Composite Elevated Tanks



CB&I has built more than 400 Composite Elevated Tanks (CETs) across the United States. CETs utilize the leak-proof characteristics of welded steel and the compressive strength of a concrete support column. The result is a durable and long-lasting water storage tank with minimal maintenance, reducing long-term ownership costs.

Standard CET designs have storage capacities ranging from 500,000 gallons to more than 4,000,000 gallons. We design all of our elevated tanks with internal access ladders and solid, flush threshold steel doors for added safety and security. Our standard dome-roof design minimizes the required number of internal structural members, reducing the frequency of underside corrosion and eliminating topside water ponding. The concrete pedestal exterior is aesthetically pleasing and ensures a completely dry interior. The durable exterior coating of the welded steel upper tank can be customized with logos and paint schemes.

The CET pedestal provides a flexible, multistory interior which can be configured to serve as a control room, office, meeting room, pump or fire station and equipment and machinery storage area. The CET provides sufficient space for multiple floors. Other options include decorative graphics and logos, cathodic and lightning protection, overhead doors, double personnel doors, stainless steel risers and overflows, tank drains, FAA lighting, intermediate platforms, instrumentation and telemetry.
