Water Efficiency Labelling
Saudi Arabian Standards Organization (SASO) has begun enforcement of “Technical Regulation for Water Rationalization Tools” and a SASO Water Efficiency Labelling program for faucets, showers and toilets based upon their water efficiency (high or low) consumption rates. This regulation was approved at SASO board of directors meeting No. (156) held on 16/09/1437 A.H. (21/06/2016 A.D.)


Water Efficiency Label Certificate of Conformity for Saudi Arabia
SASO Water Efficiency Labelling Program -
Water is one of the most undervalued resources in the world which is taken for granted very often. Some of it gets wasted by our own negligence and at times it is the machines, the tools, and the equipment around us that do not use it judiciously. We need to remind ourselves that saving water helps to preserve our environment and reduce the energy required to process and deliver it to homes, businesses, farms, and communities, which eventually helps to reduce pollution.
