KA LAUTERBACH Wastewater Treatment Plant, Völklingen, Saarland, Germany

KA LAUTERBACH is a municipal wastewater treatment plant located in the Lauterbach district of Völklingen, in the Saarland region of southwestern Germany. The plant serves a population of approximately 2,800 residents and is designed to handle up to 3,000 cubic meters of wastewater per day, with an average discharge volume of 640.28 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies, aligning with Germany's strict national water quality standards. The treated effluent is discharged into local waterways that ultimately drain into the Saar River, a tributary of the Moselle, which flows into the Rhine and then the North Sea. The plant plays a key role in maintaining the ecological health of the Saar River basin, supporting aquatic life and downstream water quality in a region characterized by both urban and industrial activity.

The plant discharges into the local watershed that feeds the Saar River, a major tributary of the Moselle River, which flows into the Rhine and eventually the North Sea. The Saar basin supports diverse aquatic ecosystems and is an important corridor for migratory fish. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in a region with historical industrial impacts.
