SAINT PIERRE EGLISE Wastewater Treatment Plant, Vicq-sur-Mer, Normandy

The SAINT PIERRE EGLISE wastewater treatment plant is located in Vicq-sur-Mer, a commune in the Manche department of Normandy, France. It serves a population of approximately 1,850 people, placing it in the small agglomeration category under French and EU regulations. The plant is situated near the coast of the English Channel, within 10 km of the shoreline. 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. It has a designed capacity of 2,300 m³/day and currently treats an average daily flow of 330 m³/day, indicating significant spare capacity. The facility operates under the French regulatory framework, which implements the EU directive through national legislation, ensuring compliance with discharge standards for sensitive coastal areas. The treated effluent is discharged into the local watershed, which drains into the English Channel. This coastal environment supports diverse marine life and is part of the larger Normandy coastal ecosystem. The advanced treatment level helps protect the receiving waters from nutrient pollution, safeguarding both local biodiversity and the broader marine environment of the Channel.

The plant discharges into the coastal watershed of the English Channel, a dynamic marine environment that supports diverse aquatic life including fish, crustaceans, and seabirds. The advanced treatment reduces nutrient loads, helping to prevent eutrophication in the nearshore zone. The area is ecologically sensitive due to its proximity to the coast and the presence of migratory species that rely on clean water.
