DAMMARTIN EN GOELE Wastewater Treatment Plant, Dammartin-en-Goële, France

The DAMMARTIN EN GOELE wastewater treatment plant is located in Dammartin-en-Goële, a commune in the Seine-et-Marne department of Île-de-France, France. The plant serves a population of approximately 4,307 residents and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 768.36 m³/day. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Seine River basin. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps reduce nutrient loading and protect downstream water quality.

The plant discharges into the local watershed within the Seine River basin, which ultimately drains into the English Channel. The Seine River and its tributaries support a variety of fish species, including salmon and trout, and are important for migratory birds. The advanced treatment at this plant helps minimize nutrient pollution, which can cause eutrophication in downstream estuaries and coastal zones.
