Overview
DASHOLMEN wastewater treatment plant serves Vordingborg, Denmark, with a population equivalent of 9,222. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
DASHOLMEN is a wastewater treatment plant located in Vordingborg, Region Sjælland, Denmark. Serving a population equivalent of 9,222, it is classified as a medium agglomeration under EU regulations. The plant is situated near the coast of southern Zealand, within 50 km of the Baltic Sea. As a Danish facility, DASHOLMEN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 2,000 and 15,000 population equivalent discharging into coastal waters. Denmark implements this directive through national legislation enforced by the Danish Environmental Protection Agency. The plant's designed capacity is 1.00 (likely in thousand m³/day or similar unit), indicating it is sized to handle the local wastewater load. The plant's treated effluent ultimately reaches the Baltic Sea via local watercourses. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it sensitive to nutrient pollution. Discharges from treatment plants in the region contribute to eutrophication concerns, particularly in coastal zones. The plant's location near the coast underscores the importance of effective treatment to protect marine water quality.
Environmental context
DASHOLMEN discharges into local streams that flow into the Baltic Sea near the coast of southern Zealand. The Baltic Sea is a brackish, semi-enclosed sea with limited tidal exchange, making it vulnerable to nutrient enrichment from wastewater discharges. The surrounding watershed supports diverse aquatic life and is an important area for migratory birds. Effective treatment at DASHOLMEN helps reduce the input of nitrogen and phosphorus, which can cause algal blooms and oxygen depletion in coastal waters.
Frequently asked questions
DASHOLMEN is located at 3A Hestehavevej in Vordingborg, Region Sjælland, Denmark. It serves the Vordingborg municipality on the island of Zealand.
DASHOLMEN serves a population equivalent of 9,222, classifying it as a medium-sized agglomeration under EU wastewater treatment regulations.
DASHOLMEN discharges treated effluent into local watercourses that flow into the Baltic Sea. The plant is located within 50 km of the coast, making its discharge subject to coastal water quality standards.
DASHOLMEN operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of its size discharging into coastal waters. Denmark enforces this through national legislation overseen by the Danish Environmental Protection Agency.
For agglomerations between 2,000 and 15,000 population equivalent, the EU directive mandates secondary treatment. In Denmark, this typically involves biological treatment processes such as activated sludge, often with nutrient removal to protect sensitive coastal waters like the Baltic Sea.
