Its designed capacity of 6,000 m³/day accommodates current flows with a utilization rate of about 16%. The plant discharges treated wastewater into local watercourses that ultimately drain into the Seine River basin. 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 advanced treatment helps protect downstream water quality and ecological health.
Environmental context
The plant discharges into the Yonne River, a tributary of the Seine, which flows through the Paris Basin and into the English Channel. The Seine estuary supports migratory fish species such as Atlantic salmon and eel, and the river system is ecologically sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication in downstream waters.
