Abstract: A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the large diameter and footage of the pipe required for a new pipeline and the logistics of the PCCP suppliers, it was felt that competition for this project could be severely curtailed. A general overview of alternative pipe materials, capable of meeting or exceeding the project parameters, were therefore evaluated. In the 66-inch through 90-inch diameter range required of this project, there are only a limited number of products that have been developed for pressure conditions. This paper presents a product review of engineering and construction considerations for PCCP and steel pipe.
