Drinking Water

NSF-61 was developed by the National Sanitation Foundation (NSF), a global independent public health and environmental organization, and the American National Standards Institute (ANSI), which oversees the consensus for developing standards for manufacturing and procedures in the United States. Designs can accommodate secure tank storage for local environmental conditions, such as high wind speeds, snow or seismic loads. NSF/ANSI Standard 61 (NSF-61) is a set of national standards that relates to water treatment and establishes stringent requirements for the control of equipment that comes in contact with either potable water or products that support the production of potable water. Drinking Water Inspectorate Water – Regulation 31 ensures that water suppliers, when producing and distributing drinking water, only use products and substances that do not cause any detrimental effects on the safety or quality of the drinking water”.
