Technical requirements: Vann- og avløpsetaten (VAV) [the Agency for Water and Sewage] handles the sewage water and supplies Oslo's population with drinking water. This is financed through water and sewage fees. The Agency for Water and Sewage is responsible for the development and operation of the water and sewer systems in Oslo. The Agency for Water and Sewage is responsible for the operation, maintenance and renewal of the city's treatment plants, as well as the pipeline network and pumping stations for both drinking water and sewage water. Other primary assignments are the management of water source areas, monitoring the waterways in the city, guidance and information to customers, subscribers and society in general.

One water source and one water treatment plant currently supply about 90 percent of the population in Oslo with drinking water. This makes the water supply extremely vulnerable.
Therefore, Oslo municipality is now building a reserve water supply and we are planning new water supply tunnels (trunk network). The work is organised in two projects:
• the project Ny vannforsyning Oslo will carry water from the new water source, Holsfjorden, to the new water treatment plant at Huseby. Clean water is carried by tunnel to Sagene. A development plan for this project was adopted in November 2019 and construction start is planned for the third quarter of 2020.
• Stamnettprosjektet will carry clean water by tunnel from Sagene to Disen and further to Trosterud and from the existing water treatment plant at Oset (Kjelsås) to Disen. The project is in the review phase, where we collect input to the zoning plan from public bodies and other interested parties. The tunnels will be operated drilled both conventionally and through the use of TBM (tunnel boring machine). Construction start is planned for the first quarter of 2022.
This notice concerns landfill of clean masses from Stamnettprosjektet. You can read more about Stamnettprosjektet on this page: https://www.oslo.kommune.no/slik-bygger-vi-oslo/ny-vannforsyning-stamnett/#gref. More information about the project Ny vannforsyning Oslo can be found here:https://www.oslo.kommune.no/slik-bygger-vi-oslo/ny-vannforsyning-oslo/.
Mass landfills when the construction works begin. Therefore, contracts must be signed with landfill(s) with the necessary permits in the vicinity of the construction area at Stubberud. The landfill must be located within 1.5 t/r from the rigging area at Stubberud. The distance boundary is set in order to minimise environmental drawbacks of masses transport.
There are currently many uncertainties concerning the masses, amongst other things, in regard to quantity, dates for availability and kind, in addition there is uncertainty connected to public permits. VAV wants already now, to ensure the progress of the project and start the process of investigating the possibility of mass landfills in the Oslo region.
In addition to being able to receive clean masses from Stamnettprosjektet, any agreement (s) will also include an option to the treatment of TBM masses from the project New water supply (Norwegian: NVO) at Oslo's construction area at Huseby. The total requirement for disposal at masses from Huseby amounts to approx. 500 000 tonne of clean masses.
For practical and economic reasons, the minimum capacity requirement at the mass landfill is set at: 400 000 tfm
Basically, VAV wants to make contact with actors who will receive clean masses free of charge, but also actors who demand remuneration are requested to register their interest.
All interested parties should take contact as soon as possible and at the latest before the deadline of 15 October 2020. We can be contacted by message in KGV or by email to asbjorn.karlsrud@vav.oslo.kommune.no
