American Water Works Association AWWA D110-13 (R18) Prestressed Concrete Water Tank Standard

The AWWA D110-13 (R18) standard provides essential guidance for professionals working with wire- and strand-wound, circular, prestressed concrete water-containing structures. This technical resource outlines recommended practices for the design, construction, inspection, and maintenance of these specific engineering systems. This standard covers four distinct types of core walls to assist engineers and contractors in selecting the appropriate method for their project requirements. These include cast-in-place concrete with vertical prestressed reinforcement, shotcrete with a steel diaphragm, precast concrete with a steel diaphragm, and cast-in-place concrete with a steel diaphragm. By following these industry-recognized practices, users can ensure consistency in the development and upkeep of water-containing structures. Please note that this specific standard does not cover bonded or unbonded horizontal tendons for prestressed reinforcement of the tank wall, floor, or roof.
