Steinbusch Wastewater Treatment Plant, Würselen, Nordrhein-Westfalen

Steinbusch is a wastewater treatment plant located in Würselen, within the Städteregion Aachen in Nordrhein-Westfalen, Germany. The facility serves a population of around 24,039, classifying it as a medium agglomeration under EU regulations. As a German plant, Steinbusch operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. Compliance with national and EU standards is expected. The treated effluent from Steinbusch is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway, supporting diverse aquatic life and providing drinking water for millions. The plant's operations help protect downstream ecosystems and water quality in the region.

Steinbusch discharges into local streams that flow into the Rur River, a tributary of the Meuse River, which eventually reaches the North Sea. The Rur and Meuse basins support diverse aquatic habitats and are important for regional biodiversity. The plant's treatment helps maintain water quality in these sensitive river systems.
