The works will be carried out in two packages – one for the northern tunnel and one for the southern tunnel and Sjölunda treatment plant.
The 10km northern tunnel will have an internal diameter of 3m and connect Källby in Lund to the treatment plant. The tunnel will be 25-30m below ground level and have a storage capacity of 80,000m3.
There will be four 15-40m-deep shafts along the tunnel. The entry shaft will have a 20m diameter and the other three will have diameters of 9-13m.
The 5.5km southern tunnel will stretch from Turbinen in Malmö to the Sjölunda treatment plant. It will have a 5m internal diameter and storage capacity of 100,000m3. It will connect to two micro tunnels with internal diameters of 2m.
There will be 11 shafts along the tunnel route; the one closest to Sjölunda will have a diameter of 45m to make room for the new pumping station, while the others will be 4-15m in diameter.
“The plan is to award the contracts at the end of 2027, in order to be able to start the construction work in 2028 and complete it around 2032,” said Lars Landén, main project manager for the project.
Maxima, which will convey waste water from several municipalities to the rebuilt Sjölunda treatment plant, is due to be operational by 2035.
The deadline for requests to participate is August 31, 2026. For more information, click here.
