Overview
ROSNY SUR SEINE wastewater treatment plant serves Rosny-sur-Seine in Île-de-France, France. It handles a population equivalent of 93,750 under the EU Urban Waste Water Treatment Directive.
The ROSNY SUR SEINE wastewater treatment plant is located in Rosny-sur-Seine, a commune in the Yvelines department of Île-de-France, France. The facility serves a population equivalent of 93,750, classifying it as a large agglomeration under EU regulations. The plant is situated inland, approximately 50 km from the coast, and its operations are integral to the region's water management infrastructure. As a facility serving over 10,000 population equivalent, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum standard. For agglomerations of this size, the directive also requires appropriate treatment to meet quality standards before discharge into receiving waters. The plant's treatment processes are designed to comply with these regulatory requirements, ensuring effective pollutant removal. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Seine River basin. The Seine flows through the Paris region and into the English Channel, supporting diverse aquatic ecosystems. The plant plays a crucial role in protecting downstream water quality and the ecological health of the Seine estuary.
Environmental context
The plant discharges into the Seine River basin, which flows through Île-de-France and eventually reaches the English Channel. The Seine estuary supports a variety of fish and bird species, and the river is an important migratory corridor. The plant's operations help maintain water quality in this ecologically sensitive watershed.
