Tunnel and waste water treatment plants
A 14 kilometer long tunnel will be built to lead the wastewater from Bromma to Sickla. Once the tunnel has been completed, Bromma wastewater treatment plant will be decommissioned and the wastewater from Västerort can be treated in Henriksdal's wastewater treatment plant, which will be optimized with modern membrane technology. We begin to build the tunnel no earlier than summer 2019.
