Overview
LAGNY SUR MARNE ST THIBAULT DES VIGNES wastewater treatment plant serves over 310,000 people in Saint-Thibault-des-Vignes, Île-de-France, France. It operates under the EU Urban Waste Water Treatment Directive.
The LAGNY SUR MARNE ST THIBAULT DES VIGNES wastewater treatment plant is located in Saint-Thibault-des-Vignes, within the Île-de-France region of France. Serving a population of over 311,000, it is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is part of the municipal wastewater infrastructure managed by the Sietrem intercommunal syndicate. As a large agglomeration, the plant is required to provide secondary treatment as a minimum, with tertiary treatment expected if discharging into sensitive areas. The regulatory framework ensures compliance with EU standards for nutrient removal and water quality. The plant discharges treated wastewater into the Marne River, a major tributary of the Seine River. The Seine flows through Paris and eventually reaches the English Channel. The plant plays a crucial role in protecting the Marne and Seine river ecosystems from pollution, supporting aquatic life and downstream water quality.
Environmental context
The plant discharges into the Marne River, which flows into the Seine River and ultimately the English Channel. The Marne and Seine rivers support diverse aquatic ecosystems and are important for regional biodiversity. The plant's operations help mitigate nutrient loading and protect downstream habitats.
