FREDERIKSSUND Wastewater Treatment Plant, Frederikssund, Denmark

FREDERIKSSUND is a wastewater treatment plant located in Frederikssund, Denmark, within Region Hovedstaden. It serves a population of approximately 27,768, classifying it as a medium-sized agglomeration under Danish and EU regulations. The plant is situated near the coast, reflecting the region's coastal geography. As a Danish facility, FREDERIKSSUND operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale. Compliance with EU standards ensures appropriate treatment for the receiving environment. The plant's treated effluent ultimately reaches the Kattegat or nearby coastal waters, contributing to the marine ecosystem of the Baltic Sea region. The surrounding area supports diverse aquatic life, and the plant plays a key role in protecting local water quality and downstream habitats.

FREDERIKSSUND discharges into the local watershed that drains toward the Kattegat, a sea area connecting the Baltic Sea to the North Sea. This coastal region supports important marine biodiversity, including fish spawning grounds and migratory bird habitats. The plant's operations help maintain water quality in the sensitive coastal environment, reducing nutrient loads that could otherwise contribute to eutrophication in the Baltic Sea.
