DAMPIERRE_RANCHOT Wastewater Treatment Plant, Ranchot, Bourgogne-Franche-Comté

DAMPIERRE_RANCHOT is a municipal wastewater treatment plant located at 8 Rue du Rondelot in Ranchot, a commune in the Jura department of Bourgogne-Franche-Comté, France. The plant serves a population of approximately 2,100 people and has a design capacity of 4,000 m³ per day, with an average daily discharge of 374.64 m³. 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. As a French facility, it operates under national regulations transposing the EU directive, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into the local water system, 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 water quality of the Doubs basin, which supports diverse aquatic life and is used for recreation and agriculture downstream.

The plant's discharge enters the local watershed, which flows into the Doubs River, a major tributary of the Saône River. The Saône joins the Rhône, which empties into the Mediterranean Sea. The Doubs basin is ecologically sensitive, supporting fish species such as brown trout and grayling, and the river is used for fishing and water sports. Advanced treatment at this plant helps reduce nutrient loading, preventing eutrophication in downstream water bodies.
