Le Tour du Parc Wastewater Treatment Plant, Brittany, France

Le Tour du Parc wastewater treatment plant is located in the commune of Le Tour-du-Parc in the Brittany region of northwestern France. The plant serves a population of 1,204 and is situated along the coastal path near Balanfournis, within the Morbihan department. As a small agglomeration, it plays a key role in managing local wastewater in this scenic coastal area. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into coastal waters. The plant has a designed capacity of 4,400 cubic meters per day, with an average daily discharge volume of approximately 215 cubic meters, indicating ample reserve capacity for future growth or seasonal variations. The treated effluent is discharged into the coastal waters of the Bay of Biscay, a sensitive marine environment that supports diverse aquatic life and important fisheries. The plant's operation helps protect the local coastline and the Gulf of Morbihan, a semi-enclosed sea known for its rich biodiversity and tourism value.

The plant discharges treated wastewater into the coastal waters of the Bay of Biscay, which ultimately connects to the Atlantic Ocean. The local watershed includes the Ria d'Etel and the Gulf of Morbihan, both ecologically sensitive areas that support diverse marine life, including migratory fish and seabirds. The region's coastal habitats are important for tourism and fishing, making effective wastewater treatment critical to maintaining water quality.
