Varanges Wastewater Treatment Plant: Advanced Treatment in Bourgogne-Franche-Comté

The Varanges wastewater treatment plant is located in the commune of Varanges, within the Côte-d'Or department of Bourgogne-Franche-Comté, France. It serves a small population of 816 residents, reflecting its role in a rural community. The plant is situated near the Moulin de Varanges along Rue du Moulin. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2000 m³/day and an actual discharge volume of 145.57 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Seine basin, contributing to the protection of downstream ecosystems. The advanced treatment ensures high-quality effluent, reducing nutrient loads and protecting sensitive receiving waters in the region.

The plant discharges into local streams that flow into the Seine River basin, which drains into the English Channel. The region's water bodies support diverse aquatic life and are important for agriculture and biodiversity. Advanced treatment helps minimize eutrophication risks and protects downstream habitats.
