Condé-sur-Vire Wastewater Treatment Plant, Le Mesnil-Raoult, Normandy

The Condé-sur-Vire wastewater treatment plant is located in Le Mesnil-Raoult, a commune in the Manche department of Normandy, France. It serves a population of approximately 5,000 people and is part of the municipal wastewater infrastructure for the Condé-sur-Vire area. The plant is situated inland, more than 10 km from the coast, but within 50 km of the English Channel. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 40,000 m³/day, the plant has significant headroom for future growth, as current discharge volume is only 891.99 m³/day. The facility operates under French national regulations that implement the EU directive, ensuring high-quality effluent standards. The treated wastewater is discharged into the local watershed, which ultimately drains into the English Channel via the Vire River and its estuary. The Vire River supports diverse aquatic life and is an important ecological corridor in the Normandy region. The plant's advanced treatment helps protect downstream water quality and the sensitive coastal environment of the Baie des Veys and the English Channel.

The plant discharges into the Vire River basin, which flows into the Baie des Veys and then the English Channel. The Vire River supports diverse aquatic ecosystems, including fish populations and riparian habitats. The downstream estuary is a significant ecological area for migratory birds and marine life. Advanced treatment at the plant helps minimize nutrient and pollutant loads, protecting the sensitive coastal waters of the English Channel.
