In response to the increasing demand for products that help preserve the environment and conserve scarce natural resources, the Government of Singapore Public Utilities Board (PUB) has developed the Water Efficiency Labeling Scheme (WELS). The purpose of the WELS Scheme is to permit facility owners, designers and contractors to make informed decisions in selecting water-conserving equipment and products.
Under the WELS Scheme, water fittings are rated as to their water conservation characteristics. The highest rating (known as “Three Ticks”) requires that fittings deliver no more than four (4) liters of water at working pressures up to 5.5 bar (79.7 PSI). WaterSaver has developed a series of products that comply with this requirement. These products have been tested and certified by the PUB under the WELS Scheme.
