SAINT REMY SUR AVRE Wastewater Treatment Plant, Saint-Germain-sur-Avre, Normandy

SAINT REMY SUR AVRE is a municipal wastewater treatment plant located in Saint-Germain-sur-Avre, a commune in the Eure department of Normandy, France. The plant serves a population of approximately 2,983 people, placing it in the small agglomeration category under French and EU regulations. It is situated inland, away from coastal areas, and treats wastewater from the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 m³/day and an average daily discharge of 532.16 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The plant is part of France's national wastewater infrastructure, regulated under the French Public Health Code and the Water Law, which transpose EU directives. The treated effluent from SAINT REMY SUR AVRE is discharged into the local watershed, which ultimately drains into the Seine River basin. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic life and providing water for agriculture, industry, and recreation. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Seine estuary.

The plant discharges into the local watercourse within the Seine River basin, which flows northward through the Île-de-France region and into the English Channel. The Seine estuary is an ecologically sensitive area that supports migratory fish species and serves as a critical habitat for birds. Advanced treatment at the plant reduces nutrient loads, helping to mitigate eutrophication risks in the downstream river and coastal zone.
