Overview
Frejlev wastewater treatment plant serves approximately 2,500 residents in Guldborgsund Municipality, Region Sjælland, Denmark. The facility operates under Denmark's implementation of the EU Urban Waste Water Treatment Directive.
Frejlev wastewater treatment plant is located in the town of Frejlev, within Guldborgsund Municipality in Region Sjælland, Denmark. The plant serves a population of approximately 2,500 people, classifying it as a small agglomeration under EU regulations. As a Danish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges to inland waters. For small agglomerations like Frejlev, secondary treatment or equivalent is typically mandated to protect water quality. The treated effluent from Frejlev is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Guldborgsund strait. This coastal discharge area supports diverse marine life and is part of a sensitive ecosystem that benefits from effective wastewater treatment to prevent nutrient enrichment.
Environmental context
The plant's discharge enters the local water system that flows through Guldborgsund and into the Baltic Sea, a semi-enclosed sea with limited water exchange. The Baltic Sea is sensitive to nutrient pollution, which can cause algal blooms and oxygen depletion. Effective treatment at Frejlev helps reduce the input of nitrogen and phosphorus, supporting the ecological health of this important marine environment.
