Koh Brothers Eco Engineering nabs $668.2m contract from PUB

It will construct influent pumping stations for the Deep Tunnel Sewerage System Phase 2 project.

Catalist-listed Koh Brothers Eco Engineering, through its subsidiary Koh Brothers Building & Civil Engineering (KBCE), has clinched a $668.2m contract from the Public Utilities Board (PUB), an announcement revealed.

Under the contract, the firm will construct the influent pumping stations (IPS) at Tuas Water Reclamation Plant (TWRP), which will lift Koh Brothers Eco Engineering’s order book beyond $1b from $632.3m as at March 2019.

The TWRP will be developed as part of the Deep Tunnel Sewerage System (DTSS) Phase 2 project. The construction of the influent pumping stations will be carried out in collaboration with KBCE’s joint venture partner, China Harbour (Singapore) Engineering Company. Koh Brothers Eco has an effective stake of 60% in the joint venture company (JV Co).

According to Koh Brothers Eco’s CEO Paul Shin, the JV Co will be responsible for the construction of the IPS and substations A & B required under Contract 2A of the DTSS Phase 2 project. “In particular, the IPS consisting of five shafts up to 80 m deep will convey used water from the deep tunnels to the treatment units within TWRP,” he explained.

The contract consists of two parts – construction works that will commence later in July, as well as operation and maintenance services. Construction is expected to take 75 months to complete, followed by 53 months of operation and maintenance services.

The DTSS, an underground superhighway that conveys used water via gravity to centralised water reclamation plants located in coastal areas, is said to be a cost-efficient and sustainable solution to meet Singapore’s long-term needs for used water collection, treatment, reclamation and disposal. The first phase of DTSS, which serves the eastern part of Singapore, was completed in 2008.

DTSS Phase 2, which is on track to be completed by 2025, will serve the western half of Singapore and feature a 100-km network of deep tunnels and link sewers that will channel used water to TWRP.
