Tuaspring desalination plant, the wholly-owned subsidiary of Hyflux Singapore, is the second and largest desalination project in Singapore. The plant is expected to commence operations in 2013.

The Design, Build, Own and Operate (DBOO) plant, which total project costs is estimated to be S$ 1.05 billion, will also come with its own on-site 411MW Combined Cycle Gas Turbine (CCGT) power plant generating electricity meant for own consumption.

The plant would feature the world’s second largest installation of ultrafiltration membranes in the pre-treatment process of a seawater reverse osmosis or SWRO desalination plant. Upon completion, the desalination plant will provide another 318,500m3 of desalinated water per day to Singapore’s water supply. Desalinated water, which now provides 25% of Singapore’s water, is one of the four National Taps, along with local catchment water, imported water and NEWater. This will definitely improve the drought resilience capability of Singapore’s water supply and ensure reliability for Singapore’s water users.
