LANEUVEVILLE LES LORQUIN Wastewater Treatment Plant | Advanced Treatment in Grand Est, France

The LANEUVEVILLE LES LORQUIN wastewater treatment plant is located in Laneuveville-lès-Lorquin, a commune in the Moselle department of the Grand Est region, France. The plant serves a population of approximately 4,350 residents, reflecting its role as a small-to-medium agglomeration facility within the regional wastewater infrastructure. 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 9,830 m³/day and a current discharge volume of 776.03 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local waterways that ultimately drain into the Rhine basin, contributing to the protection of downstream ecosystems. The advanced treatment level ensures high-quality effluent, supporting the ecological health of receiving waters and aligning with France's commitment to reducing nutrient pollution in sensitive areas.

The plant discharges into local streams that flow into the Sarre River, a tributary of the Moselle River, which joins the Rhine River before reaching the North Sea. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality in this ecologically sensitive transboundary river system.
