MULSANNE route de Teloche Wastewater Treatment Plant, Mulsanne, Pays de la Loire

MULSANNE route de Teloche is a wastewater treatment plant located in Mulsanne, a commune in the Sarthe department of Pays de la Loire, France. The plant serves a population of approximately 4,200 people and has a designed capacity of 6,200 cubic meters per day, with an average discharge volume of 749.27 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters, aligning with France's implementation of the directive in sensitive areas. The treated effluent is discharged into the local watershed, which ultimately drains 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 species such as Atlantic salmon. The plant's advanced treatment helps reduce nutrient loading and protect downstream water quality.

The plant discharges into the local watershed that flows into the Sarthe River, a tributary of the Loire River. The Loire basin is one of France's largest river systems, supporting diverse aquatic ecosystems and providing critical habitat for migratory fish species. Advanced treatment at this plant helps minimize nutrient pollution, protecting the ecological health of the Sarthe and Loire rivers.
