Save Water


Save Water


Through the Four National Taps, we have a robust and sustainable water supply for Singapore. However, installing the infrastructure to supply water is only one half of the equation. As the population and economy continue to grow, Singapore needs to ensure that the demand for water does not rise at an unsustainable rate.

Achieving a sustainable level of water consumption and managing the impact of water on the environment takes the commitment and participation of the community.

Water Consumption

Water demand in Singapore is currently about 430 million gallons a day. This could likely double by 2060 with the non-domestic sector accounting for about 70% of the water demand. As PUB continues to build on water infrastructure and expand capacities, everyone is encouraged to play their part and to make water conservation a way of life.

What can you do?

Every drop counts, every contribution matters, no matter how big or small. Let’s work together to lower our water consumption from the current 148 litres to 140 litres per person per day by 2030.

Water Closet Replacement Programme for Lower Income Families

PUB will be launching a community project to help lower income families from older HDB estates (built mainly between 1986 – 1992) to replace their non-water efficient water closets which use 9 litres per flush, with more water efficient ones, free-of-charge. This replacement can immediately help these families save about 5 litres of water per full flush. They can also see a potential savings of 10% in their monthly water bill. Details on this programme will be released later in 2017.

Smart Shower Programme

PUB will be installing smart shower devices for some 10,000 new homes under a demonstration project over the next few years to further study and validate the conservation effect of such devices. These devices provide real-time information on water consumption during showers. An earlier small scale study found that a person could save up to 5 L a day or about 3% of their monthly water bill, from the use of such devices.
