KA Quierschied Wastewater Treatment Plant, Sulzbach/Saar, Saarland, Germany

KA Quierschied is a municipal wastewater treatment plant located in Sulzbach/Saar, within the Saarland region of Germany. The plant serves a population of approximately 26,100 people, classifying it as a medium-sized agglomeration under EU regulations. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet the stringent effluent standards set by German water law, ensuring compliance with national and EU environmental regulations. The treated wastewater from KA Quierschied is discharged into the local water system, which ultimately drains into the Saar River, a tributary of the Moselle and then the Rhine. This river network supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in the Saar basin.

The plant discharges into the local watershed that flows into the Saar River, a major tributary of the Moselle River, which in turn joins the Rhine River before reaching the North Sea. The Saar basin supports diverse aquatic ecosystems and is used for recreation and drinking water supply downstream. The plant's operations help maintain water quality standards in this ecologically sensitive river system.
