DAMHUSAEN Wastewater Treatment Plant, Kastrup, Denmark

DAMHUSAEN is a major wastewater treatment plant located in Kastrup, Tårnby Kommune, within the Capital Region of Denmark. Serving a population equivalent of around 280,847, it is a large-scale facility critical to the region's sanitation infrastructure. As a Danish plant, DAMHUSAEN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 15,000 population equivalent and tertiary treatment in sensitive areas. Given its size, the plant is expected to meet advanced treatment standards to protect the receiving environment. The plant's treated effluent discharges into local water bodies that ultimately drain into the Øresund, the strait between Denmark and Sweden connecting the Baltic Sea to the North Sea. This coastal discharge requires careful management to safeguard marine ecosystems and comply with stringent Danish and EU environmental regulations.

DAMHUSAEN discharges into the Øresund, a critical marine corridor connecting the Baltic Sea to the North Sea. The Øresund supports diverse aquatic life, including fish, seabirds, and marine mammals, and is an important migratory route. Nutrient and pollutant loads from the plant must be minimized to prevent eutrophication and protect this ecologically sensitive coastal environment.
