Overview
Sterup wastewater treatment plant in Schleswig-Holstein, Germany, serves 1,010 people with advanced treatment. The facility is closed but historically discharged into the Geltinger Bucht coastal area.
Sterup wastewater treatment plant is located in the municipality of Sterup, in the district of Schleswig-Flensburg, Schleswig-Holstein, Germany. The plant served a population of 1,010 and had a designed capacity of 2,100 cubic meters per day, with an average discharge volume of 255.61 cubic meters per day. The facility is currently closed. As a German plant, it operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive coastal areas. The plant's advanced treatment level indicates it was equipped to remove nutrients such as nitrogen and phosphorus, meeting stringent standards for Baltic Sea protection. The plant discharged into the Geltinger Bucht, a bay of the Baltic Sea. This coastal environment is ecologically sensitive, supporting diverse marine life and serving as a habitat for fish and bird species. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to eutrophication from nutrient inputs.
Environmental context
The plant's treated effluent entered the Geltinger Bucht, a coastal inlet of the Baltic Sea in Schleswig-Holstein. The Baltic Sea is a brackish water body with restricted circulation, making it highly susceptible to nutrient pollution. Advanced treatment at this plant helped reduce nitrogen and phosphorus loads, protecting the bay's seagrass beds, fish spawning grounds, and migratory bird populations. The region's coastal waters are part of a larger ecosystem that includes the Fehmarn Belt and the western Baltic Sea.
Frequently asked questions
The plant is located at Ehrfelder Weg, Sterup, in the district of Schleswig-Flensburg, Schleswig-Holstein, Germany, near the Geltinger Bucht coast.
The plant served a population of 1,010 people, typical of a small agglomeration in rural Schleswig-Holstein.
The plant discharged treated effluent into the Geltinger Bucht, a coastal bay of the Baltic Sea, after advanced treatment to remove nutrients.
As a German plant discharging into a coastal area, it was subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas like the Baltic Sea to prevent eutrophication.
For small agglomerations in Germany, secondary treatment is standard, but plants near sensitive coastal areas like the Baltic Sea often require advanced treatment to meet nutrient reduction targets.
