TRAINOU Wastewater Treatment Plant, Traînou, Centre-Val de Loire, France

TRAINOU is a wastewater treatment plant located in Traînou, a commune in the Centre-Val de Loire region of France. The plant serves a population of approximately 2,317 residents and operates with advanced treatment processes, ensuring high-quality effluent. The plant has a designed capacity of 3,000 cubic meters per day and currently discharges an average of 413.35 cubic meters per day. As a facility in France, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels for agglomerations of this size. Advanced treatment is typical for plants in sensitive areas to protect receiving water bodies. The treated effluent is discharged into local watercourses that eventually 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 downstream aquatic ecosystems and supports the ecological health of the region.

The plant discharges into local streams that are part of the Loire River basin. The Loire River flows westward through central France and empties into the Bay of Biscay (Atlantic Ocean). The watershed supports diverse aquatic life, including migratory fish species such as Atlantic salmon and European eel. Advanced treatment at this plant helps reduce nutrient loading and protects the ecological integrity of the downstream environment.
