Four National Taps


Four National Taps 

Singapore has built a robust, diversified and sustainable water supply from four water sources known as the Four National Taps – Water from Local Catchment , Imported Water, high-grade reclaimed water known as NEWater and Desalinated Water.  In integrating the water system and maximising the efficiency of each of the four national taps, Singapore has overcome its lack of natural water resources to meet the needs of a growing nation.

It also reinforces the need for continual investment in R&D on water technology to seek more cost-effective ways of treating, recycling and supplying water. Most of all, it is about how everyone in Singapore has a stake in water – as a necessary resource, an economic asset and an environmental treasure.
