WELS
Water Efficiency Labelling and Standards
The mandatory water-efficiency star rating shown on every Australian tap, toilet, washing machine and dishwasher.
Water Efficiency Labelling and Standards is the mandatory scheme requiring a star rating (0 to 6 stars) and litres-per-flush or litres-per-minute figure on every regulated product sold in Australia. WELS covers taps, showerheads, toilets, urinals, dishwashers and clothes washers. Higher star ratings mean less water consumed for the same performance — significant for both running costs and water bills, especially in restricted-supply states.
