Book Synopsis Susceptibility of Distribution Systems to Negative Pressure Transients by : Kala K. Fleming
Download or read book Susceptibility of Distribution Systems to Negative Pressure Transients written by Kala K. Fleming and published by American Water Works Association. This book was released on 2006 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low or negative pressure transients (also called surge or water hammer) create temporary opportunities for external chemical and microbial contaminants at higher pressure to enter the water distribution system, creating potential health hazard and potential weakening of distribution pipes, leading to failure. This study investigates how such events as power outages, pump shutdowns, valve operations, main flushing, firefighting, and main breaks can create significant rapid, temporary drops in system pressure. The report offers useful recommendations for using surge models to optimally locate pressure monitors and to minimize the occurrence and impact from low- and negative-pressure transients.
Book Synopsis Predictive Models for Water Quality in Distribution Systems by : J. Clement
Download or read book Predictive Models for Water Quality in Distribution Systems written by J. Clement and published by American Water Works Association. This book was released on 2005-04-30 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two groups of specialists involved in the development and application of water quality models, each of which have a different perspective on the use of models: Academics and scientists - chemistry specialists and microbiologists who develop the models. Practitioners - modelers and distribution engineers who use them to solve problems. There are limitations and constraints in the characterization of the underlying processes and the practical application of models to distribution networks, which require further research. The objectives of the research were to characterize the current state of predictive distribution system water quality models and to identify critical research needs for their improvement. The project reviewed both the development and application of models. The report is intended to both steer future research and to act as a general reference on water quality modeling. The report combines a literature review with the practical experience of the project team. The content of a draft report was discussed at an international workshop attended by academics, engineers, scientists, and hydraulic modelers with the objective of agreeing on specific research needs necessary to improve predictive modeling for water quality in distribution systems. The conclusions of the report are derived from the workshop and form the basis of 11 specific research briefs that have been submitted to AwwaRF for consideration of funding. Researchers often focus on modeling the individual processes that control water quality rather than fully modeling water quality throughout distribution systems. For these "process models" to be applied to real distribution networks, they need to be extended to take in account the physical characteristics of the system?the special and temporal variations in flow, velocity and water age, and the effects of mixing water that has traveled along different flow paths.

Book Synopsis Drinking Water Distribution Systems by : National Research Council
Download or read book Drinking Water Distribution Systems written by National Research Council and published by National Academies Press. This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Application of HACCP for Distribution System Protection by : Kathy Martel
Download or read book Application of HACCP for Distribution System Protection written by Kathy Martel and published by American Water Works Association. This book was released on 2006 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
