Overview
Bjergmarken wastewater treatment plant serves Roskilde, Denmark, treating wastewater for approximately 73,253 people. The facility operates under Denmark's implementation of the EU Urban Waste Water Treatment Directive.
Bjergmarken is a wastewater treatment plant located in Roskilde, Region Sjælland, Denmark. Serving a population of approximately 73,253, it is a medium-to-large agglomeration under EU classification. The plant is situated near the coast, within 50 km of the sea, and plays a key role in protecting the local marine environment. As a Danish facility, Bjergmarken operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For plants in sensitive areas, tertiary treatment may be mandated. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating the plant's scale. The treated effluent from Bjergmarken is discharged into the local watershed, which ultimately drains into the Roskilde Fjord and then into the Kattegat sea. This coastal discharge requires careful management to protect the sensitive marine ecosystem, including fish spawning grounds and migratory bird habitats.
Environmental context
The plant's discharge enters the Roskilde Fjord, a shallow estuary connected to the Kattegat and the Baltic Sea. This area supports diverse aquatic life, including fish populations and migratory birds. The fjord is ecologically sensitive due to nutrient loading risks, making advanced treatment important for preventing eutrophication. The plant's coastal proximity underscores the need for effective nutrient removal to protect downstream marine habitats.
Frequently asked questions
Bjergmarken is located in Roskilde, Region Sjælland, Denmark, at Urtevænget 18, Sankt Hans, Roskilde.
The plant serves approximately 73,253 people, classifying it as a medium-to-large agglomeration under EU standards.
Treated effluent is discharged into the local watershed, which flows into Roskilde Fjord and eventually the Kattegat sea.
As a Danish plant, Bjergmarken operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 15,000 population equivalent.
For agglomerations of this size, the EU directive requires at least secondary treatment. In sensitive coastal areas like Roskilde Fjord, tertiary treatment for nutrient removal is often implemented to protect the marine environment.
