Nentershausen Wastewater Treatment Plant, Weißenhasel, Hessen, Germany

The Nentershausen wastewater treatment plant is located in the Weißenhasel district of Nentershausen, in the Landkreis Hersfeld-Rotenburg district of Hessen, Germany. It served a population of approximately 1,742 people, placing it in the small agglomeration category under German and EU regulations. The plant provided secondary treatment, which is the standard biological treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The design capacity was 2,500 cubic meters per day, with an average discharge volume of about 441 cubic meters per day. The facility is now closed and no longer operational. The plant's treated effluent was discharged into a local water body within the Weser river basin, which ultimately drains into the North Sea. The surrounding region is rural and characterized by forested hills and small streams, supporting local aquatic ecosystems.

The plant discharged into a small tributary of the Weser river system, which flows through central Germany to the North Sea. The local watershed supports diverse freshwater habitats, including fish spawning grounds and invertebrate communities. The Weser estuary and coastal North Sea are ecologically sensitive areas with migratory bird populations and marine life.
