This standard describes shop-applied cement-mortar linings specified in the ANSI*/AWWA C100/A21 series of standards for ductile-iron pipe and ductile-iron and gray-iron fittings for potable water, raw water, wastewater, and reclaimed water systems and is intended to be used as a supplement to those standards.

Cement-mortar lined Ductile Iron Pipe provides a Hazen-Williams flow coeficient, or “C” value, of 140 — a realistic value that is maintained over the life of the pipe. This standard lining, which is furnished in accordance with ANSI/AWWA C104/A21.4, continues its tradition of dependable, trouble-free service.
