Kongsted Wastewater Treatment Plant, Faxe, Denmark

Kongsted wastewater treatment plant is located in Faxe, within Region Sjælland, Denmark. It serves a population of around 3,587 people, making it a small-scale municipal facility. The plant is situated near the coast, within 50 km of the Baltic Sea. As a Danish treatment plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 volume units, indicating the plant's scale. Danish plants typically employ mechanical-biological treatment to meet national and EU standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea. This coastal region supports diverse aquatic life and is an important ecological area. The plant plays a key role in protecting local water quality and the downstream marine environment.

Kongsted WWTP discharges into the local watershed that flows into the Baltic Sea, a semi-enclosed sea with limited water exchange. The Baltic Sea is sensitive to nutrient pollution, which can cause eutrophication and algal blooms. The plant's treatment helps reduce nutrient loads, supporting the ecological health of coastal waters and habitats for fish and migratory birds.
