Storing clean drinking water can be refreshingly simple

Health and safety requirements for drinking water systems can be complex, but sourcing a tank that meets them shouldn’t be. Engineers design water distribution and handling systems with ZCL | Xerxes potable water storage tanks, because they are manufactured with NSF 61-listed materials at our NSF 61-certified manufacturing facilities. This gives customers the assurance they need when installing storage tanks for public water systems. Xerxes quality assurance measures and facility inspections help to ensure our tanks continue to deliver reliable, high-quality performance.
