Description

AWWA Manual M14, Recommended Practice for Backflow Prevention and Cross-Connection Control, provides guidance to water purveyors on the recommended procedures and practices for operating a cross-connection control program. A cross-connection is an actual or potential connection between any part of a potable water system and any other environment that contains other substances that, under any circumstances, would allow such substances to enter the potable water system. The purpose of any cross-connection control program is to reduce the risk of contamination or pollution of the public water system.
