About this file
This is a material standard specification document issued by the San Antonio Water System (SAWS) in Texas for ductile iron pipe procurement. The specification covers 3-inch through 64-inch ductile-iron pipe, centrifugally cast for water or other liquids, with push-on or mechanical joints. All pipe must conform to ANSI/AWWA Standard C151/A21.51.91 or the latest revision thereof. The specification establishes pressure classes based on pipe diameter, ranging from 350 psi for 3-inch through 12-inch pipe to 150 psi for 30-inch through 64-inch pipe, with intermediate classes for 16-inch, 20-inch, and 24-inch diameters. All pipe shall have a nominal laying length of 20 feet with interior cement mortar lining per ANSI/AWWA C104/A21.4 standards and exterior asphaltic coating. Rubber joint gaskets must comply with ANSI/AWWA C111/A21.11 standards, and each pipe length shall bear identification markings in accordance with AWWA C151.
The specification requires manufacturer quality-control testing and documentation as outlined in AWWA C151 Section 51.14, with SAWS reserving the right to subject random pipe lengths to independent laboratory testing at no manufacturer cost, with rejection of the entire order possible for defects or non-compliance. The approved manufacturer list includes American Griffin, U.S. Pipe Company, Clow Water Systems Company, Atlantic States Cast Iron Pipe Company, Pacific States Cast Iron Pipe Company, and McWane Cast Iron Pipe Company. The related solicitation is for 10-inch ductile iron pipe, with all bids required to comply with SAWS Material Standard Specification 05-11 (Revised December 2011) and be included on the SAWS Approved Product List dated January 2026.
