Over the last decade, the cost of a cubic metre of reclaimed used water has gone down from 80 US cents to 20 US cents, and desalinated water from 1.50 US dollars to 50 US cents. Such dramatic reductions in the cost of water are the results of Singapore's investments in research on water technology, said the chairman of the National Research Foundation Tony Tan. Used water is recycled and seawater desalinated using advanced membrane technology. Singapore is also progressively building a desalination plant using seawater reverse osmosis (SWRO) membrane technology. This can supply a maximum of 30 million gallons of drinking water per day. When that happens, it will bring Singapore closer to meeting the target of having non-conventional sources of water making up at least 30 per cent of the country's water needs by 2012.

Through these technologies it have broadened the possible sources for water-scare nations, like Singapore, to provide this critical resource to the people. Singapore need not depend so much on water supply from other countries. Singapore will also have
