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 map below presents data regarding compliance with the WSER effluent quality standards according to their averaging period. Wastewater systems must report on either a monthly, quarterly or annual basis. The dataset also includes the carbonaceous biochemical oxygen demand (CBOD) and suspended solids (SS) results for each wastewater system. Annual reporting: This map layer shows whether or not the wastewater systems met the WSER effluent quality limit according to an annual averaging period for carbonaceous biochemical oxygen demand CBOD or suspended solids SS. Quarterly reporting: This map layer shows whether or not the wastewater systems met the WSER effluent quality standards according to a quarterly averaging period. Note that a system that meets its CBOD limit or its SS limit for more than 75% of the time is considered to be in compliance with the effluent quality standards of the WSER.Monthly reporting: This map layer shows whether or not the wastewater systems met the WSER effluent quality standards according to a monthly averaging period. Note that a system that meets its CBOD limit or its SS limit for more than 75% of the time is considered to be in compliance with the effluent quality standards of the WSER.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.Data from Quebec and YukonThe data for Quebec municipalities (after 2017) is provided to the department separately through the equivalency agreement that was finalized in October 2018. Beginning in 2015, the data reported for the Yukon is provided to the department separately through an equivalency agreement finalized in 2014.More information on the wastewater sector including the regulations, agreements, contacts and resource documents is available at: https://www.canada.ca/wastewater

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. Under the WSER, owners or operators of wastewater systems discharging annual average daily effluent volumes greater than 2,500 m3 are required to determine and report on the acute lethality of the effluent.The map below presents the percentage of acute lethality test failures for the wastewater systems in Canada that conducted at least one acute lethality test according to the standards of the Wastewater Systems Effluent Regulations. 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 Excel or CSV formats.Data from Quebec and YukonAs of 2018, no acute lethality results from Quebec municipalities are available since an equivalency agreement is now in effect. As of 2015, no acute lethality test results for wastewater systems in the Yukon are available as an equivalency agreement in is effect.More information on the wastewater sector including the regulations, agreements, contacts and resource documents is available at: https://www.canada.ca/wastewater

The WSER set national baseline effluent quality standards that are achievable through secondary wastewater treatment. The WSER require owners or operators of wastewater systems with combined sewers to submit an annual report on the total volume and the number of days wastewater is discharged per month via combined sewer overflow (CSO) points as a result of precipitation.The map below shows the volume of effluent (in cubic metres) discharged in a year from all CSO points situated within the collection area of a wastewater system. For the most part, the volumes provided to ECCC are estimates.Please note, a value of “999999999” in the dataset indicates that the volume data is unavailable and it does not mean that a volume of 999,999,999 m3 was released within the collection area of a 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.Data from QuebecAs of 2018, no combined sewer overflow volumes from Quebec municipalities are available since an equivalency agreement is now in effect.More information on the wastewater sector including the regulations, agreements, contacts and resource documents is available at: https://www.canada.ca/wastewater

The Canadian Nuclear Safety Commission (CNSC) and Environment and Climate Change Canada (ECCC) are publishing databases with effluent and environmental monitoring results from nuclear facilities located along the Ottawa River watershed as part of the Regional Information and Monitoring Network (RIMNet) for the Ottawa River Watershed Basin initiative. The facilities included are Chalk River Laboratories, Nordion Canada Inc., SRB Technologies Canada Inc., and Nuclear Power Demonstration Waste Facility. The initiative was developed to address questions and concerns expressed by members of the public and Indigenous Nations and communities about the availability of publicly accessible environmental monitoring data in the Ottawa River Watershed Basin. More information about the initiative is available here: https://www.cnsc-ccsn.gc.ca/eng/resources/environmental-protection/rimnet/ This dataset contains effluent and environmental monitoring results from Chalk River Laboratories, Nordion Canada Inc., SRB Technologies Canada Inc., and Nuclear Power Demonstration Waste Facility. All of the effluent and emissions releases to the environment in this dataset are below the CNSC licensed release limits. All of the environmental monitoring results in this dataset are below environmental quality guidelines. More information about CNSC staff’s assessment of these facilities are found in CNSC staff’s regulatory oversight reports: https://www.cnsc-ccsn.gc.ca/eng/resources/publications/reports/regulatory-oversight-reports/
