CRAMANT Wastewater Treatment Plant, Cuis, Grand Est, France

CRAMANT is an advanced wastewater treatment plant located in Cuis, within the Épernay area of the Marne department in the Grand Est region of France. The plant serves a population of approximately 2,233 residents and is part of the municipal wastewater infrastructure for the local community. The plant operates with advanced treatment processes, meeting high standards for effluent quality. With a designed capacity of 2,500 m³/day and an actual discharge volume of 398.36 m³/day, the facility operates well below its capacity, indicating room for future growth. As a French plant, it complies with the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The treated effluent from CRAMANT is discharged into the local watershed, which ultimately drains into the Seine River basin and then 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.

CRAMANT discharges treated wastewater into the local water system, which flows into the Marne River, a major tributary of the Seine. The Seine River basin supports diverse aquatic life and is an important ecological corridor in northern France. The plant's advanced treatment helps reduce nutrient and pollutant loads, protecting downstream water quality and the sensitive estuarine environment of the Seine estuary.
