Overview
CHALONS EN CHAMPAGNE wastewater treatment plant serves Châlons-en-Champagne in Grand Est, France. It treats wastewater for nearly 100,000 people under EU regulations.
The CHALONS EN CHAMPAGNE wastewater treatment plant is located in Châlons-en-Champagne, in the Grand Est region of France. Serving a population of approximately 100,000, it is a significant municipal facility in the Marne department. The plant is situated near the Marne River, which flows through the city and ultimately joins the Seine River basin. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is expected to provide secondary treatment at a minimum, with tertiary treatment required if the receiving waters are designated as sensitive areas. The plant's capacity and treatment processes are designed to meet these regulatory standards, ensuring compliance with French and European water quality objectives. The treated effluent is discharged into the Marne River, a tributary of the Seine, which flows northwest through the Paris Basin and into the English Channel. The plant plays a crucial role in protecting the Marne River's water quality, supporting aquatic life and downstream ecosystems, including the Seine estuary and the marine environment of the English Channel.
