CST is the world’s largest manufacturer of factory-coated storage tanks and clear-span aluminum covers for municipal and industrial water and wastewater applications.

    Wastewater applications demand rigorous tank performance that also complies with strict environmental standards and regulations.  CST provides a complete line of integrated storage solutions that offer worry-free, long lasting and high quality results.  CST tanks and domes are corrosion resistant with low lifetime maintenance cost.  All our wastewater products are manufactured in ISO Certified facilities under the closest production controls.

    CST is home to world-class brands including Aquastore®, HydroTec® (formerly Columbian TecTank®) and OptiDome®.  To date over 350,000 tanks and 18,000 covers have been installed in more than 125 countries around the world.

    CST’s water storage tanks are the preferred storage tanks for potable water storage and are available in bolted and welded designs, capacities of 4,000 to more than 6 million gallons and in-ground, standpipe or elevated configurations.

    Aquastore glass-fused-to-steel tanks are the premium technology in the tank market.  Aquastore owners choose glass-fused-to-steel technology over other tank designs for several reasons.

    • CST designs innovative clear-span aluminum covers for wastewater process and water storage tanks that help control odorous emissions and prevent water intrusion.  CST’s aluminum domes and flat panel covers provide the strength, durability, odor control and protection characteristics unavailable in steel, plastic, fabric or any other materials of construction.

    • Water, wastewater plants and storage facilities are increasingly turning to the CST Aluminum Advantage.  In addition to low maintenance, low cost and low profile advantages, CST aluminum domes and reservoir covers are versatile enough to permit a wide range of accessories important to the water, reservoir and wastewater industry.  Using proprietary design software CST’s aluminum domes and tank covers are noted for their ability to meet exacting live load requirements by providing greater stiffness and strength, pound-for-pound, than any other dome geometry system.
