CHANGIS SUR MARNE is a wastewater treatment plant located in Changis-sur-Marne, a commune in the Seine-et-Marne department of north-central France. The facility serves a population of 2,240 and is part of the municipal infrastructure managed under French water regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,850 cubic meters per day and an average discharge volume of 399.61 cubic meters per day, the plant operates well within its capacity. Treated effluent is discharged into the local water system, ultimately flowing 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 the Île-de-France region. The plant's advanced treatment helps protect downstream water quality and the sensitive ecosystems of the Seine estuary.
Environmental context
The plant discharges into the Marne River, which flows into the Seine River and eventually reaches the English Channel via the Seine estuary. The Seine basin supports a variety of fish species and migratory birds, and the estuary is an ecologically sensitive area. Advanced treatment at this plant reduces nutrient and pollutant loads, helping to maintain water quality in this densely populated region.
