Overview
Holen renseanlegg is a municipal wastewater treatment plant serving Bergen, Norway. It treats wastewater from approximately 71,000 people and operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Holen renseanlegg is a wastewater treatment plant located in the Laksevåg district of Bergen, Norway. It serves a population of approximately 71,048 people, making it a medium-to-large agglomeration under Norwegian and EU classification. The plant is situated in the coastal city of Bergen, which is known for its fjord landscape and maritime climate. As a Norwegian facility, Holen renseanlegg operates under the national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with more advanced treatment if the receiving waters are sensitive. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a substantial infrastructure to handle the city's wastewater. The treated effluent from Holen renseanlegg is discharged into the coastal waters of the North Sea via the Bergen fjord system. This area supports diverse marine life and is important for local fisheries and recreation. The plant plays a critical role in protecting the fjord ecosystem from nutrient pollution and pathogens, helping to maintain water quality in a region known for its pristine natural environment.
Environmental context
Holen renseanlegg discharges treated wastewater into the coastal waters of the North Sea via the Bergen fjord system. The fjords are deep, narrow inlets with limited water exchange, making them sensitive to nutrient loading and pollution. The receiving waters support diverse marine life, including fish, crustaceans, and seabirds, and are important for local fisheries and tourism. Proper treatment is essential to prevent eutrophication and maintain the ecological health of this unique coastal environment.
Frequently asked questions
Holen renseanlegg is located in the Laksevåg district of Bergen, Norway, at Johan Berentsens vei, Nygård. It serves the city of Bergen and surrounding areas.
The plant serves approximately 71,048 people, classifying it as a medium-to-large agglomeration under EU and Norwegian wastewater regulations.
The treated effluent is discharged into the coastal waters of the North Sea via the Bergen fjord system. The fjords are sensitive environments that require effective treatment to prevent pollution.
As a Norwegian plant, it operates under national regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations over 10,000 people, secondary treatment is required, with tertiary treatment in sensitive areas.
Plants of this scale in Norway typically provide at least secondary biological treatment. Many also include nutrient removal (nitrogen and phosphorus) to protect sensitive fjord and coastal waters from eutrophication.
