Singapore – PUB, Singapore’s National Water Agency, has appointed a joint venture between Binnies Singapore and AECOM to deliver professional engineering services for the Phase 3 expansion of the Changi Water Reclamation Plant (WRP), one of the largest used water treatment facilities in the world.
The third phase of expansion will increase the plant’s treatment capacity by up to 96 million gallons per day, strengthening Singapore’s long-term water sustainability and resilience. Changi WRP is also a cornerstone of the Deep Tunnel Sewerage System (DTSS) and plays a vital role in PUB’s used water management strategy.
Under the new contract, the Binnies–AECOM joint venture will provide preliminary design, cost-benefit analysis, environmental studies, detailed design, and construction supervision for the expansion. Long-term planning for future capacity growth will also be undertaken.
“The project aims to boost the capacity and operational efficiency of the facility through advanced used water treatment technologies,” said William Yong, Managing Director of Binnies Singapore. “A future-ready masterplan will ensure the sustainability and resilience of Changi WRP.”
Beverley Stinson, Chief Executive of AECOM’s Global Water Business, highlighted that the project will leverage global expertise in water reuse technologies:
“This expansion reinforces Singapore’s position as a global leader in advanced used water treatment.”
With over a decade of experience supporting PUB, AECOM’s Asia CEO Ian Chung noted that the company’s systemwide knowledge of Singapore’s water infrastructure will be key to successful delivery. RSK Board Director Gary Young added that the project contributes to Singapore’s “Water Story” by future-proofing critical water infrastructure.
Once completed, the Phase 3 expansion will enhance Singapore’s water security and provide a more sustainable supply to meet future demand.
