Municipal wastewater treatment

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 measures the level of wastewater treatment provided to the Canadian population. Higher levels of wastewater treatment reduce the risk of pollutants from raw wastewater reaching the environment, where they pose risks to human and environmental health. 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.
