Overview

Four National Taps Provide Water for All

In just four decades, Singapore has overcome water shortages despite its lack of natural water resources and pollution in its rivers.

Driven by a vision of what it takes to be sustainable in water, Singapore has been investing in research and technology. Today, the nation has built a robust, diversified and sustainable water supply from four different sources known as the Four National Taps (water from local catchment areas, imported water, reclaimed water known as NEWater and desalinated water).

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 four 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

Today, our water demand is about 380 million gallons a day (mgd). This is This is expected to double in the next 50 years, with about 70% of the demand coming from the non-domestic sector, and domestic consumption making up the other 30%.

By 2060, we plan to triple the current NEWater capacity so that NEWater can meet 50% of our future water demand. We also intend to ramp up desalination capacity by almost 10 times so that desalinated water will meet at least 30% of our water demand in the long term.
