Singapore is 100 per cent served by modern sanitation today. Used water is collected through a network of sewers that leads to the water reclamation plants. Currently, there are four water reclamation plants serving a population of over 5 million.
Each year, about 595 million cubic metres (m3) of used water, equivalent to 238,000 Olympic-size swimming pools, is treated to international standards stipulated by the U.S Environmental Protection Agency and World Health Organisation.
