In the article, “Singapore Water Story (2020) that was adapted
from the Public
Utilities Board’s (PUB) websites, PUB reports that there is a demand for water
continues to increase in tandem with population and economic growth. Which PUB
add on that Singapore’s total water demand could almost double in coming future
and it has also included the strategies and actions that is needed to be done
to meet the water demand. In addition, Singapore is internationally being
recognised as a model city for water management and emerging a Global Hydrohub,
where Singapore have come out with ways and ideas.
Water from
Local Catchment, Imported Water, NEWater, and Desalinated Water, these are the ways
where Singapore are doing to meet the huge demand. Water from Local Catchment, where
there is two separate collection system. Where one of it is collection of
rainwater, collection from drains, canals and rivers and it channelled to the
reservoirs before it is treated for drinking water. Another is collection of
used water from underground sewers that lead to a water reclamation plant.
Thus, in result, with this idea of Water from Local Catchment, Singapore has a
total of 17 reservoirs in total here. In which is a good plan for Singapore as
it is efficient and affordable. Also, we can say that is a 3 Recycle process
(3R), reduce, reuse, and recycle. In addition, two-thirds of Singapore’s
surface area is classified as protected drainage basins, with regulated land
use which facilitates the collection of rainwater However, the downfall is
that, to use this idea, we are depending on the rainfall of the country which
so far, there is no negative impact on the rainfall in Singapore.
Imported
Water, Singapore has an agreement with the Johor State Government. These
agreements which expires in 2011 and 2061 which allows Singapore to draw up to
250 mgd. Where Singapore brings in, and treatment the water, which allows
people to drink and uses for daily life. It can be said as one of the taps with
an expiry dates which it gives an addition to the water supply to Singapore.
NEWater and
Desalinated water, where NEWater is a name given by PUB to highly treated reclaimed wastewater and is an
treatment technologies where process of microfiltration and reverse osmosis membranes, and ultraviolet
irradiation. This water is for daily usage and drinking water supply reservoirs
where it is withdrawn and treated again in conventional water treatment plants
before being distributed to consumers. Desalinated Water come along, is where
the NEWater process come from. There are three desalination plants, SingSpring
Desainatiom Plant, Tuas South Desalination Plant and Tuas Desalination Plant,
with a combined capacity of 130 mgd that can meet up to 30% of Singapore’s
current water demand. With, two more desalination plants will be ready by
2020 which expected to meet up to 30% of Singapore’s future water needs by
2060.
Thus, with
all the strategies that Singapore have taken and planned, in conclusion I
believed that Singapore is ready and meet the water demand in future. Perhaps,
these strategies also help Singapore to have a backup plan which let just say
that in future the Singapore is impact with tragedy and Singapore being an
independence country. Which made the people to be less worry about the water
supply here in Singapore.
