MEUILLEY Wastewater Treatment Plant, Meuilley, Bourgogne-Franche-Comté, France

The MEUILLEY wastewater treatment plant is located in the commune of Meuilley, within the Côte-d'Or department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,725 residents, classifying it as a small agglomeration under French and EU regulations. 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 sensitive areas. With a designed capacity of 6,000 m³/day and an average daily discharge of 486.14 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Treated effluent is discharged into local waterways that ultimately drain into the Saône River basin, a major tributary of the Rhône. This region is known for its vineyards and agricultural activity, making proper wastewater treatment essential for protecting downstream water quality and aquatic ecosystems.

The plant discharges into the local watershed, which flows into the Saône River and eventually the Rhône River before reaching the Mediterranean Sea. The surrounding area is part of the Burgundy wine region, where surface water quality is critical for both ecological health and agricultural use. The advanced treatment helps reduce nutrient loads, protecting downstream habitats from eutrophication.
