Hohenlockstedt Wastewater Treatment Plant | Schleswig-Holstein, Germany

The Hohenlockstedt wastewater treatment plant is located in the town of Hohenlockstedt in Schleswig-Holstein, Germany. It serves a population of approximately 8,763 people, making it a medium-sized facility within the region's wastewater infrastructure. The plant is situated inland, more than 10 km from the coast, and plays a key role in managing municipal wastewater for the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 11,500 m³/day and an average discharge volume of 933.58 m³/day, the facility operates well within its capacity. This treatment level ensures high-quality effluent that meets stringent environmental standards. The treated wastewater is discharged into local water bodies that eventually drain into the North Sea via the Elbe River system. The plant's advanced treatment helps protect downstream aquatic ecosystems, including sensitive habitats in the Elbe estuary and the Wadden Sea, a critical area for migratory birds and marine life. By reducing nutrient loads, the facility contributes to the overall health of the North Sea coastal environment.

The plant discharges into local streams that flow into the Stör River, a tributary of the Elbe River. The Elbe carries the treated water to the North Sea, passing through the Wadden Sea, an ecologically sensitive intertidal zone that supports diverse bird populations and marine species. Advanced treatment at Hohenlockstedt helps minimize nutrient pollution, which is crucial for preventing eutrophication in these downstream waters.
