Overview
Noyers-sur-Cher Les Roches is a secondary wastewater treatment plant in Noyers-sur-Cher, Centre-Val de Loire, France. It serves a population of 986 and has a designed capacity of 2,900 m³/day.
Noyers-sur-Cher Les Roches is a wastewater treatment plant located in the commune of Noyers-sur-Cher, within the Loir-et-Cher department of the Centre-Val de Loire region, France. The plant serves a small population of approximately 986 residents, reflecting its role in a rural or peri-urban setting. It is situated inland, away from coastal areas, and its operations are part of the local municipal infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant's designed capacity is 2,900 m³/day, and the current discharge volume is 175.90 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Cher River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and migratory fish species. The plant's operations help protect the water quality of the Cher and Loire rivers, contributing to the overall health of the Loire Valley ecosystem.
Environmental context
The plant discharges into the Cher River, a major tributary of the Loire River. The Loire basin is one of France's largest watersheds, supporting diverse aquatic ecosystems and migratory fish such as Atlantic salmon and European eel. The region is known for its agricultural landscapes and sensitive riverine habitats, making effective wastewater treatment crucial for maintaining water quality and ecological balance.
