Note on Storage Tank Upgrades & Water Quality FAQs

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 constructed a new storage tank, which we put into service in July of 2022. 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 standards for coating materials.
