GROW WITH THE FLOW
 
COLLECTING EVERY DROP OF RAIN
 
 
 
As Singapore is an island, desalinating water is a natural step. After years of monitoring desalination technologies, especially the successful application of desalination technologies with lower energy usage, Singapore finally turned on its fourth National Tap in September 2005, with the opening of the SingSpring Desalination Plant in Tuas.

The SingSpring plant is PUB's first public-private partnership (PPP) project. This plant can produce 30 mgd (136,000 m3/day) of desalinated water, and is one of the region's largest seawater reverse osmosis plants.

Like NEWater, desalinated water is independent of rainfall and can be used to supplement water from local reservoirs in an extended dry spell, like the one experienced in February 2010.

We plan to increase desalination capacity to further enhance the drought resilience of our water supply, and ensure reliability for Singapore's water users.

However, desalination is currently the most energy intensive water supply source and therefore the most expensive in terms of production costs.

Much research and development work is being carried out in Singapore and around the world in search of more cost-efficient ways of producing desalinated water.
 
Water for All
The Singspring Desalination Plant uses reverse osmosis membrane technology to produce desalinated water.
