Hankintapäätös
A new elevated basin will be established at Tryvannstårnet, a pipeline route between the new basin and the existing pipeline installations and new pipeline installations in Voksenkollveien. By establishing a new elevated basin at Tryvannstårnet the current pressure zone 500 will change to pressure zone 530. A new pipeline route in Voksenkollveien will contribute to providing a two-way water supply to the area Holmenkollen – Voksenåsen. Establishment of a new elevated basin and new pipeline route will make the water supply in the area Holmenkollen - Voksenåsen less vulnerable and will contribute to delivering enough water with enough pressure to the area Holmenkollen – Voksenåsen.
