PATAY 2 Wastewater Treatment Plant, Villeneuve-sur-Conie, France

PATAY 2 is an advanced wastewater treatment plant located in Villeneuve-sur-Conie, within the Centre-Val de Loire region of France. The plant serves a population of 2,400, classifying it as a small agglomeration under French and EU regulations. Its designed capacity is 3,000 cubic meters per day, with an average discharge volume of 428.16 cubic meters per day, indicating ample headroom for future growth. As an advanced treatment facility, PATAY 2 goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant operates under France's national water law, which transposes EU directives and requires permits for discharge quality and quantity. The plant's compliance with advanced treatment standards suggests rigorous oversight. The treated effluent from PATAY 2 is discharged into the local watershed, which drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Loire's diverse fish populations and migratory species, by reducing nutrient loading and maintaining water quality.

PATAY 2 discharges into the local watercourse, which is part of the Loire River basin. The Loire River flows through central France before emptying into the Atlantic Ocean near Saint-Nazaire. The basin supports diverse aquatic life, including Atlantic salmon and European eel, and is an important migratory corridor. Advanced treatment at the plant helps minimize eutrophication risks and protects the ecological health of the downstream river and estuary.
