CHANCEAUX SUR CHOISILLE La Bourdilliere Wastewater Treatment Plant, France

CHANCEAUX SUR CHOISILLE La Bourdilliere is a wastewater treatment plant located in Chanceaux-sur-Choisille, in the Centre-Val de Loire region of France. The plant serves a population of 2,717 and has a designed capacity of 3,600 cubic meters per day, with an average discharge volume of 484.71 cubic meters 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 is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies. 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 such as Atlantic salmon and European eel. The plant's advanced treatment helps minimize nutrient pollution and safeguard water quality in this ecologically significant river basin.

The plant discharges into the Choisille River, a tributary of the Loire River. The Loire flows westward through the Centre-Val de Loire region and into the Bay of Biscay (Atlantic Ocean). The Loire basin supports diverse aquatic life, including migratory fish, and is an important ecological corridor. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and aquatic habitats.
