The City of Winnipeg Water and Waste Department has identified that changes to the existing combined sewer system are required to alleviate basement flooding and reduce the number of combined sewer overflows in the Cockburn West-Calrossie sewer district of the River Heights/Fort Garry neighborhood. The proposed Parker Storm Retention Basin (SRB) is one component within the overall Cockburn and Calrossie Combined Sewer Relief Works Project.
The SRB will be built as a wetland with numerous environmental and community benefits. Naturalized SRBs contribute to better water quality of surrounding waterways by filtering out pollutants in stormwater. Landscaping will include native grasses and perennials that can remove significant amounts of carbon from the air while supporting butterflies, dragonflies, songbirds and other wildlife species.
