Sohrewald Eiterhagen Wastewater Treatment Plant, Eiterhagen, Hessen, Germany

Sohrewald Eiterhagen is a wastewater treatment plant located in the village of Eiterhagen, part of the municipality of Söhrewald in the Landkreis Kassel district of Hessen, Germany. The plant serves a population of approximately 2,300 people, placing it in the small agglomeration category under German and EU regulations. As a German plant serving fewer than 10,000 population equivalents, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. For small agglomerations in inland areas, secondary treatment is typically mandated unless the receiving water body is designated as a sensitive area, in which case more stringent treatment may apply. The plant discharges treated effluent into local watercourses that ultimately drain into the Fulda River, a tributary of the Weser River system. The Weser flows northward through central Germany to the North Sea. The surrounding region is characterized by forested hills and agricultural land, and the local watershed supports diverse aquatic life and provides important ecosystem services.

The treated effluent from Sohrewald Eiterhagen flows into small streams within the Fulda River basin, which joins the Weser River and eventually reaches the North Sea. The local watershed is part of a mixed-use landscape with forests and agriculture, and the water bodies support fish populations and other aquatic organisms. The plant's discharge contributes to the overall water quality in the Weser system, which is managed under the EU Water Framework Directive to achieve good ecological status.
