Two Viable Alternatives The Individual Environmental Assessment project team completed a detailed assessment of the following two viable alternatives: Lake Simcoe Water 2. 1. Discharge to Lake Ontario Reclamation Centre and YDSS Improvements Lake Simcoe Water Reclamation Centre East Gwillimbury Newmarket 28 MLD 5 MLD East Gwillimbury Newmarket 5 MLD 3 MLD 28 MLD 3 MLD New Sewer System Aurora Aurora 11 MLD 11 MLD Modifications to existing YDSS Modifications to existing YDSS Slide 6

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 Proposed Lake Simcoe Water Reclamation Centre Proposed Pumping Station Proposed Treated Water Discharge Town of East Gwillimbury Outfall Proposed Sanitary Linear infrastructure Town of Newmarket Proposed Treated Water Discharge Linear Infrastructure Existing Newmarket Pumping Station Slide 8

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 11

Total Phosphorus (TP) Off-set Strategy  Approximately 168 kg/yr of new 168 phosphorus would be discharged to the Lake Simcoe watershed by the Water Reclamation Centre 336  Project specific phosphorus off-setting program would address this increase 168 through removal of other phosphorus sources at an approximate ratio of 2:1 Result would be a net reduction of approximately 168 kg/yr of total phosphorus in the Lake Simcoe watershed Slide 12

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 13

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 14

Reclaimed Water Infrastructure The reclaimed water infrastructure will include three major components: The WRC 1. Distribution system to reach the 2. customers  Sod Farms and Golf Courses  Forests  Industrial (future) Off-site facilities at customer site 3.  Pressurized service and storage Slide 15

16 16 Upper York Sewage Servicing Project Status  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 Slide 16
