Beaucourt Wastewater Treatment Plant - Bourgogne-Franche-Comté, France

The Beaucourt wastewater treatment plant is located in Beaucourt, a commune in the Territoire-de-Belfort department of Bourgogne-Franche-Comté, France. It serves a population of approximately 4,725 people, classifying it as a small to medium agglomeration under French regulations. The plant 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. Its designed capacity is 7,000 m³/day, with an actual discharge volume of 842.93 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône basin via the Doubs and Saône rivers. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Saône River and its tributaries, which support diverse fish populations and migratory species.

The plant discharges into the local watercourse, part of the Doubs River watershed, which flows into the Saône River, a major tributary of the Rhône. The Rhône eventually reaches the Mediterranean Sea. The region's aquatic ecosystems support species such as the European eel and various freshwater fish, making advanced treatment important for maintaining water quality and biodiversity.
