Storm Water System

Storm water runoff includes rainwater and snowmelt that flows across the land and enters a network of storm water infrastructure in Saskatoon, including pipes, culverts, ditches, outfalls, manholes, and catch basins. 

Storm water is collected via storm drains, usually located at the curbs of roads, and then moved via a piping system to large mainline pipes. Eventually the storm water flows into the South Saskatchewan River. 

This storm water system is a vital part of the City's infrastructure. Managing storm water protects the health and safety of the public and the environment by mitigating flooding and erosion, and preventing pollutants from reaching our waterways.

If you cause a spill or discover one in the storm water system or in the South Saskatchewan River, please report it. 

Trash Trap Bag Pilot Project

In 2021, the City of Saskatoon in partnership with USask, received funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) to install trash trap bags at two storm water outfalls: near Prince of Wales Avenue and Spadina Crescent East, and near Pembina Avenue and Spadina Crescent East. 

The bags collect trash that ends up in the storm water system. When the bag fills, the trash is collected and analyzed, and the storm water is tested for potential pollutants. This is done to possibly help identify the source of any harmful contents or pollutants entering the South Saskatchewan River.

Results of the pilot project will determine whether the installation of trash trap bags at other outfalls throughout the City are an efficient way to prevent debris fron entering the river. It is a continuation of storm water quality research between the City and USask.
