Plettenberg Wastewater Treatment Plant | Serving Plettenberg, Nordrhein-Westfalen

The Plettenberg wastewater treatment plant is located in the town of Plettenberg, in the Märkischer Kreis district of Nordrhein-Westfalen, Germany. It serves a population of around 29,262 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a German facility, the plant operates under 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 national standards set by the German Water Resources Act (Wasserhaushaltsgesetz) and state-level regulations. The treated wastewater is discharged into the Lenne River, a tributary of the Ruhr, which flows into the Rhine and ultimately the North Sea. The plant plays a key role in protecting the water quality of the Lenne and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Lenne River, which flows into the Ruhr and then the Rhine, eventually reaching the North Sea. The Lenne watershed supports diverse aquatic habitats and is important for regional biodiversity. Downstream, the Rhine is a major European waterway with significant ecological and economic value, requiring stringent pollution control.
