water management - singapore
  • Last night i was fortunate to view a program on TV - on how singapore
    tackles its water needs. For those not aware being a very small
    island, for long singapore has depended on a single pipeline supplying
    water from johor ( malaysia) - this runs across the causeway and has
    often been a stumbling block / negotiating tool - the british
    regiments during the second world war are said to have capitulated to
    the invading japanese - because they captured johor and turned off the
    water supply to singapore....

    Faced with a rapidly growing population and acute water shortage, what
    did singapore do??

    The main problem for singapore was not lack of water - they had more
    than adequate rains -but the biggest problem for singapore is its size
    - having a population of 4 million cramped into such a small area 692
    sq kms - there is not enough land to store water.

    So singapore embarked on three ambitions projects -


    1) Water recycling - recycle sewage - and for this they had to
    construct a brand new systems of drains - and where did they do that -
    they dug underground - sometimes 10 -11 stories deep- deeper than the
    mrt ( metro train system) and constructed monster canals to bring the
    raw sewerage to a state of art recycling plant

    2) Water desalination - using the largest reverse osmosis plant - they
    turn sea water to drinkable water

    3) Lastly and the most ambitious - mind blowing to me - as they did
    not have enough land to construct a reservoir ( pity situation in
    india with so much of area) - they came up with an ambitious project
    to dam one of their estuaries and use it as a reservoir. and at what
    scale - the Marina Barrage - With a catchment area of 10,000 hectares,
    or one-sixth the size of Singapore

    This is what good politicians can do with a bit of forethought and
    pride...

    great work. reminds me of veeraanam.
    a chola king excavates the lake using armed forces during peace ime.
    and a thousand years later it serves the capital of tamilnadu 250 km
    away.

    another tidbit.
    maladives supposedly would go into the sea in another 50 years.
    people are painting a picture of gloom. what is not reported is that
    it has already experimented on creating an atrtificial island much
    higher than sea level rises.
    their future plan is to link 16 or so islands, raise them much higher
    than sea level and create a rainfall reservoir inthe middle.
    check it out.

    Singapore has similar plans - of building a sea restraining wall all
    around its coastline...was shown in the same program. made us joke,
    only thing left would be to create a giant glass dome - would be
    straight out of a sci fi flick

Howdy, Stranger!
