AQUASTORE® Elevated Water Storage Tanks
The No. 1 Choice for Municipal and Rural Water Towers
CST® has been designing and manufacturing composite elevated tanks (CETs) with Aquastore glass-fused-to-steel (enamel) tanks and concrete pedestals for decades, to the satisfaction of many customers.
Aquastore tanks have also been mounted on new and existing legged structures. CST’s composite elevated tank offerings were spurred on by the popularity of our ground storage tanks’ reputation for quality, durability and customer support, and our customers’ desire to extend these attributes toward solving traditional elevated tank challenges.
Aquastore is the most recommended water tank in rural water districts where overall cost, dependability and water quality are important attributes of water storage tanks. Larger tanks for urban use are also popular.
Right Materials, Attractive Appearance
CST knows how and when to use what materials to maximize overall storage tank performance. CST uses concrete where it performs best — as a structural member for foundations and pedestals and not as a storage tank where concrete has a long history of cracking and leaking.
Most of our customers also chose Aquastore tanks over field-welded solutions because they want to save repainting costs and don’t want to see an inevitable rusty tank high up in the air where it might reflect on the town’s image.
Aquastore tanks are coated with glass-fused-to-steel enamel. They are not painted, so they never have to be repainted – ever!
Proven Designs
Aquastore by CST has been professionally and safely designing and manufacturing elevated tanks using a combination of long-recognized and widely accepted industry standards and guidelines, including AWWA D103, ACI 371R, ACI 318, ASCE-7, AISC 360 and IBC, as well as state building codes. These designs are also PE stamped to ensure quality and safety.
Design standards are important but should be put into perspective as they relate to good, overall design practices. It is sound, experienced engineering judgment in conjunction with standards, experience, R&D, testing and empirical results that make up the good design of any engineered product, including water storage tanks.
The use of standards alone should not be a substitute for sound engineering practices. We at CST use the experience we have gained since 1893 from manufacturing thousands of tanks in over 125 countries — along with the application of new tools such as solid modeling, finite element analysis and proprietary design programs — to optimize our tank and pedestal designs.
Fast Construction
Since all of our elevated tanks are manufactured using factory-coated tanks, construction is faster. While field-welded tanks have to wait for the weather to be within certain restrictions to paint, our tank construction schedule is rarely delayed by weather. As a result, our elevated tanks can usually be constructed in two-thirds the time of a conventional field-welded elevated tank. This quick erection time and avoidance of most weather-related delays mean our projects finish on-time more often and ROI begins sooner.
Low Maintenance
When your elevated tank is built with an Aquastore glass-fused-to-steel tank and a concrete pedestal, you are getting an elevated tank solution that is constructed from some of the most durable tank and structural products in the market. Maintenance periods for glass-fused-to-steel tanks are typically 15 to 20 years and require minimal work compared to repeatedly painting a field-welded tank. This saves hundreds of thousands of dollars over the service life of the product.
The Ability to Expand
Why pay for the cost and time of building a new tank as your water needs to expand? Aquastore’s jack-built, top-down construction method makes it easy to expand your existing tank when the foundation and pedestal are designed upfront with expansion planned for the future. Because the lower rings of the tank are constructed last, it’s easy and quick to add heavy rings at the bottom of the tank to accommodate expansion.
Logos and Decorations
Aesthetics are important, and having a built-in billboard is a good thing to leverage. Whether displaying the proud heritage of a town’s logo or using the space for commercial advertising, simple and intricate logos can be included with your tank order. For long-term durability, many logos can be glassed into the tank so they can be proudly displayed for the entire life of the tank and will look as if they were almost newly applied for the life of the glass coating.
