CHEVILLY Wastewater Treatment Plant, Chevilly, Centre-Val de Loire, France

The CHEVILLY wastewater treatment plant is located in Chevilly, a commune in the Loiret department of the Centre-Val de Loire region, France. The plant serves a population of approximately 3,000 residents and is part of the municipal wastewater infrastructure managed by local authorities. The plant provides advanced treatment, which goes 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 has a designed capacity of 3,000 m³/day and currently discharges a volume of 535.19 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The advanced treatment helps protect the ecological quality of the Loire and its tributaries, supporting diverse aquatic life and maintaining water quality for downstream communities.

The plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is a ecologically significant river, supporting diverse fish populations and migratory species. Advanced treatment at this plant helps reduce nutrient loading, protecting the river from eutrophication and preserving its ecological balance.
