10-Litre Challenge

The 10-Litre Challenge was introduced in 2006 to encourage Singaporeans to reduce their daily water consumption by 10 litres.

Besides introducing useful tips on how to save water through a one-stop edutainment website portal, the programme also includes other initiatives such as Water Efficient Homes programme, Water Volunteer Groups programme, a labelling scheme for water-efficient appliances, and promoting the use of dual-flush low-capacity flushing cisterns.

Under the 10-Litre Challenge, PUB extended the Water Efficient Homes (WEH) programme launched in all 84 constituencies since 2003 to focus on homes with high consumption. Under this enhanced programme, PUB officers visit households in Singapore with high consumption to install free-of-charge water saving devices such as thimbles and cistern water saving bags and offer advice on good water conservation practices.

Under the Water Volunteer Groups (WVG) programme, 72 WVGs have been formed since 2006 and they have been visiting households and assisting in the installation of water-saving devices in 41 constituencies.

The 10-Litre Challenge also includes the labeling of water products, which gives consumers information on the water efficiency of products to allow them to make well-informed choices at the point of sale. PUB’s voluntary water efficiency labelling scheme, launched in 2006, has labeled about 600 taps, showerheads and washing machines. To enhance the scheme, PUB will make labelling mandatory for taps, flushing cisterns and urinals with effect from July 09. The scheme may be extended to showerheads and washing machines in future, when more water efficient models are available.

The use of dual-flush low-capacity flushing cisterns will also be made mandatory for all domestic premises from July 09.
