WELS water rating

The Water Efficiency Labelling and Standards (WELS) scheme is an Australian government initiative, in partnership with state and territory governments, designed to reduce urban water demand and consumption by specifying and enforcing efficiency standards and labels on water using appliances, fixtures and fittings.

The purpose of the WELS scheme is to conserve water by helping consumers make informed decisions and encouraging uptake of water-saving technologies. The WELS scheme is administered by the Department of Agriculture, Water and the Environment. For further information about WELS, including how to register your product, go to www.waterrating.gov.au
