The LONGUEVILLE wastewater treatment plant is located in Longueville, a commune in the Seine-et-Marne department of Île-de-France, France. The facility serves a population of approximately 4,110 residents and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As a plant in France, LONGUEVILLE operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment. For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and France's national regulations often mandate advanced treatment in sensitive areas to protect water quality. The treated wastewater is discharged into local watercourses that eventually flow into the Seine River basin, which drains into the English Channel. The plant plays a key role in protecting the region's water resources and supporting the ecological health of downstream environments, including the Seine estuary and marine areas.
Environmental context
The plant discharges into the Seine River basin, which flows through Île-de-France and eventually reaches the English Channel. The Seine supports diverse aquatic life and is an important ecological corridor. Advanced treatment helps reduce nutrient loads, protecting downstream waters from eutrophication and maintaining water quality for both human use and biodiversity.
