CHATEAUMEILLANT Route de Lignieres Wastewater Treatment Plant, Châteaumeillant, France

CHATEAUMEILLANT Route de Lignieres is an advanced wastewater treatment plant located in the commune of Châteaumeillant, in the Cher department of Centre-Val de Loire, France. The plant serves a population of approximately 1,793 residents, making it a small-scale facility within the region's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 2,000 population equivalent), the directive requires appropriate treatment, and the advanced level here ensures high-quality effluent. The designed capacity is 2,100 m³/day, with a reported discharge volume of 319.87 m³/day, indicating significant reserve 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 plant's advanced treatment helps protect the region's water quality and supports the ecological health of downstream aquatic environments.

The plant discharges into the local watershed within the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire basin supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps minimize nutrient and pollutant loads, protecting downstream water quality and habitats.
