VILLE DU PONT Wastewater Treatment Plant, Pays-de-Montbenoît, France

VILLE DU PONT is an advanced wastewater treatment plant located in Ville-du-Pont, within the commune of Pays-de-Montbenoît in the Doubs department of Bourgogne-Franche-Comté, France. The plant serves a population of approximately 4,300 people, classifying it as a small to medium agglomeration under EU regulations. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 3,000 m³/day and currently discharges 767 m³/day of treated wastewater. The treated effluent is discharged into a local watercourse that eventually flows into the Doubs River, a tributary of the Saône, which joins the Rhône before reaching the Mediterranean Sea. The plant's advanced treatment helps protect the aquatic ecosystem of the Doubs River and downstream water bodies from nutrient pollution and other contaminants.

The plant discharges into a local stream that feeds the Doubs River, a major waterway in the Bourgogne-Franche-Comté region. The Doubs River flows through the Jura Mountains and eventually joins the Saône River, which is part of the Rhône basin draining into the Mediterranean Sea. The watershed supports diverse aquatic life, including fish species such as brown trout and grayling, and is an important ecological corridor in the region. Advanced treatment at the plant helps maintain water quality in this sensitive river system.
