NAVEIL prepatour Wastewater Treatment Plant, Naveil, Centre-Val de Loire

NAVEIL prepatour is a wastewater treatment facility located in the commune of Naveil, within the Centre-Val de Loire region of France. The plant serves a population of approximately 2,392 residents, classifying it as a small agglomeration under French and EU regulations. Its address is Rue de la Vallée, Prépatour, Naveil, Vendôme, Loir-et-Cher. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 7,400 cubic meters per day, and the reported discharge volume is 426.73 cubic meters per day, indicating operational headroom. Treated effluent from Naveil prepatour is discharged into the local water system, which ultimately drains into the Loire River, one of France's major rivers. The Loire basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species such as Atlantic salmon and European eel. The plant's advanced treatment helps reduce nutrient loading and protect downstream water quality in this ecologically significant river system.

The plant discharges into the local watershed that feeds the Loire River, which flows into the Bay of Biscay (Atlantic Ocean). The Loire basin is ecologically sensitive, supporting diverse aquatic life and serving as a critical migratory route for fish. Advanced treatment at this plant helps minimize nutrient pollution, safeguarding the river's water quality and downstream habitats.
