SingSpring Desalination Plant
In September 2005, Singapore turned on its fourth National Tap - desalinated water, with the opening of the SingSpring Desalination Plant in Tuas. It was PUB’s first public-private partnership (PPP) project. SingSpring Pte Ltd was appointed to design, build, own and operate the plant and supply water to PUB. One of the region’s largest seawater reverse-osmosis plants, this plant can produce 30 million gallons of water (130,000 m3) a day.

At the SingSpring desalination plant, sea water first goes through a pre-treatment process where suspended particles are removed before reverse osmosis (RO), using the same technology for the production of NEWater. The water produced is very pure and is then remineralised. After treatment, desalinated water is blended with treated water before it is supplied to homes and industries in the western part of Singapore.
Tuaspring Desalination Plant
Tuaspring Desalination Plant is the second and larger desalination plant with a capacity of 70 million or 318,500 m3 of desalinated water per day.

There are currently two desalination plants in Singapore with a combined capacity of 100 mgd and this can meet up to 25% of Singapore’s current water demand. The third desalination plant is expected to be completed in Tuas by 2017, and the fourth in Marina East by 2020. Desalinated water is expected to meet up to 30% of Singapore’s future water needs by 2060.
