Singapore's Current Water Supplies (Desalinated Water)

The SingSpring desalination plant was PUB’s first public-private partnership project. This plant can produce 30 million gallons or 136, 000 cubic meters of water a day and is one of the region’s largest seawater reverse-osmosis plants.
Desalinated water is the result of PUB's continued investments in water technologies and research. Recent advancements in technology and cheaper membrane prices have made desalinated water another viable source of water supply for Singapore.
At the SingSpring plant, sea water goes through a pre-treatment process where suspended particles are removed. In the second stage, the water undergoes reverse osmosis. The water produced is very pure and is remineralised in the third stage. After treatment, desalinated water is blended with treated water before it is supplied to homes and industries in the western part of Singapore.
