Singapore's Mandatory Water Efficiency Labelling Scheme (MWELS) for shower/basin/sink 
taps and mixers was introduced in 2009. Under the Scheme, all shower/basin/sink taps 
and mixers must be registered and labelled to provide information on their water efficiency level before they can be sold or supplied in Singapore. A rating system of 0/1/2/3 ticks is used to reflect the water efficiency level of such shower/basin/sink taps and mixers. 
PUB regularly reviews the water efficiency stan dard of water fittings and appliances. Since 
the introduction of mandatory water efficiency labelling for taps and mixers in 2009, the market has shifted towards more water efficient products. To improve water efficiency, 
PUB intends to introduce minimum water efficiency standards for taps/mixers from 
31 March 2017, i.e. only taps/mixers with at least a 1-tick rating are allowed to be sold/supplied. 
7. Objective and rationale, including the nature of urgent problems where applicable: 
For the purposes of water conservation as part of an overall effort to strengthen the sustainability of Singapore's water resources. Taps and mixers accounts for a large part of 
water usage, especially in households. The new requirement would help moderate water 
use in this area and also benefit consumers in terms of cost savings from the use of more efficient taps/mixers.
