Overview
Suderhastedt wastewater treatment plant in Schleswig-Holstein, Germany, serves a small population of 800 with secondary treatment. The plant is now closed.
Suderhastedt wastewater treatment plant is located in the municipality of Süderhastedt, in the district of Dithmarschen, Schleswig-Holstein, Germany. The plant served a small population of 800 people and is now closed. As a small agglomeration, it operated under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for inland freshwater discharges. The plant had a designed capacity of 2160 cubic meters per day and a discharge volume of 202.46 cubic meters per day. The treated effluent was discharged into local watercourses that drain into the North Sea via the Elbe river system.
Environmental context
The plant's discharge likely entered small streams in the Dithmarschen region, which flow into the Elbe estuary and ultimately the North Sea. The area is part of the Wadden Sea ecosystem, a critical habitat for migratory birds and marine life. The plant's secondary treatment would have reduced organic pollutants, but nutrient removal may have been limited, potentially contributing to eutrophication in the sensitive coastal environment.
