Villedieu sur Indre L Allemagne is a wastewater treatment plant located in Niherne, a commune in the Indre department of the Centre-Val de Loire region, France. The plant serves a population of approximately 4,200 and has a designed capacity of 6,000 cubic meters per day, with an average discharge volume of about 749 cubic meters per day. It is situated along the D 67 road, near the Indre River, and operates under French national regulations implementing the EU Urban Waste Water Treatment Directive. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant's capacity utilization appears moderate, indicating it can accommodate future growth or seasonal variations. As a facility in the Loire-Brittany basin, it must comply with local water quality objectives set by the Agence de l'Eau Loire-Bretagne. The treated effluent is discharged into the Indre River, a tributary of the Loire River, which ultimately flows into the Atlantic Ocean. The Indre River supports diverse aquatic life and is part of a regional ecological network. By providing advanced treatment, the plant helps reduce nutrient loads and protect downstream water quality, including the Loire estuary and its associated wetlands.
Environmental context
The plant discharges into the Indre River, which flows into the Loire River, one of France's major rivers, before reaching the Atlantic Ocean. The Loire basin is ecologically significant, supporting migratory fish species and diverse riparian habitats. Advanced treatment at this plant helps minimize nutrient pollution, which is critical for preventing eutrophication in downstream waters, including the Loire estuary, a region of high ecological value.
Frequently asked questions
