One to be run privately, the other, by PUB
SINGAPORE will have two desalination plants come
2005, one operated by the private sector, and a
smaller one operated by the Public Utilities Board
(PUB), said Minister for Trade and Industry George
Yeo.
Announcing a change to the Government's plans, he
said the privately-operated plant, for which tenders
will be called early next year, will supply about 20
million gallons per day (mgd) of water by 2005. The
PUB plant will supply 10 mgd.
He agreed with Mr Leong Horn Kee (Bishan-Toa
Payoh GRC) and Mr Ahmad Magad (Pasir Ris
GRC) that the private sector should take part in the
supply of desalinated water.
So, instead of the PUB building and developing all the
desalination capacity on its own, it will commit itself to
buying a minimum amount of desalinated water for a
minimum period of time. The private sector will then
be invited to bid for the supply contracts.
The tenderers will be free to choose the best
desalination technology and optimum plant size to
meet the Government's requirements.
The PUB will then choose the best option or options
from the bids received. This will lower the cost for
consumers and open up a wider range of desalination
technologies.
Brigadier-General (NS) Yeo assured MPs that
Singapore has enough water for its needs.
Technological advancement is working in favour of
Singapore. Desalination is already affordable and is
likely to become cheaper.
PUB had originally wanted a 30 mgd plant that will
use the multi-stage flash (MSF) distillation technology,
but recent experiences in the US and Europe show
that technologies such as reverse osmosis and
multi-effect distillation are becoming cheaper. All
these methods involve converting seawater into
drinking water.
Using the reverse osmosis process, the price of
recently-contracted water has come down to
between 84 cents and $1.20 per cu m, compared to
about $2 per cu m, using the MSF method.
Since the MSF method may no longer provide the
most cost-effective solution, the Government has
decided to change its original decision and leave the
choice of technology for the new desalination plant
open, he added.
In a column last month, Straits Times journalist
Dominic Nathan had urged the PUB to just specify
the quality and quantity of water it wants and leave
the technology for Singapore's first desalination plant
to the project's tenderers.
Deputy Prime Minister Tony Tan commended the
proposal as a sensible one and said he would urge the
PUB to take it up.
