Wetter Albringhausen Wastewater Treatment Plant, Wetter (Ruhr), Germany

Wetter Albringhausen is a wastewater treatment plant located in the city of Wetter (Ruhr), in the Ennepe-Ruhr-Kreis district of Nordrhein-Westfalen, Germany. The plant serves a small population of 1,981 and has a designed capacity of 4,640 cubic meters per day, with an average discharge volume of 501.34 m³/day. The plant provides advanced treatment, which goes beyond the secondary treatment required 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. The treated effluent is discharged into the local watershed, which ultimately drains into the Ruhr River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as a vital waterway for the region.

The plant discharges into the Ruhr River catchment, which flows into the Rhine River and eventually the North Sea. The Ruhr and Rhine rivers support diverse aquatic ecosystems, including fish species such as salmon and eel. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in this densely populated and industrialized region.
