Chatenois les Forges Wastewater Treatment Plant - Châtenois-les-Forges, France

Chatenois les Forges is a wastewater treatment plant located in Châtenois-les-Forges, a commune in the Territoire-de-Belfort department of Bourgogne-Franche-Comté, France. The plant serves a population of approximately 2,460 people, classifying it as a small agglomeration under French and EU 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. With a designed capacity of 3,300 m³/day and an average discharge volume of 438.86 m³/day, the plant operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Doubs River, a tributary of the Saône, and then into the Rhône River before reaching the Mediterranean Sea. The plant plays a key role in protecting the water quality of these downstream water bodies and supporting the ecological health of the region.

The plant discharges into the local watershed that flows into the Doubs River, a major tributary of the Saône River, which joins the Rhône River and empties into the Mediterranean Sea. The Doubs River supports diverse aquatic life and is an important ecological corridor in the region. Advanced treatment helps minimize nutrient and pollutant loads, protecting downstream ecosystems and water quality.
