Wildeck _ Obersuhl Wastewater Treatment Plant, Gerstungen, Thüringen

The Wildeck _ Obersuhl wastewater treatment plant is located in the Untersuhl district of Gerstungen, in the Wartburgkreis region of Thüringen, Germany. The plant serves a population of approximately 4,000 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a German facility, the plant operates under the national implementation of the EU UWWTD (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, typically secondary treatment, to protect receiving water bodies. The plant's treatment process and capacity are consistent with these regulatory standards. The treated effluent is discharged into local watercourses that drain into the Werra River, a tributary of the Weser River system, which ultimately flows into the North Sea. The plant plays a key role in maintaining water quality in the region's sensitive aquatic ecosystems, supporting biodiversity and preventing eutrophication in downstream waters.

The plant discharges into local streams that feed the Werra River, part of the Weser basin, which flows into the North Sea. The Werra River supports diverse aquatic life and is an important corridor for migratory fish. Protecting this watershed from nutrient pollution is critical for maintaining ecological balance in the downstream estuary and coastal waters.
