AWWA COMMENT PERIOD ON AWWA C208 – Dimensions for Fabricated Steel Water Pipe Fittings
August 12, 2022

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 Sept. 26, 2022.

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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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. 

SCOPE
This standard provides formulas to calculate overall dimensions of fittings for steel water transmission and distribution facilities. 

MAJOR REVISIONS
Major revisions made to the standard in this edition include the following:
1. Sec. 4.1.2 was modified to note nominal diameter as the basis for calculating reducer length.
2. Secs. 4.1.7, 4.1.8, and Sec. 4.1.9, and Figures 1E Case I and 1E Case II, and Figure 5, were modified to delineate lateral lower angular deflection limits based on the type of reinforcement being utilized; 45° for laterals utilizing crotch plate reinforcement and 30° for laterals not utilizing crotch plate reinforcement. The changes address potential fabrication/welding difficulties in the acute crotch of the lateral.
3. Sec. 4.1.10, minimum bifurcation angle was increased from 30° to 45°. This increase addresses potential fabrication/welding difficulties in the acute crotch of the bifurcation.
4. Figures 1A through 1E were modified to identify outlets utilizing verbiage consistent with AWWA M11.
5. Figure 2B was modified to reflect the maximum deflection angle of 30°.
