We take our environmental responsibility seriously. The Water Efficiency Labelling Scheme (WELS) is designed to provide information through labelling at the point of sale, to consumers buying the products that use water. The purpose of the label is to help consumers choose products that use less water but still provide a satisfactory level of quality and performance.
The WELS Scheme applies to showers intended solely for personal bathing as specified in AS/NZS 3662:2005 – Performance of showers for bathing. Showers generate about 25 per cent of water savings under the WELS Scheme because:
Under the WELS Scheme a rating is given to a showerhead and any additional component supplied with the head such as pivoting arm, flexible hose or flow controller. However, additional components cannot be rated separately from the head.
The WELS Scheme applies to any tap or tap outlet for use over a basin, ablution trough, kitchen sink or laundry tub as specified in AS/NZS 3718:2005, Water supply-Tap ware. WELS taps save water because:
The WELS label displays two key pieces of information:
Each product label displays a star rating out of six. The more stars the more water efficient. At the moment, showers will only have a maximum rating of three stars, while the other product types can achieve up to six stars. This is because New Zealand and Australia do not yet have a laboratory test to ensure that very low-flow shower products will deliver acceptable performance.
All WELS labels have a water consumption or flow figure in
WELS does not apply to: Bath mixers, Shower mixers or bath spouts.
