BEKKELAGET WATER TREATMENT PLANT: OSLO GROWS AND THE PLANT IS EXPANDED

Oslo is Europe's fastest growing city. In order to maintain the quality of the water in the Oslo fjord, it is necessary to expand water treatment capacity. The Agency for Water and Sewerage Works In Oslo Municipality has commissioned Sweco to carry out the work – while the existing plant remains fully operational.

Assignment and solution

The water treatment plant is Norway's second largest
In 2001 the capacity of the plant was designed for 270,000 people and will now be further increased to manage sewerage and waste water from 490,000 people. The new water treatment plant must also comply with new environmental requirements. Sweco's mains water and sewerage experts will provide design within the disciplines of machine processing, automation, acoustics and regulation in close collaboration with Cowi, who are responsible for the associated specialist disciplines.

The plant shall contain the same functions as the current plant, with pre-treatment, biological purification stages in active sludge, post sedimentation and final polishing in sand filters. The sludge treatment capacity will be increased.

We use the newest technology
Sweco has placed emphasis on utilising state-of-the-art technology in the machine-technical components. In the operational control plant we have facilitated reliable and stable operation. Good acoustic solutions also improve working conditions for employees.
