CIVRAY nouvelle Wastewater Treatment Plant, Saint-Pierre-d'Exideuil, Nouvelle-Aquitaine

CIVRAY nouvelle is an advanced wastewater treatment plant located in Saint-Pierre-d'Exideuil, within the Vienne department of Nouvelle-Aquitaine, France. The facility serves a population of approximately 5,300 and has a designed capacity of 8,000 m³/day, with an average discharge volume of 945.51 m³/day. As an advanced treatment plant, CIVRAY nouvelle goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and EU standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent are required to provide secondary treatment, but this facility's advanced level indicates it likely discharges into a sensitive area requiring additional nutrient removal. The treated effluent is discharged into the local watershed, which ultimately drains into the Vienne River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and migratory fish species. The advanced treatment helps protect downstream water quality in this important river system.

The plant discharges into the Vienne River watershed, which flows into the Loire River, one of France's longest rivers. The Loire basin supports diverse aquatic ecosystems, including migratory fish such as Atlantic salmon and European eel. Advanced treatment at this facility helps reduce nutrient loading, protecting downstream water quality in this ecologically sensitive region.
