Water & Wastewater

For more than a century, customers in the water and wastewater sectors have trusted CB&I to provide products and services that deliver superior value and unmatched reliability.

Today, we continue to meet customer needs via a full spectrum of offerings that extend from water and wastewater treatment to potable water storage, biogas generation, processing and storage as well as associated systems.


Our reputation in the design and construction of water storage is unmatched. CB&I has built more than 25,000 elevated water tanks while pioneering better tank designs. To that point, our Waterspheroid® and Hydropillar ® elevated tanks are the most popular styles in use today.

Additionally, we provide a suite of services and structures to facilitate the water treatment process, including aeration, clarification, disinfection, metals removal, softening, turbidity removal, chemical dosing, carbonation, stabilization and filtration. The design of the CB&I ClariCone solids contact clarifier makes it more economical to operate and maintain than other water treatment systems.
