Design and construction of sewer tunnels for the deep tunnel sewerage system phase 2 project – contract t-07
A superhighway for used water management, the DTSS is a cost-effective and sustainable solution to support Singapore’s continued growth and meet its long-term needs for used water collection, treatment, reclamation and disposal. The deep tunnels collect and convey used water entirely by gravity to centralised Water Reclamation Plants located at coastal areas. Phase 2 extends the deep tunnel to serve the western part of Singapore.
