On World Water Day on 22 March 2006, PUB launched the 10-Litre Challenge.

To support the 10-Litre Challenge, PUB and the Singapore Environment Council also jointly introduced the Water Efficiency Labelling Scheme in October 2006 to encourage manufacturers and importers to come up with more innovative water-effcient products.

Under the scheme, products that are efficient in its use of water will be graded, with three ticks representing a product that uses the least water. There are currently 39 brands on the scheme, offering 337 models of water fittings.

With these water conservation initiatives, households not only save on their water bills but also contribute towards a more sustainable water supply for the nation.

These are aimed at reducing the per capita water consumption in Singapore, to meet the new national target of 155 litres per person per day by 2012, down from the current 158 litres a day.

"Although the Four National Taps are now firmly in place, we should still strive to use water wisely. Singaporeans can play their part in conserving water by using water-efficient products. The water-efficient labels on the various products will allow consumers to make an informed choice when deciding between similar models," said Mr Chong Hou Chun, PUB's Director of Water Supply Network.

A new Water Efficiency Fund was also recently launched by Dr Yaacob Ibrahim, Minister for the Environment and Water Resources to encourage more organisations, companies and industries to adopt innovative measures to promote water conservation.

Set up by PUB, the Water Efficiency Fund offers co-funding to organisations, companies, industries and community groups which implement efficient methods of managing their water consumption such as recycling of potable water, NEWater and industrial water, the use of alternative water sources such as seawater and implementing initiatives to promote water conservation in the community.

"The Water Efficiency Fund will help us reach out to those industries which are big water users because of the nature of their businesses. The fund will come in useful as putting in new and innovative water conservation initiatives may involve changing the mode of operation or putting in whole new infrastructure," said Mr Chong.
