Cherry Street Stormwater Treatment System

completed

The innovative stormwater management system integrates pieces across the waterfront with state-of-the-art technology and world-class architecture to prevent flooding and remove pollutants before water is released into the lake. Although largely hidden from view, managing and treating stormwater is critical to convey runoff, prevent flooding, and to ensure pollutants are removed from the water prior to being discharged into Lake Ontario. Planned in line with our Resilience and Innovation Framework for Sustainability, the Cherry Street stormwater management system addresses both day-to-day stormwater management, as well as extreme weather events, ensuring it will function in challenging conditions to alleviate pressure on our existing systems. While many stormwater treatment systems combine sewer systems with stormwater overflows, this system is purpose-built to treat stormwater using a combination of several adapted technologies as well as the main shaft as part of the treatment process. Serving East Bayfront, the West Don Lands (including the Canary District) and future communities in the Keating Channel Precinct, the integrated system protects these communities from flooding by safely capturing and conveying stormwater. It also removes pollutants before directing water to the lake, laying the groundwork for a cleaner waterfront and helping new neighbourhoods and communities thrive.
