No need worry
about water supply
Before the NEWater and first desalination plant built by
Hyflux
(the Hyflux plant subsequently
sold to Cityspring),50% of water demand came from Malaysia.see
A
Let us see how SG to replace this 50%.
U wil say hi the demand will be increased.
I will answer u later.Currently,i estmate not more than 40% of water
comes from Malaysia.
Malaysia water,accounting for 50% of demand as at
2001,
have been replaced and will be replaced
by:
30 % of SG demand by 2011:Few NEWater plants completed.30% when
Changi
.................................WRP completed .15% currently from
NEWater.
10% of SG demand: Hyflux Desalination Plant was completed in
2002.
7% desalination:Tuas Power 4-in-1 plant by 2011.
10% of SG demand:from increase of catchment area fr half of SG to
two-third.
.........(Completion circa 2011.assume new catchment of 100 km2 not
so effective.But May be .............more effective than existing
catchment.)
8% of SG demand: from intergration of reservoirs est completion
2010.
10% of SG demand:from variable salinity plant which is in large
scale demonstration level
If successful, it can potentially increase the water
catchment area in Singapore from 67 per cent to 90 per
cent.
let say also not so effective,
say 10 % of SG demand.
TOTAL:75% increase of suppply able to
replace Malaysia's supply of 50%
in 2001 .Currently is estimated at not more than
40%.Hyflux desalination plant replaces the
10%!!
Sales of
potable water still less than 2002
waste water can be treated to make NEWater and Industrial
water.
Therefore,we just need to concern supply of raw water for
potable water.
u may heard gavaman mentioned of 300 million gallon per day of
water demand.
This include potable water and Industrial water,before NEWater
and desalination
kicked in.This is equal to 1,320,000 cubic meter or 1.32 million
m3.
In the beginning of this century,gavaman estimated water demand
increase
to 400 mgd in 2011!!They are wrong for good and expected
reasons--
advance in NEWater and desalination technology!!
Drops in water sales in 2002 to 2004 may be caused by bad
economy!!
Not a good news.

History of
Catchment areas
Again,SG is one of the first countries to use highly urbanized
areas
as water catchement areas.Any problems of the water?
Look at your old aged grand/parents.Are they ok?
Currently,half of the main Island is catchment which
provides
half of water demand,ie about half of 1,250,000 m3 a day!!
Read the maps in this pagev for coverage of catchment.
Dunt litter for good reasons--dunt polluate your own drinking
water!!
NOTE:
A.We can confirm from Malaysia that only half from MY!!

B.NEWater is ultra pure water for
manufacturing,washing,cooling,
air--conditioning(District Cooling Plant in CBD),making of IC
wafers etc
C.Industrial water---lower grade water for industrail uses
