IGOVILLE Wastewater Treatment Plant, Pont-de-l'Arche, Normandie

The IGOVILLE wastewater treatment plant is located in Pont-de-l'Arche, within the Eure department of Normandie, France. It serves a population of approximately 2,202 residents, classifying it as a small agglomeration under French regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 1,950 m³/day and a current discharge volume of 392.83 m³/day, the facility operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Seine River and then the English Channel. The plant plays a role in protecting the Seine basin from nutrient pollution and supporting downstream aquatic ecosystems.

The plant discharges into the Seine River basin, which flows through Normandy into the English Channel. The Seine estuary is an ecologically sensitive area that supports diverse aquatic life, including migratory fish species. Effective secondary treatment helps reduce organic load and nutrient inputs, mitigating eutrophication risks in the downstream marine environment.
