Overview
CHAMANT is a secondary wastewater treatment plant in Senlis, Hauts-de-France, France, serving 1,553 people with a designed capacity of 2,000 m³/day and an average discharge of 277 m³/day.
CHAMANT is a municipal wastewater treatment plant located at 97 Rue du Moulin Saint-Rieul in the Villevert quarter of Senlis, Oise, Hauts-de-France, France. The plant serves a population of 1,553 and has a designed capacity of 2,000 m³/day, with an average daily discharge of 277 m³/day, indicating a capacity utilization of about 14%. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size (under 10,000 population equivalent). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Oise River, a major tributary of the Seine River. The Seine flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and serving as a critical water resource for the region. The plant's operation helps protect downstream water quality and the ecological health of the Seine basin.
Environmental context
The plant discharges into the Oise River basin, which flows into the Seine River and eventually the English Channel. This watershed supports diverse aquatic life and is an important ecological corridor in northern France. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain water quality in the downstream river system and minimize eutrophication risks in the Seine estuary.
