Timeline for solutions
As soon as the water capacity constraint was confirmed, the Region began fast-tracking projects to restore sustainable operations and resiliency in the Mannheim Service Area, as well as support growth. Based on the preliminary solutions and tentative timelines, we expect to have surplus water capacity in this service area (up to 600 L/s added) by 2032, and we are working to allow new development to proceed in stages between now and then.
Many of these solutions are in the Region’s 10-year capital plan. More projects under the Region’s Water Supply Strategy Update will identify water needs up to 2051 and how to meet them.
2026: Ongoing rehabilitation work (No net new water capacity)
- Parkway repairs – Completed
- Repairs to treatment equipment at Well K23 – Underway
- Rehabilitation of Well K93 – Underway
- Greenbrook repairs – Underway
2026–2027: Adding new water capacity (Up to 364 L/s)
- Modified operations at Greenbrook – Q4 2026
- Mannheim WTP Side Stream Stage 1 – Planning underway
- Mannheim WTP Side Stream Stage 2 – Summer 2027
Note: Mannheim Water Treatment Plant Side Stream Treatment is temporary until the long-term filtration upgrades at the plant are completed.
2029–2032: Adding new water capacity (Up to 277 L/s)
- Parkway well optimization (Well K32) – 2029
- New Maple Grove Water System – 2030
- Expand/Replace Greenbrook Water System – 2031
- Cam 2W Pump Station and associated watermains – 2031
- Mannheim WTP plate settler replacement – 2032
- New Grand River Water System (K70s and K80s wells) – 2032
Note: Any gain in supply from the Cam 2W Pump Station is not new water supply for the Integrated Urban System; it is a transfer from the Middleton Service Area to the Mannheim Service Area. The north-west area of Cambridge is within the Mannheim Service Area and has been identified as a strategic area for growth (referred to as the East Side Lands).
