The Water Efficiency Labelling Scheme (WELS) is a mandatory scheme (since 2009), managed by the Singapore Public Utility Board (PUB). From 1 April 2018, all water fittings, appliances, apparatuses and products covered under WELS must be certified by an Accredited CB for WELS. Element’s Singapore Sungei Kadut Loop and Malaysia Johor teams can help provide this certification.

The scheme applies to all water fittings such as pipes, pipe fittings, valves, taps/mixers, urinal flush valves/waterless urinals, flush valves for WCs, dual-flush low capacity flushing cisterns, etc. for use in potable water service installations in Singapore. Additionally, water fittings such as taps/mixers, dual-flush low capacity flushing cisterns, urinal flush valves/ waterless urinal and appliances such as clothes washing machines must be labelled under the Mandatory Water Efficiency Labelling Scheme (WELS) before they can be offered for sale, displayed or advertised for sale/supply in Singapore.
