AWWA COMMENT PERIOD ON THE REVISIONS TO AWWA C218 – Liquid Coatings for Aboveground Steel Water Pipe and Fittings
November 25, 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 January 9, 2023.

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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 seven coating systems designed to protect the exterior surfaces of steel pipelines and the associated fittings used by the water supply industry in aboveground locations.

1. Added Section 1.1.2 to discuss other substrates. The change has been made to other applicable standards.
2. Section 4.1 Equipment and 4.2 Materials and Workmanship were added. These sections are standard language and included in all other similar AWWA coating standards.
3. Removed the color designations from the coating systems (i.e. -B, -W, -C for black, white and other color) in Sections 4.3.3 thought 4.3.7. This change also allowed the tables in these sections to be simplified by removing the “System” column.
4. Added a new Section 4.3.8 Coating System No. 7. ( two-coat system consisting of a prime/base coat of two-component, 100% solids aromatic polyurethane followed by a finish coat of an aliphatic polyurethane). Updated references throughout the document.
5. Section 4.3 Coating Material Information Requirements was removed. Product labeling, shelf life and safety requirements are now listed in Section 6 which is consistent with other AWWA coating standards. The other listed product information is available in the product technical data sheet.
6. Updated Section 4.4 Surface Preparation to be consistent with the language used in all other similar AWWA coating standards. The level of surface protection has not been changed.
7. Removed Section 4.5.2. The material preparation varies greatly between the different system types in this document. Manufacturer recommendations should always be followed.
8. Section 4.6 was removed and replaced with Section 4.2.3 to be consistent with other AWWA coating documents.
9. Renumbered and reformatted Sections 4.3 through 4.9 to better match other AWWA coating standards.
10. In Section 5.5.3, NACE SP0274 was added as an option for electrical continuity testing.
11. Updated Section 6 Delivery language based on common language used in recently updated coating standards. Added requirement that containers shall include shelf life and/or expiration date.
