Les Moussières Wastewater Treatment Plant - Advanced Treatment in Jura, France

Les Moussières wastewater treatment plant is located in the commune of Les Moussières in the Jura department of Bourgogne-Franche-Comté, France. The plant serves a population of approximately 1,580 residents and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to meet secondary treatment standards, but it goes beyond with advanced treatment. The designed capacity of 1,100 m³/day and current discharge volume of 281.87 m³/day indicate ample capacity for current loads. The treated effluent is discharged into local watercourses that eventually drain into the Rhône basin, contributing to the water quality of downstream ecosystems. The plant's advanced treatment helps protect sensitive aquatic environments in the Jura region.

The plant discharges into small streams that feed the Bienne River, a tributary of the Ain River, which flows into the Rhône River and ultimately the Mediterranean Sea. The Jura region is known for its karst landscapes and sensitive groundwater systems, making advanced treatment crucial for protecting local biodiversity and downstream water quality.
