ROCHES PREMARIE ANDILLE VANGUENAND Wastewater Treatment Plant, Roches-Prémarie-Andillé, France

ROCHES PREMARIE ANDILLE VANGUENAND is a wastewater treatment plant located in Roches-Prémarie-Andillé, a commune in the Vienne department of Nouvelle-Aquitaine, France. The plant serves a population of 3,490 and is designed to handle a capacity of 3,600 cubic meters per day, with an average discharge volume of 622.61 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 typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a French facility, it operates under national regulations transposing the directive, overseen by the local water agency (Agence de l'Eau Loire-Bretagne). The treated effluent is discharged into local water bodies within the Loire-Bretagne basin, ultimately draining into the Atlantic Ocean via the Loire River. The plant's advanced treatment helps safeguard the ecological health of downstream rivers and wetlands, supporting biodiversity and water quality in the region.

The plant discharges into the local watershed within the Loire-Bretagne basin, which flows into the Atlantic Ocean via the Loire River. The region supports diverse aquatic life and is part of a network of rivers and wetlands that provide important habitat for migratory fish and waterfowl. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
