ELBEUF SUR SEINE Wastewater Treatment Plant, Saint-Aubin-lès-Elbeuf, Normandie

The ELBEUF SUR SEINE wastewater treatment plant is located in Saint-Aubin-lès-Elbeuf, within the Normandie region of France. It serves a population of approximately 94,000 people, making it a medium-to-large agglomeration under EU classification. The plant is situated near the Seine River, which is a major waterway in northern France. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For sensitive areas, tertiary treatment may be mandated. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and European water quality requirements. The treated effluent is discharged into the Seine River, which flows through Rouen and eventually into the English Channel at Le Havre. The Seine basin supports diverse aquatic life and is an important ecological corridor. The plant plays a key role in protecting the river's water quality and downstream ecosystems.

The plant discharges into the Seine River, which flows northwest through Normandy to the English Channel. The Seine estuary is a critical habitat for migratory fish such as salmon and eels, and supports diverse bird populations. The plant's operations help maintain water quality in this ecologically sensitive river system, which is also used for drinking water abstraction and recreation downstream.
