Overview
CHEVANNES wastewater treatment plant in Chevannes, Bourgogne-Franche-Comté, France, serves about 2,500 people with advanced treatment. It discharges 452 m³/day of treated effluent, operating under EU Urban Waste Water Treatment Directive standards.
The CHEVANNES wastewater treatment plant is located in the commune of Chevannes, within the Yonne department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,500 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated in a rural inland setting, contributing to local water quality management. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 2,500 m³/day and an actual discharge volume of 452 m³/day, the plant operates well below its capacity, indicating room for future growth. As a French municipal plant, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size, and the plant exceeds this requirement with advanced treatment. The treated effluent is discharged into local watercourses that eventually drain into the Yonne River, a tributary of the Seine. The Seine basin supports diverse aquatic life and is ecologically sensitive, particularly downstream in the Seine estuary and the English Channel. The plant's advanced treatment helps protect these downstream ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant discharges into local streams that flow into the Yonne River, a major tributary of the Seine. The Seine River basin is a densely populated and agriculturally intensive region, making nutrient management critical. Downstream, the Seine estuary and the English Channel support important fisheries and migratory bird populations. Advanced treatment at this plant reduces the risk of eutrophication and protects aquatic habitats in the broader Seine watershed.
