NOUAILLE MAUPERTUIS Wastewater Treatment Plant - Nouaillé-Maupertuis, Nouvelle-Aquitaine, France

The NOUAILLE MAUPERTUIS wastewater treatment plant is located in Nouaillé-Maupertuis, a commune in the Vienne department of Nouvelle-Aquitaine, France. It serves a population of approximately 1,960 people, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 m³/day and an average discharge volume of 349.66 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 Clain River, a tributary of the Vienne River, and then into the Loire River before reaching the Atlantic Ocean. The plant plays a key role in protecting the water quality of these rivers and the downstream environment, supporting aquatic life and recreational uses.

The plant discharges into the local watershed that feeds the Clain River, a tributary of the Vienne River, which flows into the Loire River and eventually the Atlantic Ocean. This region supports diverse aquatic ecosystems, including fish populations and riparian habitats. The advanced treatment level helps minimize nutrient and pollutant loads, reducing the risk of eutrophication in downstream water bodies.
