The plant serves a population equivalent of 38,333, classifying it as a medium agglomeration under EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The treated effluent is discharged into the local watershed, which ultimately drains into the Marne River, a major tributary of the Seine. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic ecosystems and serving as a critical water resource for the region.

The plant discharges into the Marne River basin, which flows into the Seine River and eventually the English Channel. The Seine estuary and downstream coastal areas support diverse aquatic life and are important for fisheries and recreation. The region's water quality is managed under the EU Water Framework Directive, aiming to achieve good ecological status.
