SVINNINGE Wastewater Treatment Plant, Svinninge, Denmark

SVINNINGE is a wastewater treatment plant located in Svinninge, Holbæk Municipality, Region Sjælland, Denmark. The plant serves a population of approximately 4,792, classifying it as a small to medium agglomeration under EU classification. Its location near the coast places it in a sensitive area requiring appropriate treatment to protect marine environments. As a Danish plant, SVINNINGE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant has a designed capacity of 1.00 (likely in thousand cubic meters per day or similar unit), indicating it is sized to handle the local wastewater load. The regulatory framework ensures compliance with discharge standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Isefjord or nearby coastal waters of the Kattegat Sea. This area supports diverse marine life and is ecologically sensitive, making proper wastewater treatment essential for maintaining water quality and ecosystem health.

The SVINNINGE plant discharges into the local water system that flows into the Isefjord, a shallow fjord connected to the Kattegat Sea. The Isefjord is an ecologically important area supporting fish, birds, and aquatic vegetation. As a coastal region, it is sensitive to nutrient pollution, which can cause eutrophication and algal blooms. The plant's treatment level is critical for protecting this downstream environment.
