Municipal wastewater treatment

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Municipal wastewater treatment indicator The municipal wastewater treatment indicators measure the level of wastewater treatment provided to the Canadian population and track the compliance of the treated water discharged with the national effluent quality standards. Higher treatment levels of wastewater reduce the risk of raw wastewater pollutants entering the environment, where they pose risks to human health and the environment. This indicator is not a measure of municipalities' compliance with municipal, provincial or federal wastewater regulations or treatment standards. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
