Glass-fused-to steel has become the premium leading technology in water and wastewater storage applications. STT proudly supplies Vitrium™ glass, the most durable and trusted glass coating in the industry with new Edgecoat II™ technology.

Our customers choose the Aquastore® Vitrium™ glass-fused-to-steel tank for these key reasons:

  • Lowest maintenance requirements over tank life
  • Life cycle of ~50+ years, never needs painting
  • Extremely resistant to corrosion
  • Up to ten year warranty
  • Expandable design
  • Available in diameters from 11 feet (3.3 m) to 204 feet (62.2 m) and capacity from 20,000 US gallons (75 cu m) to over 6 million US gallons (22,700 cu m)
  • Customized tank designs, options and accessories available to meet customer needs

Our tanks come with the most advanced coating technology
Edgecoat II™ technology is the ONLY process in the world that provides optimum glass encapsulation on all four sides of the sheet edges. Edgecoat II™ sheets are mechanically rounded to specific radii that provides maximum glass adhesion to steel.

The combination delivers the maximum corrosion resistance of Vitrium™ glass coating with the greatest protection on every sheet. Our Vitrium™ glass tanks are the ONLY tanks on the market that provide this process and this level of product quality.


Potable Water Storage

The Aquastore glass-fused-to-steel water tank provides the lowest life cycle cost. They are durable, easy to construct and never need repainting. Given the quality of product and NSF 61 approval, our glass tanks are the most sought after and spec’ed for water storage in the industry.

Composite Elevated Liquid Storage Tanks (CET)

When there is a need to have a tank elevated, what better product to use than a tank that never needs painting. Fast construction times, ultra-low maintenance and product longevity are just some of the features that are causing engineers to specify Aquastore CET’s.

Industrial Liquids Storage

Whether your application is to store industrial waste water or other specific industrial liquids, the strength of glass coating is best suited against corrosion from aggressive liquids. Each storage requirement is unique and we have the expertise to provide a tailored solution for each application.

Wastewater Storage

Our tanks are manufactured for low maintenance, high durability for almost every aboveground wastewater application. Aquastore tanks are utilized for clarifiers, aeration, trickling filters, sludge tanks, storm water retention tanks, flow equalizations, and sequencing batch reactor.

BioEnergy/Digesters Storage

BioEnergy and digesters are very difficult tank applications. Choosing the wrong tank and cover solution could jeopardize the performance of the biogas producing process and possibly result in serious safety risks and premature failure of the system. Choosing the right tank and cover is one of the most important decisions for a process developer or owner of a biogas production facility. With various coating options as well as various roof designs tailored to withstand pressures up to 18” WC, STT alongside our partner manufacturer CST, are the most experienced and complete storage solution provider available for digester process developers.

Landfill Leachate Storage

Aquastore tanks are manufactured using glassed-fused-to-steel technology – inert interior and exterior coating that resist corrosion by the toughest liquids. Because of Aquastore’s proprietary glass-fused-to-steel technology, our tanks outperform any other leachate storage tank. Aquastore primary and secondary tanks are flexible in design and can expand to meet your growing leachate capacity. Glass-fused-to-steel tanks require very low maintenance and never need repainting.

Power Generation

Aguastore storage tanks are perfect for boiler make-up water, de-mineralized water, fuels and liquid chemical applications in power generating facilities.

Fire Protection

Our storage tanks are the fire protection industry standard and have been installed successfully to support fire suppression systems in thousands of different locations.
