Singapore’s largest desalination plant at Tuaspring has been commissioned. The plant with a capacity of 318,500 cubic metres (cum) can meet 25 per cent of Singapore’s water demand. It was developed by Hyflux Limited on a design-build-own-operate basis; the concession period is 25 years. According to the concession agreement, Public Utilities Board, Singapore’s water agency, will purchase treated water at a fixed price of S$0.45 per cum during the first year of operation. The desalination pretreatment process involves the use of Hyflux’s Kristal ultrafiltration membrane technology. Construction work on the desalination and power plants began in July 2011. Hyflux secured a S$720 million loan from Maybank Singapore, with Maybank Kim Eng Securities Private Limited as the lead arranger. Hyflux also operates Singapore’s first desalination plant – the SingSpring desalination plant whose capacity is 136,000 cum per day.
