SAVIGNE L EVEQUE Mortrie Wastewater Treatment Plant, Savigné-l'Évêque, France

SAVIGNE L EVEQUE Mortrie is a municipal wastewater treatment plant located in Savigné-l'Évêque, within the Sarthe department of Pays de la Loire, France. The facility serves a population of approximately 3,550 and has a designed capacity of 3,500 cubic meters per day, with a current discharge volume of 633.31 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and European standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size require secondary treatment, but the plant's advanced status indicates it likely discharges into a sensitive area or provides additional protection for the local environment. The treated effluent is discharged into local waterways that flow through the Sarthe River basin, ultimately reaching the Loire River and the Atlantic Ocean. The plant plays a key role in protecting the region's water quality, supporting aquatic life, and maintaining the ecological health of downstream environments.

The plant discharges into the Sarthe River basin, a tributary of the Loire River, which flows into the Bay of Biscay (Atlantic Ocean). The Loire is one of Europe's last wild rivers, supporting diverse aquatic species including migratory fish such as Atlantic salmon and European eel. The advanced treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and maintaining water quality for biodiversity.
