Overview
Solumstrand avlopsanlegg is a wastewater treatment plant serving approximately 97,443 people in Drammen, Norway. It operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Solumstrand avlopsanlegg is a wastewater treatment facility located in Drammen, Buskerud, Norway, serving a population of around 97,443. The plant is situated along the Drammensfjord, a fjord that connects to the Oslofjord and ultimately the Skagerrak Sea. As a medium-to-large agglomeration, the plant is subject to Norway's national regulations which align with the EU Urban Waste Water Treatment Directive (91/271/EEC). Under the EU UWWTD, agglomerations with a population equivalent (PE) between 10,000 and 150,000 are required to have secondary treatment as a minimum. For sensitive areas, such as fjords and coastal waters, more stringent treatment may be required to prevent eutrophication. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the wastewater from the served population. The treated effluent from Solumstrand avlopsanlegg is discharged into the Drammensfjord, which is part of the Oslofjord watershed. The Oslofjord is an ecologically important marine environment that supports diverse aquatic life, including fish populations and marine habitats. Proper treatment is essential to protect water quality in this sensitive coastal ecosystem, which is also used for recreation and fishing.
Environmental context
The plant discharges into the Drammensfjord, a fjord that flows into the Oslofjord and then the Skagerrak Sea. This coastal environment is sensitive to nutrient loading, which can cause algal blooms and oxygen depletion. The Oslofjord supports diverse marine life, including cod, herring, and various shellfish, and is an important area for both commercial and recreational fishing. Effective wastewater treatment is critical to maintaining the ecological health of this fjord system.
Frequently asked questions
Solumstrand avlopsanlegg is located in Drammen, Buskerud, Norway, near the Drammensfjord.
The plant serves approximately 97,443 people, classifying it as a medium-to-large agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into the Drammensfjord, which flows into the Oslofjord and then the Skagerrak Sea.
As a Norwegian plant, it operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size.
For agglomerations between 10,000 and 150,000 PE, the EU UWWTD requires secondary treatment. In sensitive coastal areas like the Oslofjord, tertiary treatment may be needed to reduce nutrients and protect the marine environment.
