Bergen municipality, the Water and Sewage Department, administers water and sewage installations that include over 100 km of tunnels and rock halls. Since 2007 inspections have been carried out for control and securing measures have been implemented in order to take care of safety from collapses and avalanches in many of the installations.
The water and sewage installations in rock consist of a water treatment plant, water basins, cleaning plant for sewage water and transfer tunnels for drinking water and/or sewage water.
In the newer transfer tunnels there are pipelines for both sewage water and drinking water. In some of the old sewage tunnels the sewage water runs on the tunnel floor, in others surface water runs on the tunnel floor and sewage water in a pipe.
There is still a need to check and possibly undertake clearing and securing works in the sewage tunnel from Midtun to Flesland treatment plant and in the sewage tunnel from Indre Aran to Garnes treatment plant. Sewage water runs openly on the floors in both tunnels.
One sewage tunnel from Sælevannet to Knappen treatment plant crosses over the imminent extension of the Ring Road west tunnels at Sandeide. The tunnel shall be inspected and securing measures at the crossing at Sandeide must be completed before March 2012.
In the elevated basin and the long transfer tunnels for drinking water supply with open water surface, periodic cleaning is carried out in accordance at fixed intervals. In connection with the clearing, periodic inspections and the necessary securing works of the rock halls and the tunnels are also carried out.
