McDermott offers special structures for water and wastewater treatment. We began offering CB&I ESD™ Egg-Shaped Digester systems in 1989, and we have made a number of advancements since that time. The CB&I Egg-Shaped Digester is one of the most efficient and cost-effective anaerobic systems for sludge treatment. In addition, McDermott is the original provider of the CB&I ClariCone® solids contact clarifier for potable water and wastewater treatment. McDermott's experience and knowledge is unparalleled, with well over 300 CB&I ClariCone installations on a variety of applications treating in excess of 700 million gallons per day. 

We provide turnkey design-build services for 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.
