Singapore’s 5th desalination plant opens on Jurong Island to boost water security

The plant can produce up to 30 million gallons of potable water.

The Jurong Island Desalination Plant (JIDP), has opened to boost Singapore’s water supply, the PUB said.

The plant can produce up to 30 million gallons of potable water and is approximately 5% more energy efficient compared to conventional desalination plants because of its close location to Tuas. 

It will be operated by TP-STM Water Resources Pte Ltd – the Joint Venture company formed by the Tuas Power-ST Engineering consortium – for 25-years. 

With over 3.7 hectares, JIDP receives seawater from Tuas Power’s Tembusu Multi-Utilities Complex for processing into potable water.

PUB Chief Executive Ng Joo Hee said even as seawater desalination is expensive on energy costs, it is still an essential potable water source for Singapore.

“The efficiencies that come from constructing JIDP, our fifth and newest desalination plant, next to Tuas Power’s existing TMUC make the energy-take for desalination that much more palatable. JIDP further diversifies our water production portfolio and its coming into operation enhances Singapore’s water security,” he added.
