Singapore Completes S$120M Tengah Reservoir for 42,000 Homes, June 17

Singapore’s national water agency PUB completed the S$120 million Tengah Service Reservoir in November 2025, a decade-long project now set to serve 42,000 households and the Tengah industrial precinct. Deputy Prime Minister Gan Kim Yong announced the milestone on June 16 at Singapore International Water Week, highlighting the project as proof of long-term infrastructure planning. The reservoir holds the equivalent of 22 Olympic-sized pools of treated drinking water.

A Decade of Planning, Three Years of Construction

Planning for the Tengah Service Reservoir began in 2016, and construction took more than three years to complete. The facility comprises two five-storey high tanks with brown aluminium fins designed to blend with Tengah’s forest landscape. Built on the highest point in the area, the reservoir uses gravity to maintain stable water pressure across the network without additional pumping, reducing operational costs.

Why Singapore Needs More Water Storage

Tengah is expected to house 42,000 households plus businesses in the upcoming Tengah industrial precinct, part of the Jurong Innovation District. Water-intensive sectors like semiconductors and data centres will require about two-thirds of Singapore’s future water demand by 2065. The service reservoir stores treated drinking water from PUB’s treatment plants before distribution to households and businesses, acting as a buffer during peak usage or supply disruptions.

S$85 Million Pledged for Water Research

Beyond the reservoir, Singapore will invest nearly S$100 million in water research and development. Under the Research, Innovation and Enterprise 2030 plan, S$85 million goes to PUB for advancing desalination, contaminant management, and used water treatment. A new research facility launching in 2027 will harness used water to generate more energy than it consumes, supporting both economic growth and environmental sustainability.

Climate Threats Drive Long-Term Planning

DPM Gan warned that climate change will bring more extreme dry and wet periods. Nearly a third of Singapore faces coastal flooding risk if sea levels rise unchecked. The Tengah reservoir demonstrates how planning and investment build resilience ahead of demand, integrating water planning with urban and economic development to ensure future generations inherit reliable systems.

Final Thoughts

Singapore’s S$120 million Tengah reservoir and S$85 million water research commitment show the government prioritizes long-term infrastructure over short-term gains. For investors in Singapore’s water and utilities sector, this signals sustained public spending on resilience and innovation.
