Bourgtheroulde Infreville Wastewater Treatment Plant, Grand Bourgtheroulde, Normandie

The Bourgtheroulde Infreville wastewater treatment plant is located in Grand Bourgtheroulde, in the Normandie region of France. It serves a population of approximately 3,050 people, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, away from coastal areas, and treats wastewater from the local community. 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. The designed capacity is 5,717 m³/day, while the current discharge volume is 544.11 m³/day, indicating that the plant operates well below its capacity. As a French facility, it operates under national regulations that implement the EU directive, ensuring high treatment standards. The treated effluent is discharged into a local watercourse that eventually drains into the Seine River basin, which flows into the English Channel. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems, including the Seine estuary and the marine environment of the Channel.

The plant discharges treated wastewater into a local watercourse within the Seine River basin. The Seine flows through Normandy and into the English Channel, supporting diverse aquatic life and providing important ecological services. The downstream environment includes the Seine estuary, a critical habitat for migratory fish and bird species. The advanced treatment level helps minimize nutrient and pollutant loads, protecting water quality in the river and coastal zone.
