Water Efficiency Labelling and Standards (WELS)


By 2021, it’s been estimated Australians could save more than one billion dollars through reduced water and energy bills by simply choosing more efficient products. The Water Efficiency Labelling and Standards (WELS) – or the “water rating label” – is an Australian government initiative to add easy to read labels to water consuming products, so consumers can choose based on water efficiency.



Having water efficient products will help to:

  • reduce domestic water use by more than 100,000 megalitres each year;
  • save more than 800,000 megalitres (more water than Sydney Harbour); and
  • reduce total greenhouse gas output by 400,000 tonnes each year – equivalent to taking 90,000 cars off the road each year.

Over one third of the water savings will come from more efficient showers, about 34 per cent from washing machines and 23 per cent from toilets and urinals.

Did you know?

A water-efficient washing machine may use only one-third the water of an inefficient model.

An old-style single-flush toilet could use up to 12 litres of water per flush, while a standard dual flush toilet uses just a quarter of this on a half-flush.

A standard showerhead may use up to 20 litres of water per minute whereas water-efficient showerhead might use as little as seven litres per minute, which is less than a third.
