Overview
Dagebull wastewater treatment plant in Dagebüll-Hafen, Schleswig-Holstein, Germany, serves 1,024 people with advanced treatment. The facility is closed but discharged 259.15 cubic meters per day into the North Sea coastal environment.
Dagebull is a wastewater treatment plant located in Dagebüll-Hafen, a village in the district of Nordfriesland, Schleswig-Holstein, Germany. The plant served a population of 1,024 and had a designed capacity of 2,000 cubic meters per day, with an average discharge volume of 259.15 cubic meters per day. It is situated near the North Sea coast, within 10 kilometers of the shoreline. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive coastal waters. Although the facility is now closed, its operational history reflects the high standards applied to wastewater management in the Wadden Sea region. The treated effluent was discharged into the North Sea, a sensitive marine ecosystem that includes the Wadden Sea, a UNESCO World Heritage site. The plant's location in a coastal area with tidal influences required careful management to prevent nutrient enrichment and protect marine biodiversity. The advanced treatment level helped minimize environmental impact on this ecologically important region.
Environmental context
The plant discharged into the North Sea, specifically into the Wadden Sea area, which is a shallow tidal basin known for its high biodiversity and importance as a migratory stopover for birds. The Wadden Sea is a dynamic coastal ecosystem that relies on good water quality to support seagrass beds, shellfish, and fish populations. Advanced treatment at Dagebull helped reduce nutrient loads, protecting the sensitive marine environment from eutrophication.
