CHAMPCUEIL Wastewater Treatment Plant, Champcueil, France - Advanced Treatment for 3,680 People

The CHAMPCUEIL wastewater treatment plant is located in Champcueil, a commune in the Essonne department of Île-de-France, France. It serves a population of approximately 3,680 people, classifying it as a small agglomeration under French regulations. The plant is situated near the Hôpital Georges Clemenceau and operates as part of the region's municipal wastewater infrastructure. 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. Its designed capacity is 6,700 m³ per day, with an actual discharge volume of 656.51 m³ per day, indicating significant spare capacity. The facility is operated within the regulatory framework of French water agencies, which enforce strict discharge standards to protect receiving water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Seine River basin. The Seine flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps minimize nutrient and pollutant loads, contributing to the ecological health of the Seine and its estuary.

The plant discharges into the local watershed, which is part of the Seine River basin. The Seine flows northwest through Paris and into the Seine Bay in the English Channel. This region supports diverse aquatic life, including fish species such as pike and perch, and provides critical habitat for migratory birds. The advanced treatment at Champcueil reduces the risk of eutrophication and protects downstream water quality in this densely populated and agriculturally active area.
