Parigné-l'Évêque Wastewater Treatment Plant - Advanced Treatment in Pays de la Loire

The Parigné-l'Évêque wastewater treatment plant, located on Chemin de Corlevé in the Sarthe department of Pays de la Loire, serves a population of 2,646. This facility is part of France's municipal wastewater infrastructure, operating under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a designed capacity of 3,500 m³/day and a current discharge volume of 472 m³/day, the facility has ample reserve capacity to accommodate future growth. The treated effluent is discharged into local watercourses that ultimately drain into the Sarthe River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for fish species. The plant's advanced treatment helps protect water quality in this sensitive watershed.

The plant discharges into the Sarthe River basin, which flows into the Loire River and eventually the Atlantic Ocean. The Loire watershed is ecologically sensitive, supporting diverse aquatic habitats and migratory fish populations. Advanced treatment at this plant helps reduce nutrient loading and protect downstream water quality.
