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 consumers' 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.

OBJECTIVES: The purpose of this project was to evaluate the application of the Hazard Analysis Critical Control Point (HACCP) system, a risk management tool, to better protect water quality in distribution systems. BACKGROUND: HACCP was first conceived in 1959 by the Pillsbury Company to improve food safety for NASA & rsquo;s manned space missions. Since the 1980s, HACCP has been widely adopted by the food and beverage industry worldwide, where it forms an important part of their food safety plans. Since the mid-1990s, HACCP has been applied by a number of individual drinking water systems and has been incorporated into many drinking water regulatory requirements and guidelines around the globe. HIGHLIGHTS: Project pilot studies illustrated that HACCP can be applied to water distribution systems, but time and resource requirements were greater than anticipated. Project case studies showed that most utilities that achieved HACCP certification had first implemented ISO 9001 and ISO 14001 or similar systems to gain management control of people and processes. The case study utilities operated one integrated management system including the ISO systems as well as HACCP to avoid duplication of tasks, reduce staff time and costs, and improve process integration. All case study utilities believed that, overall, the benefits of the HACCP system outweighed the costs.

Urban water services are building blocks for healthy cities, and they require complex and expensive infrastructure systems. Most of the infrastructure is out of sight and tends to be taken for granted, but an infrastructure financing crisis looms in the United States because the systems are aging and falling behind on maintenance.
