Design, supply, supervision of installation, testing and commissioning of roller gates for the deep tunnel sewerage system phase 2 project.

Singapore’s DTSS Phase 2 extends the existing deep tunnel system to collect used water from the western and southern parts of Singapore. When completed, it will have a conveyance system that is made up of 60 km of link sewers and 40 km of deep tunnels.

The new feature in the DTSS Phase 2 tunnel is the ability to isolate sections of the tunnel using gates.
