Longeville-lès-Saint-Avold DUF is an advanced wastewater treatment facility located in Longeville-lès-Saint-Avold, Moselle, in the Grand Est region of France. The plant serves a population of approximately 5,400 residents and has a designed capacity of 7,150 m³/day, with an actual discharge volume of 963.35 m³/day. As an advanced treatment plant, it goes beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent. The plant's advanced level indicates nutrient removal or other tertiary processes, aligning with France's implementation of the directive for sensitive areas. The plant discharges treated wastewater into the local water system, which ultimately drains into the Rosselle River, a tributary of the Saar, then the Moselle, and finally the Rhine. This river network supports diverse aquatic life and is part of the larger Rhine basin, an ecologically significant region in Western Europe.
Environmental context
The plant's treated effluent enters the Rosselle River, which flows into the Saar, then the Moselle, and eventually the Rhine River. The Rhine basin is a major European watershed supporting diverse aquatic ecosystems and migratory fish species. The advanced treatment level helps protect downstream water quality in this sensitive river network.
