Sembcorp bags $300m contract to build biosolid treatment facility in Singapore

Sembcorp Design and Construction, a wholly-owned subsidiary of property group Chip Eng Seng, has been awarded a contract, worth SGD433m ($300.8m) to build biosolid treatment facility for the Tuas Water Reclamation Plant (WRP).

Under the contract awarded by Singapore’s national water agency Public Utilities Board (PUB), Sembcorp will be responsible for the design and construction of the Tuas WRP’s biosolids building, digesters and greasy waste receiving facility.

The company plans to commence work on the facilities in April 2020 and complete in 2025. The Tuas WRP forms part of Phase 2 of the Deep Tunnel Sewerage System project.

The facilities are claimed to form the key interface between Tuas WRP and the National Environment Agency’s (NEA) Integrated Waste Management Facility (IWMF). The Tuas WRP and IWMF are collectively known as Tuas Nexus.

PUB  DTSS 2 director Yong Wei Hin said: “This is a key contract that will build components critical to realising the synergies between Tuas WRP and IWMF, with PUB and NEA working together closely to make Tuas Nexus a reality. Once completed, Tuas Nexus will set the bar for addressing long-term resource sustainability and climate change.”

Scheduled for completion in 2025, the PUB’s DTSS Phase 2 project involves the construction of a 100km network of deep tunnels and link sewers.

The project will channel used water from the western half of Singapore for treatment at Tuas WRP, which will house the membrane bioreactor facility. Tuas WRP will have initial treatment of capacity of 800,000m³ per day.

Last year, PUB selected a joint venture to build Tuas WRP’s Influent Pumping Stations, which will be used to pump used water from the underground sewerage tunnels to the plant for treatment.
Over the next two years, PUB plans to launch 14 construction tenders for Tuas WRP.
