MAYET Le Moulin de la Roche is a wastewater treatment plant located in Mayet, a commune in the Sarthe department of the Pays de la Loire region, France. The plant serves a population of about 2,170 and has a designed capacity of 3,000 cubic meters per day, with a current discharge volume of 387.12 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. For plants serving fewer than 10,000 people, the directive mandates secondary treatment, but advanced treatment may be required in sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Loire River basin. The Pays de la Loire region features a mix of agricultural and natural landscapes, and the plant plays a role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into local streams that are part of the Loire River basin, one of France's major river systems. The Loire flows into the Atlantic Ocean, supporting diverse aquatic life and important migratory fish species. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream waters and maintaining ecological balance in the region.
