SAINT VALERY EN CAUX, Saint-Valery-en-Caux

Overview

SAINT VALERY EN CAUX wastewater treatment plant serves Saint-Valery-en-Caux in Normandy, France. It treats wastewater from approximately 6,400 residents and discharges into the local environment.

The SAINT VALERY EN CAUX wastewater treatment plant is located in Saint-Valery-en-Caux, a coastal commune in the Seine-Maritime department of Normandy, France. The plant serves a population of approximately 6,400 people, typical of a small agglomeration in the region. As part of France's wastewater infrastructure, it plays a key role in protecting local water quality. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have appropriate treatment systems. For coastal areas like Saint-Valery-en-Caux, which is within 50 km of the English Channel, the directive mandates at least secondary treatment to prevent nutrient pollution and protect marine environments. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized for the local population. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel. This coastal discharge requires careful management to minimize impacts on marine ecosystems, including bathing waters and fisheries. The plant contributes to the overall health of the Seine-Maritime coastline and supports compliance with the EU Bathing Water Directive.

Environmental context

The plant discharges into the local river system that flows into the English Channel near Saint-Valery-en-Caux. The coastal waters of this region support diverse marine life, including fish and shellfish, and are important for tourism and recreation. Nutrient loading from wastewater can lead to eutrophication, so effective treatment is essential to maintain water quality and protect the sensitive coastal ecosystem.
