AIRVAULT LE PRE NEUF Wastewater Treatment Plant, Airvault, Nouvelle-Aquitaine

AIRVAULT LE PRE NEUF is a wastewater treatment plant located in Airvault, in the Nouvelle-Aquitaine region of France. The plant serves a population of approximately 2,322 people, making it a small-scale facility within the local municipal infrastructure. It is situated in the Deux-Sèvres department, an inland area away from the coast. 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 4,600 m³/day and a discharge volume of 414.24 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As a French plant, it operates under national regulations that transpose EU directives, ensuring high environmental standards. The treated effluent from AIRVAULT LE PRE NEUF is discharged into a local watercourse, which eventually flows into the Thouet River, a tributary of the Loire. The Loire River is one of France's major rivers, draining into the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Thouet and Loire basins, supporting aquatic life and downstream ecosystems.

The plant discharges into a local stream that feeds into the Thouet River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic species and serving as a migratory corridor for fish such as Atlantic salmon and European eel. The advanced treatment at this plant helps minimize nutrient and pollutant loads, protecting the sensitive freshwater and estuarine environments downstream.
