Both reservoirs and standpipes are ground-level water storage tanks that can be built to virtually any capacity and dimension. Reservoirs have a greater diameter than height, and standpipes have a greater height than diameter.

Over the past century, CB&I has built thousands of reservoirs and standpipes that have provided many decades of service. These tanks have ranged in capacity from under 1,000,000 gallons to 34,000,000 gallons.

A full-service solution. Our specialty is providing lump-sum, turnkey EPC services to the water industry. We have the in-house resources to self-perform all facets of water storage projects, including preliminary planning, design, foundation construction, fabrication, tank construction, painting and maintenance.

Our single-source approach allows us to control costs, shorten project schedules and ensure every step of the project is carried out according to our quality standards. With one of best safety records in the industry, we reduce the tank owner's risk.

Choosing a tank option. We assist customers in selecting the best tank configuration for their requirements. Reservoirs offer economical and effective storage, especially when located on high ground. Because they have lower profiles, they can easily be concealed by foliage. Standpipes' taller design allows water above the operating range to typically provide gravity-fed pressure; the water below the standpipes' operating range provides reserve storage.

Our reservoirs and standpipes are constructed entirely of welded steel. One of the greatest advantages of welded steel tanks, compared with bolted steel or concrete tanks, is that they provide leak-free service. Properly maintained and operated, welded steel tanks offer an extremely long life and are well suited for high seismic zones or high wind load applications. Some steel tanks have been in service for more than 100 years.

A variety of options. We design our tanks with a number of standard features such as manholes, painted ladders, overflow to grade, anti-climb guards, roof handrails, fail-safe roof vents, and inlets/outlets with silt stops. Tanks can be designed with ellipsoidal, toriconical, dome or cone roofs. We also offer a variety of optional features such as lettering, logos and decorative graphics; decorative pilasters; safety cages; balconies; external lighting; telemetry; and cathodic and lightning protection.

Other tank options include our patented FreshMix circulation system. Our FreshMix system helps ensure that fresh water and chlorine residual are maintained throughout, eliminating taste and odor problems that may result from stagnation.

Throughout the water industry, we are regarded as a leader in the design and construction of water storage tanks. We pioneered the transition to welded steel tanks in the 1930s, designed and constructed the world's largest steel reservoir in 1986 and pioneered the bent-plate roof option, which eliminates the need for seal welding and reduces areas where corrosion may occur.  Contact:
