SEPTMONTCEL Wastewater Treatment Plant, Septmoncel les Molunes, France

SEPTMONTCEL is a wastewater treatment plant located in Septmoncel les Molunes, in the Jura department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,100 residents, operating as a municipal facility within the region's water management infrastructure. The plant employs advanced treatment processes, meeting the highest standards under French regulations and the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 6,200 m³/day and a current discharge volume of 374.64 m³/day, the plant has ample capacity to accommodate future growth. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River basin via the Bienne River. This contributes to the ecological health of downstream water bodies, supporting aquatic biodiversity and water quality in the region.

The plant discharges into the Bienne River, a tributary of the Ain River, which flows into the Rhône River and eventually reaches the Mediterranean Sea. The watershed supports diverse aquatic life, including fish species such as brown trout and grayling, and is part of a region known for its karst landscapes and groundwater sensitivity.
