Oslo's “water supply is to a large degree dependent on Maridalsvannet and Oset Water treatment plant, that supply 90 % of the city's drinking water. This means that the water supply is extremely vulnerable to events that can make the source unsuitable or that put the treatment plan out of operation.
The aim of a new water supply is to ensure that Oslo's water supply will provide sufficient quantities of drinking water to the residents, even during failure in vital parts of the water supply system.
Holsfjorden has been selected as the raw water source for the project. Holsfjorden is Tyrifjorden's southern-most part that stretches north toward Svangstrand (Sylling) in Lier municipality. Water will be transferred in a raw water tunnel from Holsfjorden to a new water treatment plant that will be located at Huseby in Oslo West. From Huseby, the drinking water will be transferred to the pipeline network in Oslo with the help of a clean-water tunnel.
