CHAMBRAY LES TOURS La Madeleine is a municipal wastewater treatment plant located in Chambray-lès-Tours, in the Centre-Val de Loire region of France. The plant serves a population of approximately 5,017 and has a designed capacity of 8,000 m³ per day, with an average discharge volume of 895 m³ per day. 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. This level of treatment typically includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The advanced treatment helps maintain water quality in this ecologically significant river system.
Environmental context
The plant discharges into the Loire River basin, which flows through the Centre-Val de Loire region and eventually reaches the Atlantic Ocean. The Loire River is known for its rich biodiversity, including migratory fish such as salmon and eels. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream aquatic habitats and supporting the ecological health of the river.
