SAINT OUEN DE THOUBERVILLE Wastewater Treatment Plant, Saint-Ouen-de-Thouberville, Normandie

The SAINT OUEN DE THOUBERVILLE wastewater treatment plant is located in Saint-Ouen-de-Thouberville, a commune in the Eure department of Normandie, France. The plant serves a population of approximately 1,970 and has a designed capacity of 2,700 m³/day, with an average discharge volume of 351.44 m³/day. As a French wastewater facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The plant's advanced treatment level ensures high-quality effluent, meeting stringent standards for nutrient removal and pollutant reduction. The treated effluent is discharged into the local watershed, which ultimately drains into the Seine River basin and then into the English Channel. The plant plays a crucial role in protecting the Seine estuary and coastal marine environment from nutrient pollution and other contaminants.

The plant discharges into the Seine River basin, which flows through Normandie and into the English Channel. The Seine estuary is an ecologically sensitive area that supports diverse aquatic life, including migratory fish species. Advanced treatment at this plant helps reduce nutrient loads that could otherwise contribute to eutrophication in the coastal zone.
