Water ratings

Since 1 July 2006, water efficiency labelling for water-related fixtures and appliances has been mandatory. Under the Water Efficiency Labelling and Standards Scheme (WELS) all toilets, showerheads, taps, clothes washers and dishwashers are registered and rated in accordance with Australian and New Zealand Standard AS/NZS6400:2005 and must be labelled to show their water efficiency before they may be supplied for sale in Australia.

The label shows:

  • A zero to six star rating that allows a quick comparative assessment of the product's water efficiency.
  • A figure relating to the water consumption/flow rate of the product, based on laboratory tests.

Products included in the BASIX calculations and currently covered by the WELS scheme include:

  • Showerheads
  • Taps and tap outlets
  • Toilet suites or matched cistern and pan sets
  • Appliances (unit developments only)

The more stars a water fixture or appliance has, the greater the water efficiency of that fixture and the greater the savings achieved towards the BASIX water target.

In addition, choosing more water efficient hotwater-using fixtures, such as showerheads and taps will have a positive impact on the energy score of your development in BASIX
