SAINT LUPICIN Wastewater Treatment Plant, Coteaux du Lizon, France

The SAINT LUPICIN wastewater treatment plant is located in Coteaux du Lizon, within the Jura department of Bourgogne-Franche-Comté, France. It serves a population of 3,230 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. The plant has a designed capacity of 3,500 m³/day, with an average daily discharge volume of 576 m³. As a French facility, it operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations serving between 2,000 and 10,000 population equivalents, the directive requires secondary treatment, but this plant goes beyond with advanced treatment, likely due to the sensitivity of the receiving environment. The plant's capacity utilization is low, indicating ample reserve for future growth or seasonal peaks. The treated effluent is discharged into the local river system, which flows through the Jura region and eventually reaches the Rhône basin. The area is known for its karst landscapes and sensitive aquatic ecosystems, making advanced treatment crucial for protecting downstream water quality and biodiversity.

The plant discharges into the local watershed in the Jura region, part of the Rhône basin. The receiving water body ultimately drains to the Mediterranean Sea via the Rhône River. The area features karst geology and supports diverse aquatic life, including protected fish species. Advanced treatment helps minimize nutrient loading and protects downstream ecosystems.
