Singapore’s newest piece of critical water infrastructure is set to come online this year with the completion of the Tengah Service Reservoir, a S$120 million development designed to support the town’s future growth. Positioned at the highest point of Tengah and planned more than a decade ago, the reservoir reflects the nation’s long-term approach to infrastructure planning, ensuring water resilience is built ahead of demand as new residential neighbourhoods and industrial developments continue to take shape across the western region.
Designed with Tengah’s distinctive forest-town identity in mind, the facility features two striking five-storey-high tanks clad with dark brown aluminium fins that blend into the surrounding landscape. Together, the reservoirs can store the equivalent of approximately 22 Olympic-sized swimming pools of treated drinking water, providing a vital buffer against fluctuations in daily consumption and ensuring a reliable supply during periods of peak demand. Serving an estimated 42,000 households as well as the future Tengah industrial precinct within the Jurong Innovation District, the facility has been strategically located on elevated ground, allowing water to flow naturally to surrounding estates through gravity without the need for additional pumping.
Beyond its scale, the project also highlights advancements in construction and sustainability. The reservoir is the first of its kind in Singapore to utilise slipform construction technology, enabling the creation of seamless circular tank walls that reduce the risk of water leakage. Environmental considerations were also incorporated throughout the development process, with measures implemented to minimise disruption to the surrounding forest habitat. Equipped with real-time monitoring systems and advanced water quality controls, the Tengah Service Reservoir represents the next generation of resilient urban infrastructure, supporting Singapore’s continued commitment to sustainable growth and water security for future generations.
