Tank sheets are shipped on protective skids, with crated hardware and accessories. At the jobsite, tanks are installed by Greatario Engineered Storage Systems, using specialized equipment. The tanks are assembled from the top down with a jacking system that progressively elevates the structure.

Potable Water

Whether multiple tanks over 5MM gallons or a single tank of 5,000 gallons, Greatario water tanks provide the lowest life cycle cost. They are durable, easy to construct and never need to be recoated.

Composite Elevated

What better place to have a tank that never needs painting than 100 feet up in the air. Fast construction times, ultralow maintenance and expandability are just some of the features that are causing engineers to specify Greatario CET’s.

Industrial Liquids

When ease of cleaning, durability and contamination avoidance are important concerns, glass enamel coating is the choice.



Glass-fused-to-steel porcelain enamel technology is the preferred choice of digester and bioenergy process developers worldwide.


Low maintenance, high durability tanks for almost every aboveground wastewater application. Greatario tanks are utilized for clarifiers, aeration, trickling filters and many other processes.
