I am sad there are still too many sg citixens, incl some learned
one,
think that SG is heavily dependent on MY water.
I think currently is less than 30 %, as a gesture!!
In fact , we can get all the water in--house!
u read trace the water data here

Water
Resource Management
2008, sale of potable water 1,262,000 m3 per day!THis is on par
with 2002,
thanks to NEWater and desalination water.
May i recap the water policy when NEWater was rolled
out.
----By 2011,15 % of water will be supplied by NEWater.This was
increased to
30% by 2011!
----10 % of demand is met by desalination. The plant is sold to
city spring REIT.
---Before the operation of Marina Reservoir, half of SG land is
used as water catchment area. This result in local catchment can
provide 50% of water demand.
This include some HDB estates.
After the Marina Reservoir was put in op few months ago,
catchment increase to two third of sg land. So, i think the local
catchment will provide at least two third of water demand. It may
take 2 years to dilute the salt in Marina Reservoir.The most
densely populated of SG,including CBD, fall into the new water
catchment. Urban catchment is not new. But Sg scale is very
huge.

water
catchment area of proposed Reservoirs of Marina,Sg Puggol ,
Sg Serangoon and and Lower Seletar.All the new and extended
reservoirs will be ready by 2012

Desalination
plant
The city spring REIT plant--built by Hyflux--cost abt S$200 m
and abt 6 ha to provide
10 % of SG daily need, capacity 135,000 m3 per day.
$$ is not a problem.Land--sg have new reclamation land of abt
2,000 ha in Tuas.
So, in overnight, all water demand can be met by
desalination!!
NEWater is
mainly for factory and office
Currently, only 1 % of potable come from NEWater,after it mix
with traditional source of water in reservoir for sun bath! It will
increase to 2.5 % within few years.
In USA Cali. ,they return the treated water to underground to
mix with underground water.SG is better with additional sun
bath!
SG factory need highh volume of pure clean water for
manufacturing of wafer chips, petroleum products, cleaning etc.
Office aldo need. In new Marina South new CBD, all new office
bhilding are mandatory
to be provided with chilled water for air cond purposes.
Pl read
before NEWater and desalination, 50 % of water come from local
catchment.
This will increase to abt 65%.
NEWater replace .........30%
desalination..................10%
total............................105%!!
dunt forget we have many in house recycle water.
eg power generators and rubbish disposal plant now can also
generate water and steam with heat during the process. They
call tri generation...

re opening post--
how much water the first treaty provide daily?
There is no point to discuss if we have not get the figures
right.
