What are the 4 sources of water in Singapore?
Currently, Singapore has built a robust and diversified supply of water from 4 different sources: water from local catchments, imported water, NEWater (high-grade reclaimed water) and desalinated water.
Which national tap of Singapore will have its capacity reduced as we approach 2061?
This will allow Singapore to be self-sufficient in water should the second water contract with Malaysia not be renewed in 2061. Without any new water contract with Malaysia, the four national water taps will be reduced to three — local catchment water, NEWater and desalinated water.
What is the difference between desalination and NEWater?
As compared to desalination, NEWater is more energy-efficient and cost-efficient to produce because of the lower salt content in treated used water, as opposed to seawater. NEWater is used for both direct non-potable use (DNPU) and indirect potable use (IPU).
Is Singapore facing water shortage?
Water demand in Singapore is currently about 430 million gallons a day (mgd) that is enough to fill 782 Olympic-sized swimming pools, with homes consuming 45% and the non-domestic sector taking up the rest. … By then, NEWater and desalination will meet up to 85% of Singapore’s future water demand.
Will Singapore ever run out of water?
Singapore, a steamy, low-lying island city-state, is the fifth most likely country in the world to face extremely high water stress by 2040, according to the U.S.-based World Resources Institute.
What is Singapore’s main source of water?

Does Singapore have any dams?
The following is a list of reservoirs in Singapore. There are a currently 17 reservoirs which are designated as national water catchment areas and are managed by the Public Utilities Board (PUB) of Singapore.
Does Singapore have a natural lake?
Undoubtedly one of Singapore’s most famous lakes, Jurong Lake is an attraction that draws countless international and local visitors every day. The freshwater lake and reservoir was built primarily to serve as an additional source of water for the country.
Why is desalination so expensive?
One common desalination method, reverse osmosis, is expensive because it requires a great deal of electricity to push water through a filter. It’s also costly to treat the water to kill microbes and to replace the filters. Researchers are hoping that improved membrane materials could make this process cheaper.
