BOISSIERE DES LANDES Bourg Wastewater Treatment Plant, La Boissière-des-Landes, France

BOISSIERE DES LANDES Bourg is a municipal wastewater treatment plant located in the Zone Artisanale des Acacias in La Boissière-des-Landes, within the Vendée department of Pays de la Loire, France. The plant serves a population of approximately 1,967 and is part of the region's wastewater infrastructure for small agglomerations. 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. With a designed capacity of 550 m³/day and an average daily discharge of 350.91 m³/day, the facility operates below its maximum capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Atlantic Ocean via the Vendée coastal basin. The plant plays a role in protecting the region's rivers and coastal waters from nutrient pollution, supporting aquatic ecosystems and recreational uses downstream.

The plant discharges into the local watershed of the Vendée region, which flows into the Bay of Biscay in the Atlantic Ocean. This coastal area supports diverse marine life and is important for fisheries and tourism. The secondary treatment helps reduce organic pollutants and suspended solids, mitigating eutrophication risks in the downstream estuarine and coastal environments.
