A composite tank is a modern tank that comprises of a concrete pedestal reinforced by steel, and its interior made up of steel. The composite water tank has two major specification that buyers and tend to focus on, and these are the method of construction and qualification of the contractor.


This is majorly on the pedestal form height. The standard set by the ACI and AWWA does not limit the height of the concrete pedestal form, as the height of the pedestal form can be raised to any level as desired. There are different form systems used by different composite water tank suppliers, using different materials like wood, steel, or composite, and height ranges from 4-inches to any height specified. Also note that the curved shape of the composite is gotten from curved prefabricated segments that is designed to withstand full height plastic pressure and, at the same time, show a uniform horizontal and vertical pattern for architectural beauty. Standards set by the ACI make sure that the pedestal form height of the composite water tank is constructed properly and the concrete of the tank is placed properly irrespective of the height the contractor uses. Allowing the contractors use their own specifications and equipment ensures the construction is of top quality.


Hiring a contractor with seasoned and experienced engineers ensure a higher quality job done. The engineers must be professional with CET experience, and licensed by the state in which the project is constructed. The qualifications of the engineers should be stated in the specifications. With an average size of 500,000 gallons, most CET’s today have tank sizes ranging from 2.5 million gallons or more. Constructing tanks of these sizes need experienced engineers. The specifications of the tank is written to a similar capacity and not the real capacity. This increases the flexibility of the construction by reducing errors of making the tank larger or smaller.

For a long time, owners and engineers have decided the specifications of the project. The AWWA standards committee has now released a standard for designing and constructing a composite water tank. This makes the construction process as accurate as possible, making the construction as safe as possible for the owner. The bidding of the project should be done by qualified contractors. This makes the contractors use their own method of construction, leaving no room to errors and mistakes, and therefore enhancing the tank’s quality.
