The 4 National in Taps Singapore

The 4 National in Taps Singapore
Desalinated
In September 2005, Singapore turned on its
fourth National Tap, desalinated water, with the
opening of the SingSpring Desalination Plant in
Tuas .

Imported Water
Singapore has been importing water from Johor, Malaysia,
under two bilateral agreements. The first agreement
expired in August 2011 and second agreement will expire
in 2061.
The Catchment Water
Singapore's Usage Of Water
As a small island that doesn't have natural aquifers
and lakes and with little land to collect rainwater,
Singapore needs to maximise whatever it can
harvest.
Why?
As a small island that doesn't have natural
aquifers and lakes and with little land to collect
rainwater, Singapore needs to maximise
whatever it can harvest.
Currently, Singapore uses two separate
systems to collect rainwater and used water.
Rainwater is collected through a
comprehensive network of drains, canals, rivers
and stormwater collection ponds before it is
channelled to Singapore's 17 reservoirs for
storage. This makes Singapore one of the few
countries in the world to harvest urban
stormwater on a large scale for its water
supply.
The newest reservoirs are Punggol and
Serangoon Reservoirs which are our 16th and
17th reservoirs. By 2011, the water catchment
area has increased from half to two-thirds of
Singapore’s land surface with the completion of
the Marina, Punggol and Serangoon reservoirs.
With all the major estuaries already dammed to
create reservoirs, PUB aims to harness water
from the remaining streams and rivulets near
the shoreline using technology that can treat
water of varying salinity. This will boost
Singapore’s water catchment area to 90% by
2060.
