The Water Efficiency Labelling and Standards (WELS) scheme's objectives are to conserve water supplies by reducing consumption, through providing information to consumers about the water efficiency of products and by promoting the adoption of water efficient technologies.
To achieve these objectives, the scheme requires designated water-using products to display, at the point of sale, a star rating of their water efficiency and information about the amount of water used. The scheme can also set minimum water efficiency standards for these products.
Currently the scheme covers lavatory equipment, clothes washing machines, dishwashers, urinals, taps, showers and flow controllers. These products must display, at the point of sale, a star rating of their water efficiency and information about the volume of water used. Toilets and washing machines also have minimum water efficiency standards. These products must be registered with the WELS regulator before being offered for sale.
