Overview
TALMONT SAINT HILAIRE Les Girondines is an advanced wastewater treatment plant in Talmont-Saint-Hilaire, Pays de la Loire, France. It serves about 4,055 people with a design capacity of 10,000 m³/day and discharges treated water near the Atlantic coa
TALMONT SAINT HILAIRE Les Girondines is a wastewater treatment facility located in Talmont-Saint-Hilaire, a commune in the Vendée department of Pays de la Loire, France. The plant serves a population of approximately 4,055 residents and has a designed capacity of 10,000 cubic meters per day, indicating it is sized to accommodate seasonal population fluctuations common in coastal tourist areas. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant discharges a daily volume of about 723 m³, well below its capacity, suggesting efficient operation or low inflow. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The plant's proximity to the coast (within 10 km) makes its advanced treatment level particularly important for protecting coastal water quality and marine ecosystems. The facility contributes to the environmental health of the Baie de Bourgneuf and the broader Bay of Biscay.
Environmental context
The plant discharges into the coastal watershed of the Vendée region, with treated effluent flowing via small coastal rivers into the Atlantic Ocean. The receiving waters include the Baie de Bourgneuf, an ecologically sensitive area that supports diverse marine life, including shellfish beds and migratory bird populations. The advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in these productive coastal waters.
