AWWA Comment Period on ANSI/AWWA C302 – Reinforced Concrete Pressure Pipe, Noncylinder Type

AWWA Comment Period on ANSI/AWWA C302 – Reinforced Concrete Pressure Pipe, Noncylinder Type
October 15, 2021

AWWA solicits public comments on all proposed new AWWA Standards, and on all proposed revisions, reaffirmations, or withdrawals of existing AWWA Standards. The referenced standards project is being considered for approval and the publication of this notice begins the 45-day public comment period for AWWA and ANSI. An electronic public review copy of the proposed standard can be obtained for review during the comment period by emailing ETS Support. Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein. Such comments shall be specific to the section(s) of the standard under review and include sufficient detail so as to enable the reader to understand the commenter's position, concerns and suggested alternative language, if appropriate.

AWWA Comment Period closes on Nov. 29, 2021.

The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association

This standard describes the manufacture of circumferentially reinforced concrete pressure pipe, without a steel cylinder and not prestressed, in sizes from 12 in. to 144 in. (300 mm to 3,660 pressures not exceeding a total pressure of 65 psi (450 kPa). 

Major changes made to the standard in this edition include the following:
1.    Provisions for slag cement as a replacement for portland cement (up to 20 percent) have been added (Sec. 4.4.1).
2.    The minimum specified yield strength for cylinder steel used for fittings has changed to 36,000 psi (248.3 MPa) (Sec. 4.4.6). The minimum specified yield strength for steel used for bell rings has changed to 36,000 psi (248.3 MPa) (Sec. 4.4.8).
3.    Rubber gasket testing requirements have been added for ozone resistance (Sec. and water immersion (Sec.
4.    The maximum allowable circumferential steel stress used in the design of fittings has changed to 18,000 psi (124.2 MPa).
5.    Provisions for a quality assurance program have been added (Sec. 5.4).
6.    Updates to material requirements meeting ASTM standards have been made as appropriate throughout the standard.
