This article discusses the benefits of a flushing program to the water quality in a distribution system and compares and contrasts conventional flushing with unidirectional flushing. Also, several additional issues are discussed relating to water quality that include: coordinating unaffiliated groups when they perform activities affecting the distribution system such as the fire department and public works department; deteriorating water quality and biological growth in tanks or reservoirs where the level remains constant; maintaining water quality in systems with extensive uncoated iron pipe with effective corrosion control; and, reducing the number of artificial dead‐ends and minimizing the problems associated with broken valves during a flushing campaign with a regular valve exercise program.
