Composite Elevated Water Tanks

Increasingly Popular Option For Larger Tanks

A composite elevated tank is a single concrete pedestal supporting a welded steel container. Composite tanks offer some similar benefits to spherical tanks by requiring a smaller construction footprint, having interior ladder systems, and having less painted surface area to maintain.

Composite tanks have become an increasingly popular option for larger tanks (500,000 gallons and larger) due to their pleasing aesthetic appearance, long-term maintenance costs, and storage areas available in the base of the tank pedestal. Our proprietary 7-foot forming system is the safest, most technologically advanced system in the industry and allows us to construct a superior looking pedestal. We utilize a solid interior platform that is self-elevating as the workers progress up the concrete shaft. It provides a cost-effective, superior-looking pedestal that serves well over the long term.
