Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems -- consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances -- carry drinking water from a centralized treatment plant or well supplies to consumersa (TM) taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems.Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

The Water Science and Technology Board has released the first report of the Committee on PublicWater Supply Distribution Systems: Assessing and Reducing Risks, which is studying water quality issuesassociated with public water supply distribution systems and their potential risks to consumers. The distributionsystem, which is a critical component of every drinking water utility, constitutes a significant managementchallenge from both an operational and public health standpoint. This first report was requested by the EPA, asthe agency considers revisions to the Total Coliform Rule with potential new requirements for ensuring theintegrity of the distribution system. This first report identifies trends relevant to the deterioration of drinking waterquality in distribution systems and prioritizes issues of greatest concern according to high, medium, andlow priority categories. Of the issues presented in nine EPA white papers that were reviewed by the committee,cross connections and backflow, new or repaired water mains, and finished water storage facilities were judgedby the committee to be of the highest importance based on their associated potential health risks. In addition,the report noted that two other issues should also be accorded high priority: premise plumbing and distributionsystem operator training. This first report will be followed in about 18 months by a more comprehensive finalreport that evaluates approaches for risk characterization and identifies strategies that could be considered toreduce the risks posed by water-quality deteriorating events.
