Municipal Wastewater Effluent Strategy: Studies to Determine the Effluent Discharge Objectives for Wastewater Treatment Plants in Saskatchewan, Canada

Municipal wastewater usually contains many substances that may have risks for human health and environment protection. The Canadian Council of Ministers of Environment (CCME) has developed a Canada-wide Strategy for the Management of Municipal Wastewater Effluent (also called MWWE Strategy) for effluent discharged into surface water from wastewater treatment plants. The Strategy requires all municipal wastewater treatment plants in Canada including Saskatchewan that are discharging effluent into fish-bearing waters to achieve National Performance Standards (NPS) and develop site-specific Effluent Discharge Objectives (EDOs). The strategy also helps to better manage the wastewater facilities and to set up the standard for the future new facilities (CCME, 2009).
