KA PRIMSTAL Wastewater Treatment Plant, Nonnweiler, Saarland, Germany

KA PRIMSTAL is a municipal wastewater treatment plant located in the Primstal district of Nonnweiler, in the Saarland region of Germany. The plant serves a population of approximately 2,400 residents, classifying it as a small agglomeration under EU regulations. As a German facility, KA PRIMSTAL operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater bodies. For small agglomerations like this, appropriate treatment ensures compliance with national water quality standards. The plant discharges treated wastewater into local waterways that ultimately drain into the Saar River basin, a tributary of the Moselle and Rhine systems. This region supports diverse aquatic life and contributes to the overall health of the Rhine watershed.

KA PRIMSTAL discharges into local streams that flow into the Prims River, a tributary of the Saar River. The Saar joins the Moselle, which flows into the Rhine River before reaching the North Sea. The local watershed supports aquatic ecosystems typical of the Saarland region, including fish species such as brown trout and grayling. Proper treatment is essential to protect these habitats from nutrient pollution.
