Project overview
The DTSS2 project is the second phase of a nationwide program that completes Singapore’s long-term vision of a recycled water super-highway that further enhances its water security and achieves its ultimate objective of being self sufficient to meet the water demands of its growing population and industries. It comprises of a tunnel conveyance system of approximately 63km of Link Sewers of diameter 0.3-3.0m and 35km of tunnels of diameter 3-6m, adding resiliency to Phase 1 and adopting lessons learned, focusing on energy usage, operational efficiency and minimisation of land-take.
Our role
- Aiding in the initial planning definition phase comprising:
- Feasibility study
- Preliminary design
- Overall programme management for Phase 2 alongside PUB
- Minimising land take whilst freeing up existing land through decommissioning of old parts
Maximising integration with existing infrastructure through cross - connection and linkages
- Minimising personnel and energy usage through use of sustainable energy and technology
- State-of-the-art practices and processes benchmarked against other local and international projects
- Integration of the Tuas WRP with the co-located Integrated Waste
- Management Facility (IWMF) to fully utilise the water/energy nexus, resulting in lower overall operation costs
- The new South Tunnel, Industrial Tunnel and a state-of-the-art Water Reclamation Plant at Tuas to compliment infrastructure in Phase 1
- System resilience
- Synergies between TWRP and IWMF
- Safety incentive scheme
- 6D in building information modeling (BIM)
- Newforma project management information system (PMIS)
- Demonstration plant at Ulu Pandan
- TWRP ground improvement
- Detailed design consultants for link sewers and TWRP
- Five design and build tunnel contracts
- System-wide contracts: roller gates, TIMS, MEICA, IMC, STEMS and ACs
