Burg Wastewater Treatment Plant, Fehmarn | Schleswig-Holstein, Germany

Burg wastewater treatment plant is located in Burg auf Fehmarn, a town on the island of Fehmarn in the Baltic Sea. The plant serves a population of about 15,569 people and is part of the municipal infrastructure of Fehmarn, which lies in the state of Schleswig-Holstein, Germany. The facility operates under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. As a German plant serving a medium-sized agglomeration, Burg is expected to meet secondary treatment standards under the EU directive. The plant's designed capacity is 1.00 million cubic meters per year, indicating it is sized to handle the local wastewater load. Typical German plants of this scale employ biological treatment with nutrient removal to protect sensitive coastal waters. The treated effluent from Burg is discharged into the Baltic Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant plays a crucial role in protecting the coastal ecosystem of Fehmarn Island and the broader Baltic Sea, which supports diverse marine life and is an important area for tourism and fisheries.

The Burg plant discharges treated wastewater into the Baltic Sea near Fehmarn Island. The Baltic Sea is a brackish water body with limited circulation, making it vulnerable to eutrophication from nutrient inputs. The plant's location within 50 km of the coast means its discharge can affect local marine habitats, including seagrass beds and fish spawning grounds. Effective treatment helps maintain water quality for the island's tourism and fishing industries.
