ATHIS DE L ORNE Wastewater Treatment Plant, Athis-Val-de-Rouvre, Normandie

The ATHIS DE L ORNE wastewater treatment plant is located in Athis-Val-de-Rouvre, within the Orne department of Normandie, France. This facility serves a population of 1,295 and is part of the municipal wastewater infrastructure for the commune. 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. Its designed capacity of 2,100 m³/day indicates it can handle peak flows, while the current discharge volume of 231 m³/day suggests ample reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel via the Orne River and its estuary. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into the Orne River basin, which flows northward through Normandie and into the Baie de Seine and the English Channel. The downstream environment includes the Orne estuary, a ecologically sensitive area that supports diverse aquatic life and migratory fish species. Advanced treatment at this plant helps reduce nutrient loading and protects the estuarine and coastal waters.
