FRAHIER ET CHATEBIER Wastewater Treatment Plant, Chenebier, France

FRAHIER ET CHATEBIER is a wastewater treatment plant located in Chenebier, in the Bourgogne-Franche-Comté region of France. It serves a population of 1,818 people, classifying it as a small agglomeration under French regulations. The plant is situated in the rural commune of Chenebier, near the city of Lure in the Haute-Saône department. 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 2,300 m³/day, and it currently discharges 324.33 m³/day of treated wastewater. As a small inland facility, it operates under French national regulations that implement the EU directive, ensuring compliance with stringent effluent standards. The treated effluent is discharged into local watercourses that eventually drain into the Saône River, a major tributary of the Rhône. The Rhône flows into the Mediterranean Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Saône basin, which support diverse fish populations and serve as an important migratory corridor for species like the European eel.

The plant discharges into local streams that feed the Saône River, which flows into the Rhône and ultimately the Mediterranean Sea. The Saône basin is ecologically sensitive, supporting diverse aquatic life including fish species such as pike and perch. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in this important European river system.
