Damparis Wastewater Treatment Plant: Advanced Treatment in Bourgogne-Franche-Comté

The Damparis wastewater treatment plant is located in the commune of Damparis, within the Jura department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,416 residents, placing it in the small agglomeration category under French regulations. The plant is situated inland, away from coastal areas, and its operations are integrated into the regional water management infrastructure. The facility employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,500 m³/day and an average discharge volume of 431 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The plant's advanced treatment ensures high-quality effluent suitable for discharge into sensitive environments. The treated wastewater is discharged into local watercourses that ultimately flow into the Doubs River, a tributary of the Saône, which joins the Rhône River before reaching the Mediterranean Sea. The plant plays a key role in protecting the Doubs River basin from nutrient pollution and maintaining water quality for downstream ecosystems, including aquatic habitats and agricultural water use.

The plant discharges into the Doubs River basin, which flows into the Saône and then the Rhône River, eventually reaching the Mediterranean Sea. The Doubs River supports diverse aquatic life and is an important corridor for migratory fish species. Advanced treatment helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive watershed.
