VIRE Wastewater Treatment Plant, Vire Normandie, Normandy, France

The VIRE wastewater treatment plant is located in Vire Normandie, a commune in the Calvados department of Normandy, France. The plant serves a population equivalent of 22,427, classifying it as a medium-sized agglomeration under EU regulations. It is situated inland, away from the coast, and discharges into the local watershed. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires tertiary treatment if the receiving waters are designated as sensitive areas. Compliance with the directive ensures appropriate treatment standards. The plant's treated effluent is discharged into the Vire River, which flows through the Normandy region and eventually into the English Channel. The river supports diverse aquatic life and is an important ecological corridor. The plant plays a key role in protecting water quality in the Vire basin and downstream coastal environments.

The VIRE plant discharges into the Vire River, a coastal river in Normandy that flows into the Baie des Veys and then the English Channel.
