JOINVILLE Wastewater Treatment Plant, Joinville, Grand Est, France

The JOINVILLE wastewater treatment plant is located in Joinville, a commune in the Haute-Marne department of the Grand Est region, France. The facility serves a population of approximately 3,000 residents and is situated along the Marne River, reflecting its role in managing local municipal wastewater. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 m³/day and a current discharge volume of 535.19 m³/day, the plant operates well within its capacity, ensuring effective treatment of wastewater. Treated effluent is discharged into the Marne River, which flows through the region and eventually joins the Seine River near Paris, ultimately reaching the English Channel. The plant's advanced treatment helps protect the Marne's water quality, supporting aquatic life and downstream ecosystems in this ecologically sensitive area.

The plant discharges into the Marne River, a major tributary of the Seine River system. The Marne flows through the Grand Est region and downstream to the Seine, which empties into the English Channel. This watershed supports diverse aquatic habitats and is important for regional biodiversity. The advanced treatment at JOINVILLE helps reduce nutrient and pollutant loads, safeguarding the river's ecological health.
