Tenders open for Singapore’s DTSS Phase 2 and IWMF

Tenders open for Singapore’s DTSS Phase 2 and IWMF

July 19, 2016 , 0

Tenders have been requested for part of the S$9.5 billion Deep Tunnel Sewerage System (DTSS) Phase 2 and the Integrated Waste Management Facility (IWMF) in Singapore.

The Public Utilities Board (PUB) and National Environment Agency of Singapore (NEA) are seeking submissions for used water and solid waste management solutions on the project.

Planned works on DTSS Phase 2 are estimated to cost US$4.82 billion and included enhanced deep tunnels with advanced sensing and maintenance features, associated link sewers, Tuas Water Reclamation Plant (TWRP) and an integrated NEWater Facility.

The IWMF is expected to cost US$2.23 billio) to construct and will be able to process waste streams including incinerable waste, household recyclables, source segregated-food waste, dewatered sludge from the TWRP and will have an incineration capacity of 5,800 tonne per day.

When it is completed the TWRP will have a treatment capacity of 800,000 cubic metre per day and will be the largest membrane bioreactor facility in the world.

PUB DTSS Phase 2 Director Mr Yong Wei Hin said “As one of the world’s most anticipated water infrastructure projects, DTSS Phase 2 continues to harness advanced technologies to enhance Singapore’s used water management system and ensure its water sustainability for generations to come.

“The co-location of TWRP and IWMF is also the first project of its kind in the world to be planned from ground-up, and is designed to bring about a multitude of synergies harnessing the Water-Energy-Waste Nexus while optimising Singapore’s land-use.”

The project is currently in the detailed design stage, but tenders will be requested later this year for works that included detailed engineering services and detailed design for the TWRP and link sewers, design and construction of deep tunnel sewers, associated shafts and manholes.

NEA IWMF Project Director Mr Joseph Boey said “The co-location of the TWRP and IWMF marks a new chapter in the way used water and solid waste are managed in land-scarce Singapore.

“Leveraging the use of advanced technologies and project innovations, the two facilities will be able to maximise energy and resource recovery efficiencies while minimising their environmental and land footprint.

“The IWMF plays an integral part in meeting Singapore’s future waste management needs, and ensuring long term environmental sustainability.”
