(1) Mandatory WELS Stage 1

The voluntary Water Efficiency Labelling Scheme (WELS) was launched in 2009. The scheme currently covers 6 types of plumbing fixtures and water-consuming devices under a grading system. In 2017, the WSD launched the requirements for mandatory use of devices under the WELS, meaning that for plumbing works for kitchens of domestic premises as well as for bathrooms and toilets of all premises that involve installation of showers for bathing, water taps and urinal flushing valves, models of devices registered under the WELS should be used. There was a one-year grace period. Starting from 1 February 2018, the Water Authority only accepts plumbing works applications that comply with the above requirements.
