TALMONT SAINT HILAIRE Beauregard Wastewater Treatment Plant, Talmont-Saint-Hilaire, France

The TALMONT SAINT HILAIRE Beauregard wastewater treatment plant is located in the Parc de la Salle Roy area of Talmont-Saint-Hilaire, a commune in the Vendée department of the Pays de la Loire region, western France. The plant serves a population of about 13,836 people, placing it in the medium agglomeration category under French and EU regulations. As a French wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), and it is situated near the Atlantic coast, within 50 km of the coastline. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Vendée coastal rivers. This coastal discharge requires careful management to protect marine water quality and the sensitive coastal ecosystems of the Bay of Biscay.

The plant discharges into the local watershed that flows to the Atlantic Ocean along the Vendée coast. This area supports diverse marine life and is part of the Bay of Biscay ecosystem, which is important for fisheries and migratory birds. The proximity to the coast means that nutrient and pollutant loads from wastewater must be controlled to prevent eutrophication and protect bathing water quality.
