MORGNY LA POMMERAIE Wastewater Treatment Plant, Normandy, France

MORGNY LA POMMERAIE is an advanced wastewater treatment plant located in Morgny-la-Pommeraye, a commune in the Seine-Maritime department of Normandy, France. The plant serves a population of approximately 1,500 residents, reflecting its role in a small rural agglomeration. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,500 m³/day, and it currently discharges 267.6 m³/day of treated wastewater, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Seine River basin and the English Channel. By providing advanced treatment, the plant helps protect downstream aquatic ecosystems and supports the ecological health of the Normandy region.

The plant discharges into small streams that flow into the Seine River, which empties into the English Channel. The Seine estuary and its adjacent coastal waters are ecologically sensitive areas that support diverse aquatic life, including migratory fish species. Advanced treatment reduces nutrient and pollutant loads, mitigating eutrophication risks in the downstream marine environment.
