Stockholm Vatten AB (SV) is planning to undertake the upgrade of the city's Waste Water Treatment system in Stockholm, Sweden.

The project involves the upgrade of Henriksdalsringen Waste Water Treatment plant (WWTP) and the construction of a 15km sewage tunnel using drill and blast method from Bromma sewage treatment plant to Henriksdalsringen WWTP that will be 30-90m below ground level, a new pump station, new coarse screening and primary sedimentation basins, the installation of related machinery and safety equipment, the demolition of Bromma sewage treatment plant, and the laying of pipelines.

The sewage tunnel will be dug rather than drilled, both because of the soil conditions and that it will become cheaper.

Tyrens has been appointed as an environmental consultant, AF Group to deliver electrical solutions including telecommunications and automation systems.
