Rahden Wastewater Treatment Plant - Nordrhein-Westfalen, Germany

The Rahden wastewater treatment plant is located in the town of Rahden, in the district of Minden-Lübbecke, Nordrhein-Westfalen, Germany. It serves a population of approximately 16,850 people, classifying it as a medium-sized agglomeration under EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet the requirements for sensitive areas, which are common in the region due to the ecological importance of local water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Weser River system. The Weser flows northward to the North Sea, passing through ecologically sensitive areas that support diverse aquatic life. The plant plays a key role in protecting downstream water quality.

The plant discharges into the local watershed, which is part of the Weser River basin. The Weser flows through Nordrhein-Westfalen and Lower Saxony before reaching the North Sea. This river system supports diverse aquatic habitats and is important for migratory fish species. The region's agricultural and urban runoff can impact water quality, making effective wastewater treatment essential for maintaining ecological balance.
