HONFLEUR Wastewater Treatment Plant, La Rivière-Saint-Sauveur, Normandy

The HONFLEUR wastewater treatment plant is located in La Rivière-Saint-Sauveur, Normandy, France, serving a population of approximately 13,286. The plant is situated in the industrial port zone and is part of the municipal wastewater infrastructure for the Honfleur area. As a French wastewater treatment facility, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating a medium-scale facility. The treated effluent is discharged into the Seine Bay, which is part of the English Channel ecosystem. This coastal discharge supports local marine biodiversity and is subject to stringent EU regulations to protect water quality in sensitive coastal areas.

The plant discharges into the Seine Bay, a coastal area of the English Channel that supports diverse marine life, including fish nurseries and migratory bird populations. The bay receives freshwater from the Seine River and other smaller coastal streams, creating a brackish estuarine environment. Protecting this watershed is critical for maintaining water quality in the Channel and supporting local fisheries and tourism.
