FLEURY SUR ANDELLE Wastewater Treatment Plant, Radepont, Normandy

FLEURY SUR ANDELLE is an advanced wastewater treatment plant located in Radepont, within the Eure department of Normandy, France. The facility serves a population of approximately 5,190 people, reflecting its role in managing municipal wastewater for this small agglomeration. The plant's designed capacity is 5,000 cubic meters per day, with a reported discharge volume of 925.89 cubic meters per day, indicating operational headroom. As an advanced treatment facility, it goes beyond secondary biological treatment to remove nutrients such as nitrogen and phosphorus, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. In France, such plants are regulated under national water law (Code de l'environnement) and typically require permits from local water agencies (Agences de l'eau). The advanced treatment level ensures compliance with stringent effluent standards for discharge into sensitive water bodies. The plant discharges treated wastewater into the local watershed, which is part of the Seine River basin. The Seine flows through Normandy and into the English Channel, supporting diverse aquatic ecosystems and providing water for agriculture and industry. By employing advanced treatment, the plant helps protect downstream water quality and the ecological health of the Seine estuary and coastal waters.

The plant discharges into the Seine River basin, which drains into the English Channel via the Seine estuary. This estuary is an ecologically sensitive area that supports migratory fish species and diverse bird populations. Advanced nutrient removal at the plant helps reduce eutrophication risks in the downstream marine environment, contributing to the overall health of the Normandy coastal ecosystem.
