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^® and Waterspheroid^® storage tanks.

We’ve also developed a number of proprietary solutions—including our patented ClariCone™ clarifiers and FiltraCone™ plants for effective wastewater treatment and FreshMix™ and Ribbon Flow™ mixing systems for water storage tanks.

Our comprehensive approach. We provide lump-sum, turnkey design-build services for water and wastewater projects, handling everything from concept through startup. 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.

Our true EPC business model eliminates the waste and delays that can occur when multiple contractors are involved. Thus, we are able to shorten project schedules, control costs, minimize the customer’s risk and safely deliver superior-quality results. And by providing single-point responsibility for every aspect of the project, we enable our customers to focus on their core business.

Proven industry experience. As one of the oldest and most trusted companies serving the water industry, we have unparalleled experience. We’ve designed and built more than 25,000 water storage tanks for municipalities and industries around the globe. Our water treatment projects include more than 300 of our award-winning patented ClariCone solids-contact clarifiers and FiltraCone treatment systems, thousands of reservoirs and standpipes and more than 70 ESD™ egg-shaped anaerobic digesters.
