Carentoir Le Moulin Renaud is a wastewater treatment plant located in Carentoir, a commune in the Morbihan department of Bretagne, France. The plant serves a population of 2,244 and is part of the region's municipal wastewater infrastructure, operating under French regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 6,500 m³/day and an actual discharge volume of 400.33 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Vilaine River basin and then into the Atlantic Ocean. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the region, including the Vilaine estuary and the Gulf of Morbihan, which support diverse marine life and are important for local fisheries and tourism.
Environmental context
The plant discharges into the local watershed, which is part of the Vilaine River basin. The Vilaine flows into the Atlantic Ocean via the Morbihan Gulf, a semi-enclosed marine area known for its rich biodiversity and shellfish farming. The advanced treatment level helps minimize nutrient loading, protecting the gulf from eutrophication and supporting the ecological health of the downstream environment, which includes important habitats for migratory birds and marine species.
