Overview
ROUEN wastewater treatment plant serves Le Grand-Quevilly and the Rouen metropolitan area in Normandy, France. It treats wastewater from approximately 501,000 people, operating under the EU Urban Waste Water Treatment Directive.
The ROUEN wastewater treatment plant is located in Le Grand-Quevilly, a suburb of Rouen in the Normandy region of France. It serves a population of approximately 501,000 people, making it a large agglomeration under EU classification. The plant is part of the municipal wastewater infrastructure for the Rouen metropolitan area. As a large agglomeration in an EU member state, the plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires secondary treatment as a minimum, and for sensitive areas, tertiary treatment for nutrient removal. Given the population served, the plant likely provides at least secondary treatment, and may include advanced treatment to meet local environmental standards. The treated effluent is discharged into the Seine River, which flows through Rouen and continues to the English Channel. The Seine estuary is an ecologically important area, supporting diverse aquatic life and serving as a migratory corridor for fish. The plant's operations are critical for protecting water quality in the Seine and downstream coastal waters.
Environmental context
The plant discharges into the Seine River, which flows through Normandy and into the English Channel at the Seine estuary. The estuary is a dynamic ecosystem that supports diverse aquatic life, including fish and bird species, and is an important migratory corridor. The plant's treatment performance directly affects water quality in the lower Seine and the coastal zone, influencing nutrient loads and ecological health.
