Overview
Vieux-Manoir wastewater treatment plant in Normandy, France serves 1,150 people with secondary treatment. It discharges 205.16 m³/day and has a designed capacity of 2,300 m³/day.
The Vieux-Manoir wastewater treatment plant is located in the commune of Vieux-Manoir, in the Seine-Maritime department of Normandy, France. It serves a population of approximately 1,150 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, more than 10 km from the coast, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the minimum required by the EU UWWTD for freshwater discharges from agglomerations of this size. It has a designed capacity of 2,300 m³/day and currently treats an average daily volume of 205.16 m³, indicating significant spare capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse that ultimately drains into the Seine River basin. The Seine River flows through Normandy and into the English Channel, supporting diverse aquatic ecosystems and providing water for agriculture and industry. The plant's compliance with EU standards helps protect the downstream environment from nutrient pollution and other contaminants.
Environmental context
The plant discharges into a local stream that is part of the Seine River basin. The Seine River flows northward through Normandy and into the English Channel, supporting a variety of aquatic life and serving as a critical water resource. The downstream environment includes estuarine and coastal habitats that are ecologically sensitive, particularly for migratory fish species. Proper wastewater treatment is essential to prevent eutrophication and maintain water quality in the Seine estuary and the Channel.
