Vernou-sur-Brenne La Justice Wastewater Treatment Plant, Centre-Val de Loire

Vernou-sur-Brenne La Justice is a wastewater treatment plant located in Vernou-sur-Brenne, a commune in the Indre-et-Loire department of the Centre-Val de Loire region, France. The plant serves a population of approximately 3,450 residents and has a design capacity of 10,000 cubic meters per day, indicating it is sized to accommodate future growth or seasonal variations. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant's discharge volume is reported at 615.47 m³/day, well below its design capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River flows into the Atlantic Ocean, and its basin supports diverse aquatic ecosystems, including migratory fish species. The plant's advanced treatment helps minimize nutrient loading and protect downstream water quality.

The plant discharges into the Brenne River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and migratory fish such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient pollution, helping to protect the Loire's water quality and its downstream estuary and coastal zone in the Bay of Biscay.
