Singapore has many similarities with Hong Kong when it comes to fresh water, except that national security often dominates the drive to explore and implement non-conventional sources of water. In its Singapore Green Plan announced in 2002, the city has already laid down a clear strategy on how to maintain and diversify its water supply. One of its most talked-about projects is NEWater, which turns sewage into pure water that the city-state boasts exceeds the drinking standard set by the World Health Organisation and the United States' Environmental Protection Agency. It aims to provide 250,000 cubic metres of NEWater, or 15 per cent of its water needs, by 2010. But getting the public used to drinking sewage-turned-water will take a long time, even after top officials personally tasted the water in public - and that's why most of the recycled water is now for industrial and commercial use. Apart from that, the city is striving to have 5 per cent of its water supply provided by seawater desalination by 2011. A new freshwater reservoir will also be built in Marina Basin to store up more rainwater, while the catchment areas will be expanded from a half to two-thirds of the size of the city. On controlling demand, the city requires non-commercial premises to install water-saving devices. It has also stepped up public education at the grass-roots level to save water through its water efficient home programme.
