CB&I has provided superior value and reliability to the water and wastewater industry for more than a century. We built our first elevated water storage tank in 1894, pioneered the transition to welded steel tanks in the 1930s, and developed the original Watersphere®, Waterspheroid® and Hydropillar® storage tanks.

We provide turnkey design-build services for water and wastewater projects, handling everything from concept through start-up. This approach is possible because our people have extensive hands-on expertise in all aspects of project development, from process selection and design, engineering, fabrication and procurement to foundations work, construction and painting.

Water storage. Our record in the design and construction of water storage is unmatched. Over the past century, CB&I has built more than 25,000 elevated water tanks, pioneered better tank designs and storage technologies, and developed a unique trailing scaffold system that makes construction safer and more efficient while improving inspection access. Our Waterspheroid® and Hydropillar® elevated tanks are the most popular styles in use today, and we also supply cost-effective Composite Elevated Tanks that combine a reinforced concrete support pedestal with a steel tank. In addition, we design and build reservoirs and standpipes – ground-level tanks that can be built to virtually any capacity and dimension.
