American Water Works Association Releases Updated HDPE Standard

In collaboration with more than 30 committee and subcommittee members, the American Water Works Association has updated its C901 Standard for PE4710 high-density polyethylene pressure pipe for use in potable water, reclaimed water and wastewater service lines.

ANSI/AWWA C901-25 Polyethylene Pressure Pipe, Tubing and Fittings, ¾ inches through 3 inches, for Water Service is now available.  Major changes include the addition of detailed requirements for fittings, including materials, workmanship, dimensions, tolerances, physical requirements, testing and marking.  More information can be found here.

The new standard also contains a descriptive statement about use of lead-free HDPE pipes and fittings and lead service line replacement: “HDPE pipes and fittings …are considered lead-free per U.S. Safe Drinking Water Act when certified to NSF/ANSI/ CAN 61, NSF/ANSI/CAN 372, or NSF/ANSI 14 [pw end use (for potable water)].  Existing LSL can be replaced with HDPE using open cut and a variety of trenchless installation methods.  Refer to ANSI/AWWA C810 for additional information.”
