Unlike some countries however, Singaporeans don't manage by crisis...
As a first step, a string of massive reservoirs are being constructed to "harvest as much rain as possible", so that eventually, some two-thirds of the island's land surface will be under water, up from about half today, [Public Utilities Board Chief Executive Khoo Teng Chye] explains.
In addition, desalination plants that turn salt water into drinking water provide 10% of Singapore's current needs.
But the real breakthrough has come from what Mr Khoo describes as NEWater, produced in water reclamation plants from so-called "used" water.
Contrast this foresight to the primitivism of Filipinos where, according to an Earth Times News report on the water crisis faced by the Philippine capital today, 3.5 million residents suffer from an acute supply shortage. That's almost 80 percent of the population of Singapore.
