Combined Sewer Overflow points - Wastewater Systems Effluent Regulations

The Wastewater Systems Effluent Regulations (WSER), developed under the Fisheries Act, came into force in 2012 to manage wastewater releases by systems that collect an average daily influent volume of 100 cubic metres or more. The WSER also does not apply to any wastewater system located in the Northwest Territories, Nunavut and north of the 54th parallel in the provinces of Quebec and Newfoundland and Labrador. The WSER set national baseline effluent quality standards that are achievable through secondary wastewater treatment.

The province of Quebec provided some combined sewer overflow data for 2020, which includes information on whether a discharge occurred at a combined sewer overflow point during the year. The map below shows the number of CSO points with at least one overflow event within each wastewater system.

The map is available in both ESRI REST (to use with ARC GIS) and WMS (open source) formats. For more information about the individual reporting wastewater systems, datasets are available in either CSV or XLS formats.

Supplemental Information

Environment and Climate Change Canada (ECCC) developed the Effluent Regulatory Reporting Information System for the owners of wastewater systems subject to the WSER to submit identification reports, on-going effluent monitoring reports, combined sewer overflow reports as well as transitional and temporary authorization applications. The reports are submitted to ECCC to assess compliance with the national effluent quality standards for carbonaceous biochemical oxygen demanding matter and suspended solids. Certain regulatees are also required to submit the results of acute lethality testing.
