Leighton Asia is delivering Contract T-09 of the Deep Tunnel Sewerage System Phase 2 Project, which includes design and construction of approximately 7.9km of used water tunnels, each with an internal diameter of six metres, as well as shafts, hydraulic structures and other facilities associated with the used water sewerage conveyance system. Tunnel excavation will be carried out by tunnel boring machines.

The Deep Tunnel Sewerage System utilises large, deep tunnels to convey used water to centralised water reclamation plants for further treatment. With Phase 1 of the project completed in 2008, Phase 2 will be delivered via a number of works packages to eventually complete 40km of deep tunnels and 60km of link sewers, along with associated hydraulic structures and air management facilities.
