The facility serves a population of around 39,695, classifying it as a medium-sized agglomeration under French and EU regulations. Its location near the Atlantic coast places it in a sensitive environmental zone. As a French wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. For plants in coastal areas, the directive may also mandate additional treatment to protect sensitive marine environments. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar units), indicating its scale of operation. The plant's treated effluent is discharged into the local watershed, which drains into the Atlantic Ocean. The coastal waters of the Vendée region support diverse marine life, including fish, shellfish, and seabirds. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of the nearby marine environment, which is also important for tourism and local fisheries.
Environmental context
The plant discharges into the local coastal watershed of the Vendée region, which flows into the Bay of Biscay in the Atlantic Ocean. This coastal area supports diverse aquatic life, including fish, shellfish, and migratory birds. The proximity to the coast means that treated effluent must meet stringent standards to avoid eutrophication and protect marine biodiversity.
