SAINT FLORENTIN Wastewater Treatment Plant, Saint-Florentin, Bourgogne-Franche-Comté

The SAINT FLORENTIN wastewater treatment plant is located in Saint-Florentin, a commune in the Yonne department of Bourgogne-Franche-Comté, France. The plant serves a population of 2,749 and has a designed capacity of 7,500 m³/day, with an average discharge volume of 490.42 m³/day. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Seine River basin. The plant plays a key role in protecting the water quality of the region's rivers and downstream ecosystems, including the Seine estuary and the English Channel.

The plant discharges into the local watercourse, part of the Seine River basin, which flows through the Paris Basin and into the English Channel. The watershed supports diverse aquatic life and is an important ecological corridor. Advanced treatment helps reduce nutrient loading, protecting downstream water bodies from eutrophication and maintaining biodiversity.
