Note on storage tank upgrades
As part of a seismic resiliency upgrade project, SUB recoated two of its water storage tanks, one in 2019 and one in 2020, with a specialized product suited for potable water tanks that meets the national standards for drinking water materials. SUB also construct- ed two new storage tanks, which we put into service in 2022 and 2023. Although not required, SUB has since routinely monitored the tanks for 69 volatile organic compounds. These water quality tests have confirmed adherence to the national drinking water stan-dards for coating materials.
National Sanitation Foundation (NSF) 61 Standard: Coatings are commonly used materials in potable water applications to protect storage tanks from corrosion. The NSF 61 standard certification of coating products ensures that this product will not impart harmful levels of contaminants into drinking water.
