KA DORF IM WARNDT Wastewater Treatment Plant, Karlsbrunn, Saarland

KA DORF IM WARNDT is a wastewater treatment facility located in Karlsbrunn, a district of Großrosseln in the Saarland region of Germany. The plant serves a population of approximately 2,000 residents, making it a small-scale municipal treatment facility. It operates under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for wastewater collection and treatment. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU 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 2,000 cubic meters per day and currently treats an average daily flow of 529.60 cubic meters, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that eventually drain into the Saar River, a tributary of the Moselle and ultimately the Rhine. The Saar River basin supports diverse aquatic life and is an important ecological corridor in western Germany. The plant's advanced treatment helps maintain water quality in this region, which is characterized by forested hills and industrial history.

The plant discharges into small streams that flow into the Saar River, a major tributary of the Moselle River, which joins the Rhine near Koblenz. The Saar basin is ecologically sensitive, supporting fish species such as grayling and barbel, and is a key migratory route for aquatic organisms. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
