MOUSSEAUX LES BRAY Wastewater Treatment Plant, Saint-Sauveur-lès-Bray, France

MOUSSEAUX LES BRAY is an advanced wastewater treatment plant located in Saint-Sauveur-lès-Bray, within the Seine-et-Marne department of north-central France. The facility serves a population of approximately 3,933, classifying it as a small to medium agglomeration under French regulations. It is situated inland, away from coastal areas, and its operations are part of the broader water management infrastructure for the region. 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 5,000 m³/day and an average discharge volume of 701.64 m³/day, the facility operates well within its capacity, ensuring effective treatment of incoming wastewater. The advanced treatment level likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into local water bodies that ultimately drain into the Seine River basin, which flows through Paris and into the English Channel. This discharge contributes to the overall water quality of the Seine watershed, supporting aquatic ecosystems and downstream uses. The plant's advanced treatment helps minimize environmental impact on the river system.

The plant discharges into the Seine River basin, which flows northwest through the Paris region and empties into the English Channel. The Seine supports diverse aquatic life and is an important ecological corridor for migratory fish species. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality in the river and estuary.
