Loupershouse Wastewater Treatment Plant, Grand Est, France

The Loupershouse wastewater treatment plant is located in Loupershouse, a commune in the Moselle department of Grand Est, France. It serves a population of approximately 1,450 residents, classifying it as a small agglomeration under French regulations. The plant is situated near the A4 autoroute, east of Sarreguemines. The facility provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 2,500 cubic meters per day and currently discharges an average of 258.68 cubic meters per day, indicating significant spare capacity. The treated effluent is discharged into local waterways that ultimately drain into the Saar River basin, a tributary of the Moselle and Rhine rivers. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as a major migratory corridor for fish. The advanced treatment helps reduce nutrient loading into this transboundary river system.

The plant discharges into the local watershed that flows into the Saar River, a tributary of the Moselle River, which joins the Rhine River. The Rhine basin is a major European waterway supporting diverse aquatic ecosystems and migratory fish species. Advanced treatment at this plant helps minimize nutrient pollution, protecting downstream water quality in this ecologically sensitive transboundary basin.
