What is the Water Efficiency Labelling Scheme?
The Water Efficiency Labelling Scheme (WELS) was developed by the Public Utilities Board (PUB), Singapore's national water agency. The scheme provides consumers with information relating to the water efficiency level of products, so they can make informed purchasing choices and encourage vendors to offer more water-efficient products.
TÜV SÜD is an ISO 17065 accredited Certification Body and accredited ISO 17025 testing laboratory for WELS. We offer WELS certification services to suppliers and manufacturers for their water fittings and appliances that require compliance with the water efficiency requirements stipulated in the Public Utilities (Water Supply) Regulations. The criteria for WELS certification are in accordance to the PUB WELS Guidebook and SAC CT 19: SAC Criteria for Certification Bodies.
Currently, there are four categories for the ratings. The rating provided is category-specific, determined by each category’s flow rate/flush capacity/water consumption. The more ticks a product has, the more water-efficient it is.
Mandatory WELS applies to the following products:
• Basin taps and mixers.
• Clothes washing machines for household use.
• Flush valves with WC pan (litres per flush).
• Dual-flush low capacity flushing cisterns.
• Shower taps and mixers.
• Sink/bib taps and mixers.
• Urinal flush valves and waterless urinals.
