PUB awards SG$449 million Domestic Liquids Modules contract for Tuas Water Reclamation Plant

Singapore, 30 July 2020 — The Public Utilities Board (PUB), Singapore’s national water agency, has appointed Sinohydro Corporation Ltd (Singapore Branch) to construct the civil and structural components of Domestic Liquids Modules (DLMs) for the Tuas Water Reclamation Plant (WRP) starting in August 2020, with a contract valued at SG$449 million.

This award is the fourth major Tuas WRP construction contract. The first was for site development works in January 2019; the second for the building of Tuas WRP’s Influent Pumping Stations in July 2019; and the third was for the plant’s biosolids treatment facility in March 2020.

Another seven construction tenders worth SG$1billion will be called for before the end of 2021, including the plant’s Industrial Liquid Modules (ILMs) that will treat industrial used water.

Tuas WRP, a key component of PUB’s Deep Tunnel Sewerage System (DTSS) Phase 2 project, will be equipped to receive both domestic and industrial used water streams from two separate deep tunnels for treatment. The plant’s two DLMs will house the various facilities—including biosorption tanks and membrane bioreactor systems—required to treat domestic used water; and will have an initial treatment capacity of 800,000 metre cubic per day.

The plant will be co-located with the National Environment Agency’s (NEA) Integrated Waste Management Facility (IWMF) to collectively form Tuas Nexus, which integrates solid waste and used water treatment processes to harness various synergies that will improve overall plant performance and optimise land use.

The DTSS Phase 2 is a SG$6.5 billion infrastructure project that will enhance Singapore’s water sustainability by boosting PUB’s capability to reclaim and recycle water in an endless cycle. Upon completion in 2025, DTSS Phase 2 will convey used water from the western part of Singapore to Tuas WRP for treatment. DTSS Phase 1, which covers eastern Singapore and channels used water to Changi WRP, was completed in 2008.
