Wastewater Systems Effluent Regulations Reported Data 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 regulations also specify requirements for carrying out effluent monitoring, reporting and record keeping. These files contain information about each wastewater system as reported in the Effluent Regulatory Reporting Information System (ERRIS) by the owners/operators of each wastewater system subject to the WSER for the years 2013 to 2018. The datasets include wastewater system information such as treatment types and discharge point locations, concentrations of carbonaceous biochemical oxygen demanding matter and suspended solids, acute lethality test results, and volumes of effluent discharged from the final discharge point and from combined sewer overflow points. Data not included The data for the 2018 reporting year does not include wastewater data from municipalities in the province of Quebec. This data is not reported in ERRIS and is provided to the department separately through the equivalency agreement that was finalized in October 2018. Supplemental Information Environment and Climate Change Canada (ECCC) developed the Effluent Regulatory Reporting Information System for the ownersof wastewater systems subject to the WSER to submit identification reports, on-going effluent monitoring reports, combinedsewer overflow reports as well as transitional and temporary authorization applications. The reports are submitted to ECCCto assess compliance with the national effluent quality standards for carbonaceous biochemical oxygen demanding matterand suspended solids. Certain regulatees are also required to submit the results of acute lethality testing.
