AUBIGNY SUR NERE Le moulin des filles Wastewater Treatment Plant, Aubigny-sur-Nère, France

AUBIGNY SUR NERE Le moulin des filles is an advanced wastewater treatment plant located in Aubigny-sur-Nère, in the Centre-Val de Loire region of France. The plant serves a population of 4,556, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 5,650 m³/day and an average discharge volume of 812.78 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As a French facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain 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 the ecological health of the receiving waters, supporting aquatic life and downstream water quality.

The plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is known for its diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and supporting the ecological balance of the river system.
