Valençay Wastewater Treatment Plant, Centre-Val de Loire, France

The Valençay wastewater treatment plant is located in the commune of Valençay, in the Indre department of the Centre-Val de Loire region, France. It serves a population of 2,213 and is part of the municipal wastewater infrastructure for the area. The plant is situated inland, away from coastal zones, and treats wastewater from the local community. 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 4,000 m³/day and an actual discharge volume of 394.80 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The advanced treatment helps protect the water quality of the receiving water bodies and supports the ecological health of the downstream environment, including aquatic habitats and biodiversity.

The plant discharges into the local watershed within the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire basin supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps minimize nutrient and pollutant loads, protecting downstream water quality and the sensitive ecosystems of the Loire estuary.
