Overview

Four National Taps Provide Water for All

 


Quest for a Diversified and Sustainable Supply of Water

Over the last 50 years, through strategic planning and investment in research and technology, Singapore’s national water agency PUB has built a robust and diversified supply of water known as the ‘Four National Taps’. The water supply comprises (1) Local Catchment Water, (2) Imported Water, (3) highly-purified reclaimed water known as NEWater, and (4) Desalinated Water. Both NEWater and Desalinated Water augment our water supply, allowing Singapore to be more resilient to weather variability.

By integrating the system and maximising the efficiency of each of the four taps, Singapore has ensured a stable, sustainable water supply capable of catering to the country’s continued growth.

Closing The Water Loop

From rainwater collection to used water treatment, the entire water loop is managed by PUB.

Safe To Drink From the Tap

Due to sound watershed management, effective water treatment processes and continued investments in R&D, Singaporeans have been enjoying good quality water for the last five decades.

Singapore’s tap water is well within the World Health Organisation drinking water guidelines, and is suitable for drinking without any further filtration.

Planning for the Future

Water demand in Singapore is currently about 400 million gallons a day (mgd), with homes consuming 45% and the non-domestic sector taking up the rest. By 2060, total demand could almost double, with the non-domestic sector accounting for about 70%. On the supply side, we are on track to more than triple our NEWater capacity and ramp up desalination. Together, these will be able to meet up to 80% of water demand in 2060.
