SAINTE HERMINE Choreau Wastewater Treatment Plant, Saint-Jean-d'Hermine, France

SAINTE HERMINE Choreau is a wastewater treatment plant located in Saint-Jean-d'Hermine, in the Vendée department of Pays de la Loire, France. It serves a population of 1,483 and has a designed capacity of 2,250 m³/day, with a current discharge volume of 264.56 m³/day. The plant provides advanced treatment, which goes 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, helping to protect sensitive water bodies from eutrophication. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Lay River or nearby coastal waters. The region's rivers support diverse aquatic life and are important for local agriculture and tourism. The plant's advanced treatment helps minimize nutrient loading and protect downstream ecosystems.

The plant discharges into the local watershed in the Vendée region, which drains into the Lay River and eventually the Atlantic Ocean. This coastal area supports diverse aquatic life and is important for migratory fish species. Advanced treatment reduces nutrient pollution, helping to prevent eutrophication in downstream estuaries and coastal zones.
