Pandan Reservoir (Public Utilities Board, 2012)
Singapore has a land area of
714.3 sq km (Statistics Singapore, 2011), which is about 3.5 times of
Washington D.C. However, unlike other countries, Singapore lacks natural
resources. There is a need to ensure the supply of water for the growing
population.
With the lack of natural
freshwater lake and Singapore’s limited water catchment areas, Singapore
managed to increase the water supply with the help of our neighboring country,
Malaysia. Initially, 80% of Singapore’s water supply came from our neighboring
country (Chowdury, 2009). However, this over reliance acted as a weakness to
this country.
With that in mind, the
Singapore’s government has explored ways to wean off from our neighboring
country, and has partially succeeded with the emergence of technologies such as
desalination and the production of NEWater. Apart from that, to further enhance
and increase the water supply, the Singapore government has increased the
number of water catchment areas.
As of now, Singapore’s water
supply comes from four channels (Public Utilities Board, 2012):
The local catchment areas
consist of rivers and reservoirs. In Singapore, there are a total of 17
reservoirs and 27 rivers (Public Utilities Board, 2012).
Our imported water mainly
comes from Malaysia and the agreement will end in 2061 (Public Utilities Board,2012).
Currently, 40% of the water is imported from Malaysia (Chee, 2010).
NEWater treats used water
with reverse osmosis water, making water to be recyclable. There are altogether
4 plants of NEWater in Singapore – Ulu Panda, Changi, Bedok and Kranji. NEWater
produces 30% of our nation’s water needs (Public Utilities Board, 2012).
Desalinated water comes from
seawater, and it is based on reverse osmosis. Water desalination fulfills 10%
of our nation’s water needs (Public Utilities Board, 2012).
