Willingshausen _ Wasenberg Wastewater Treatment Plant, Wasenberg, Hessen, Germany

Willingshausen _ Wasenberg is a former wastewater treatment plant located in Wasenberg, a district of Willingshausen in the Schwalm-Eder-Kreis district of Hessen, Germany. The plant served a small community of approximately 1,340 people and was designed with a capacity of 2,400 cubic meters per day. The plant provided 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 to protect sensitive water bodies. The plant is now closed, and its wastewater is likely diverted to another facility in the region. The plant's discharge would have entered the local watershed, eventually draining into the Schwalm River, a tributary of the Eder, which flows into the Fulda and then the Weser River. The Weser ultimately discharges into the North Sea. The region is characterized by agricultural land and small settlements, and the plant's advanced treatment helped protect local streams from nutrient pollution.

The plant's treated effluent would have entered the local drainage network, flowing into the Schwalm River, a tributary of the Eder. The Eder joins the Fulda, which forms the Weser River, discharging into the North Sea. The watershed supports diverse aquatic life and is used for agriculture and recreation. Advanced treatment at this plant helped reduce nutrient loads, protecting downstream ecosystems from eutrophication.
