Completed in 2018 Environmental assessment

Lisgar Basement Water Infiltration Investigation

The City completed a number of actions in the Lisgar District to address the potential for basement water infiltration.

The City of Mississauga has completed a Municipal Class Environmental Assessment (EA) to determine the first preferred location and form of pumping station within the Lisgar District to reduce the potential for basement water infiltration.

The outcome of the Class EA Study determined the Preferred Solution to be a permanent foundation drain collector (FDC) Pumping Station and Utility Trench Dewatering Pumping System located on Black Walnut Trail at Cactus Gate Parkette. The Cactus Gate Parkette pumping station has been operational since spring 2021

The City is currently undertaking an additional Municipal Class EA study to determine the number, preferred location(s) and type(s) of future pumping Stations within the Lisgar District. Please visit the EA Study webpage for additional information.
