The Don River and Central Waterfront Wet Wester Flow System & connected Projects is a 25-year program aimed at improving water quality in Toronto’s Lower Don River, Taylor-Massey Creek, and the Inner Harbour.
In August, Toronto City Council endorsed a plan to reach out to both the provincial and federal governments for funding assistance for the project, funding that would allow for the project to be completed up to eight years ahead of its current schedule.
The Coxwell Bypass Tunnel, as well as the integrated pumping station at the Ashbridges Bay Weastewater Treatment Plant, and new outfall at the plant, are among the first work to be undertaken as part of the overall program. Construction of the tunnel is underway now, and is scheduled for completion in 2023. The station project is anticipated to be completed by 2026, and the new outfall by 2025.
