WHAT IS THE WATER EFFICIENCY LABELLING SCHEME (WELS)?

TÜV SÜD PSB offers the Water Efficiency Labelling Scheme (WELS) Certification to suppliers, manufacturers seeking certification of their water fittings, apparatuses, and products for compliance with the Water Efficiency requirements stipulated in the Public Utilities (Water Supply) Regulations. The criteria for certification is in accordance with the PUB Water Efficiency Labelling Scheme (WELS) Guidebook and SAC CT 19 : SAC Criteria for Certification Bodies (Water Efficiency Labelling Scheme).

TÜV SÜD PSB is an ISO 17065 accredited Certification Body and accredited ISO 17025 testing laboratory for Water Efficiency Labelling Scheme (WELS). We can ensure customers comply with PUB’s specified guidelines and regulations regarding minimum performance and water efficiency requirements.

WHAT ARE THE BENEFITS OF WELS?

The Water Efficiency Labelling Scheme (WELS) provides consumers with the necessary information on water efficiency. With this scheme, consumers can make informed choices when making purchases and encourage vendors to offer more water-efficient products in Singapore. 

Currently, there are 4 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. Learn more about the Types of Labels here.
