclaimed water use guidelines

Slide 12

 Approximately 168 kg/yr of new

phosphorus would be discharged to the Lake Simcoe watershed by the Water Reclamation Centre

 Project specific phosphorus off-setting

program would address this increase through removal of other phosphorus sources at an approximate ratio of 2:1

Result would be a net reduction of approximately 168 kg/yr

• f total phosphorus in the Lake Simcoe watershed

168 168 336

Total Phosphorus (TP) Off-set Strategy

Slide 13

Total Phosphorous Off-Setting Program

 Retrofitting 7 existing stormwater

management ponds

 Aurora – 1 pond  East Gwillimbury – 2 ponds  Newmarket – 4 ponds  Developing a new stormwater

management pond in Georgina

 Installing low impact development

technologies within an existing stormwater catchment area in Newmarket

The proposed off-sets will improve the water quality and quantity of the downstream watercourses that ultimately flow into Lake Simcoe

Slide 14

Reclaimed Water Use

 Reclaimed water is recognized in the Region

to help conserve regional water resources which are stressed in the summer

 Nutrients in reclaimed water will provide for

plant uptake through land irrigation, reducing need for chemical fertilizers

 Prime beneficiaries for the use of reclaimed

water:

 Sod farms  Tree farms  Golf courses  Industry (Future)

Slide 15

Reclaimed Water Infrastructure

The reclaimed water infrastructure will include three major components:

1.

The WRC

2.

Distribution system to reach the customers

 Sod Farms and Golf Courses  Forests  Industrial (future)

3.

Off-site facilities at customer site

 Pressurized service and storage

Slide 16

 Environmental Assessment Report

submitted to Ministry of Environment and Climate Change (MOECC) for approval – July 25, 2014

 MOECC approval – Anticipated for Q4 2015  Detailed design underway on all three key

design elements

 Geotechnical field investigations complete

for WRC site and outfall conveyance route

 Property acquisition process commenced  Landscape and building architectural design

concepts in development
