AWWA COMMENT PERIOD ON AWWA C6CC, Continuous, Close-Fit, and Segmental Sliplining

November 6, 2026

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 (ETSsupport@awwa.org). 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 December 21, 2026.

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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 describes the selection, planning, design, installation and inspection requirements for continuous, close-fit, and segmental sliplining for transmission and distribution pressure pipe rehabilitation applications. Sliplining is a rehabilitation method used to restore structural integrity and performance to the host pipe with limited surface and subsurface disruptions. Conventional sliplining involves the insertion of new product pipes that have an outside diameter smaller than the inside diameter of the host pipe. Close-fit sliplining products have outside diameters equal to

the host pipe inside diameter when installation is complete, with their cross section either manufactured or temporarily reduced to enable insertion.

MAJOR REVISIONS This is the first edition of this standard.
