WELS Standards and Requirements – Do You Meet Them?
The Water Efficiency Labelling Scheme (WELS) is an initiative introduced by the Public Utilities Board (PUB). In Singapore, water fittings such as Taps and Mixers must comply with the Mandatory Water Efficiency Labelling Scheme (WELS) before they can be sold, displayed or advertised for installation.
Mandatory Water Efficiency Labelling Scheme (MWELS)
The Mandatory Water Efficiency Labelling Scheme (MWELS) launched on July 1, 2009, requires water-using products for potable installations to be tested and labelled for efficiency. Only products that meet the standards can be sold and installed in Singapore. Since October 1, 2015, only products with 2-tick rating or higher are allowed for sale and installation.
| Mandatory WELS | ||
|---|---|---|
| Water Efficiency Rating | 2-tick ✓✓ | 3-tick ✓✓✓ |
| Type of fitting | Flow Rate (litres / min) | |
| Shower Taps & Mixers | > 5 to 7 | 5 or less |
| Basin Taps & Mixers | > 2 to 4 | 2 or less |
| Sink/Bib Taps & Mixer | > 4 to 6 | 4 or less |
Why WELS Matters
The Mandatory WELS is a key initiative to promote sustainable water use in Singapore by ensuring that water-consuming fixtures and appliances meet high efficiency standards, thereby reducing water wastage and supporting resource conservation.
Enforcement Measures by PUB
PUB actively monitors both physical locations and online platforms that supply water fittings. They are committed to taking strict enforcement actions against any parties that fail to comply with their regulations and requirements
