COUSANCE Wastewater Treatment Plant, Cousance, Bourgogne-Franche-Comté, France

COUSANCE is a wastewater treatment plant located in Cousance, a commune in the Jura department of Bourgogne-Franche-Comté, France. The plant serves a population of 3,910 and is designed with a capacity of 6,000 m³ per day, currently discharging 697.54 m³ per day. It provides advanced treatment, ensuring high-quality effluent before discharge. As a French wastewater facility, COUSANCE operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent and more stringent treatment in sensitive areas. France implements this directive through national regulations, requiring permits and regular monitoring. The plant's advanced treatment level suggests it may be in a sensitive catchment or subject to local environmental requirements. The treated effluent from COUSANCE is discharged into the local water system, which ultimately drains into the Rhône basin via the Seille River and the Saône River. This waterway supports diverse aquatic life and is part of a larger network that flows to the Mediterranean Sea. The plant's operation helps protect downstream water quality and ecological health.

COUSANCE discharges into the local watershed, which flows into the Seille River, a tributary of the Saône River, part of the Rhône basin. The Rhône eventually reaches the Mediterranean Sea. The region's aquatic ecosystems rely on clean water, and the plant's advanced treatment helps reduce nutrient and pollutant loads, supporting biodiversity in the downstream rivers and coastal zone.
