    Municipal Potable Water Storage Tanks 

    CST’s Aquastore® tanks with Vitrium™ glass-fused-to-steel (enamel) coating offer the lowest total life cycle costs. The glass coating on the tank panels never need recoated during the entire life of the tank, saving tank owners money.  This solution has quickly become the preferred choice in municipal water storage.

    CST’s HydroTec® (formerly Columbian TecTank®) tanks offer the durability of factory-coated and cured epoxy coatings using our proprietary OptiBond™ process offer a low upfront cost.  Both glass and epoxy coating options are NSF approved.

    CST’s in-house professional engineering teams and ISO certified manufacturing process allow CST covers to be custom designed to meet each customer’s specific needs.  This includes ground storage tanks in excess of 6 million gallons, composite elevated tanks greater than 2 million gallons, silos with heights exceeding 100 feet and aluminum domes and covers spanning greater than 200 feet.  CST also supplies smaller tanks and other type covers that can be manufactured and constructed safely and quickly.

    CST also offers galvanized tanks that are NSF approved. CST’s Galvanized tanks are a cost effective way of storing water when other types of tanks are not practical.
