2023 Wet Weather Flow Master Plan Implementation Update

The Wet Weather Flow Master Plan also provides guidance on municipal operations, environmental monitoring and public education initiatives related to stormwater management. Significant progress has been made on critical Wet Weather Flow Master Plan initiatives, most notably, construction of the Don River and Central Waterfront Project which is the largest and most significant stormwater management program in the city's history, the Basement Flooding Protection Program, the rehabilitation of City stormwater management facilities, and in implementation of works within the watercourse and shoreline management programs. Policy updates to guide stormwater management for development and redevelopment have also been initiated. Challenges due to construction cost escalation, constrained engineering and technical resources and competing commitments have impacted the implementation of the Wet Weather Flow Master Plan, however key initiatives such as the construction of the Don River and Central Waterfront Project (and related projects - the Integrated Pumping Station and the High Rate Treatment Facility at the Ashbridges Bay Treatment Plant), critical end-of pipe projects and Basement Flooding Protection Program projects remain top priorities. Implementation of the Wet Weather Flow Master Plan is funded by investments set out in Toronto Water's annual capital budget and is primarily funded by the water rate with supplementary contributions from Development Charges, and federal funding through the Disaster Mitigation Adaptation Fund.
