Overview
Pont-l'Évêque wastewater treatment plant serves Coudray-Rabut, France, treating wastewater for approximately 6,500 residents. The facility operates under France's implementation of the EU Urban Waste Water Treatment Directive.
The Pont-l'Évêque wastewater treatment plant is located in Coudray-Rabut, a commune in the Calvados department of Normandy, France. It serves a population of approximately 6,500 people, placing it in the small-to-medium agglomeration category under French regulations. The plant is situated near the historic town of Pont-l'Évêque, known for its cheese and proximity to the Normandy coast. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment (biological treatment) as a minimum standard. France has transposed this directive into national law, and the plant is expected to comply with these standards. The designed capacity is reported as 1.00 (likely in thousands of cubic meters per day), indicating a modest facility suited to the local population. The plant discharges treated effluent into the local watershed, which ultimately drains into the English Channel. The region's rivers, such as the Touques, support diverse aquatic life and are important for local ecosystems. The proximity to the coast (within 50 km) means that nutrient removal may be a consideration to protect coastal waters from eutrophication.
Environmental context
The plant's treated effluent flows into the Touques River basin, which drains into the Baie de Seine and the English Channel. This coastal zone supports diverse marine life and is an important area for migratory fish species. The Normandy coast is ecologically sensitive, with habitats that depend on good water quality. Nutrient loading from wastewater can impact these ecosystems, making treatment standards critical for environmental protection.
Frequently asked questions
