Summary
Machine-generated summaryThe SST04 tunnel project is part of protecting Copenhagen, Gentofte and Gladsaxe against flooding caused by cloudburst events. During heavy rainfall, water from the sewer systems of Copenhagen, Gentofte, Gladsaxe and Frederiksberg is directed into the cloudburst tunnel and stored there when capacity allows. Stored water is later pumped through a new emptying line to the Lynetten wastewater treatment plant; if capacity is exceeded, water discharges to the Oresund via an outlet structure at Fiskerihavnen. The works comprise 13 shafts connected by around 3.2 km of segmental tunnel and around 7 km of pipe jacking tunnel, with 15 work sites, 12 tunnel sections, connection structures, sewer connections, an outlet structure, a pumping station with a small above-ground building, and utility relocations.
