Book Description
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.

Book Description
Design of water distribution networks is traditionally based on trial-and-approach in which the designer assumes, based on experience and judgment, sizes of different elements and successively modifies them until a network with satisfactory hydraulic performance is obtained. This text covers: Essential hydraulic, economic optimization principles. Theory is developed gradually for optimal design of simple, single-source branched networks subjected to single loading to complex, multiple-source looped networks subjected to multiple loading. Strengthening and expansion of existing networks and also reliability-based design. Several illustrative examples enabling the reader to apply them in practice- approximately 100 line drawings.

Book Description
To keep drinking water safe involves more than following the letter of the law. This book introduces a comprehensive perspective and a proactive step-by-step approach to maintaining drinking water quality in distribution systems, and aids in delivering verifiably safe and economical water to end users. This second edition is updated throughout, and reflects the latest processes for improving drinking water quality in water systems and bringing those systems into compliance with the Lead and Copper Rule, the Disinfection By-Products Rule, and the Total Coliform Rule. It also presents the latest techniques for calming discolored water issues, keeping microbiological growth and biofilm formation in check, and preventing the formation of pinhole leaks in copper pipes. The book also aids in determining side effects of treatment chemicals, achieving simultaneous compliance with multiple regulations, and optimizing treatment chemical dosages.¿ A typical water distribution system is complex and chaotic with varying piping configurations, water flows, chemical reactions, and microbiological activity. It is, therefore, no surprise that monitoring and assessing water quality can be a daunting task. Water Distribution System Monitoring: A Practical Approach for Evaluating Drinking Water Quality simplifies this task by providing the tools for well-defined and measurable control of water quality.
