Jougne Wastewater Treatment Plant: Advanced Treatment in Bourgogne-Franche-Comté

The Jougne wastewater treatment plant is located in the commune of Jougne, in the Doubs department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,200 residents and has a designed capacity of 4,400 m³ per day, with an average discharge volume of 392.48 m³ per day. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant operates under French regulations that implement the directive, ensuring high effluent quality. The treated wastewater is discharged into the local watershed, which ultimately drains into the Doubs River, a tributary of the Saône, then the Rhône, and finally the Mediterranean Sea. The plant plays a key role in protecting the Doubs River and downstream ecosystems from nutrient pollution and other contaminants.

The Jougne plant discharges into the Doubs River basin, which flows through the Jura Mountains and into the Saône River, a major tributary of the Rhône. The Rhône drains into the Mediterranean Sea. The Doubs River supports diverse aquatic life, including fish species such as brown trout and grayling. Advanced treatment at the plant helps reduce nutrient loading, which is critical for preventing eutrophication in downstream water bodies and maintaining water quality in this ecologically sensitive region.
