Completely unique solutions
Nothing about Kalvebod Brygge Cloudburst Tunnel is standard. Everything is custom-made and unique – which is exactly why HOFOR and Frederiksberg Utility have chosen to test the solutions at DHI.
The cloudburst tunnel is expected to be needed around once every five years during particularly powerful cloudbursts. In that event, the cloudburst tunnel will prevent floods in Copenhagen, which would otherwise cost billions in damages. The solution consequently has to work perfectly.
The call for tenders is expected in August 2020. This means, that the construction will commence around August 2021, and finally the tunnel is expected to be commissioned in 2025.
