Singapore - Four Waters Taps
Through this partnership, Singapore has involved the private sector in order to improve water supply.
Singapore has built a robust, diversified and sustainable water supply from four water sources known as the Four National Taps – water from 1) Local Catchment, 2) Imported Water, 3) high-grade reclaimed water known as NEWater and 4) Desalinated Water. In integrating the water system and maximizing the efficiency of each of the four national taps, Singapore has overcome its lack of natural water re-sources to meet the needs of a growing nation.
Singapore has through the years developed an integrated cost efficient way of meeting the country’s water demands by e.g. reusing industrial water and waste water through NEWater. Today, Singapore is internationally renowned as a model city for integrated water supply. Learn more here.
