Download or read book A Review and Evaluation of Reliability Concepts for Design of Water Distribution Systems written by Larry W. Mays and published by . This book was released on 1986 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study assembles information related to the applicability of mechanical reliability concepts to the evaluation of water distribution systems. Included in the report is a detailed review of water resources and reliability literature and development of a conceptual basis for a technique or methodology to apply reliability concepts to the design and evaluation of water distribution systems. A comprehensive review of the reliability literature indicates that even the term 'reliability' is ill defined when applied to the analysis of water distribution systems. The concept of availability proved to be a more valuable concept. Methods for quantifying availability of discrete water distribution system components are developed. Specific examples of pump station and pipe reliability analysis are presented. An extensive list of applicable references is included as Appendix A. Of primary interest to the designer of water distribution systems is the inventory of computer codes available for reliability analysis. (Author).

Download or read book Computer Modeling of Free Surface and Pressurized Flows written by M. Hanif Chaudhry and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers are widely used for the analysis, design, and operation of water resource projects. This gives accurate results, allowing the analysis of complex systems which may not have been possible otherwise, and the investigation and comparison of several different alternatives in a short time, thereby reducing the project costs, optimizing design, and efficient utilization of resources. This volume compiles an edited version of the lecture notes specially prepared by 14 well-known European and North American researchers. Part I deals with free-surface flows. Governing equations are derived and their solution by the finite-difference, finite-element, and boundary-integral methods are discussed. Then, turbulence models, three-dimensional models, dam-break flow models, sediment transport models, and flood routing models are presented. Part II is related to the modeling of steady and transient pressurized flows. Governing equations for both single and two-component flows are derived and numerical methods for their solution are presented. The modeling of water quality in pipe networks, of cooling water systems, and slow and rapid transients is then discussed.

Download or read book Pattern Recognition for Reliability Assessment of Water Distribution Networks written by N. Trifunovic and published by CRC Press. This book was released on 2012-02-13 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the patterns that describe reliability of water distribution networks focusing to the node connectivity, energy balance, and economics of construction, operation and maintenance. A number of measures to evaluate the network resilience has been developed and assessed to arrive at more accurate diagnostics of regular and irregular demand scenarios. These measures have been proposed as a part of the methodology for snap-shot assessment of network reliability based on its configuration and hydraulic performance. Practical outcome of the research is the decision support tool for reliability-based design of water distribution networks. This computer package named NEDRA (NEtwork Design and Reliability Assessment) consists of the modules for network generation, filtering, initialisation, optimisation, diagnostics and cost calculation, which can be used for sensitivity analyses of single network layout or assessments of multiple layouts. The study concludes that none of the analysed aspects develops clear singular patterns. Nevertheless, the proposed network buffer index (NBI) and the hydraulic reliability diagram (HRD) as visual representation of the network resilience give sufficient snap-shot pointing the composition of the index value, and displaying possible weak points in the network that can be hidden behind the averaged values of various reliability measures.

This book was released on 2006-12-22 with total page 404 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.

Download or read book Criteria for Valve Location and System Reliability written by Arun K. Deb and published by IWA Publishing. This book was released on 2007-07-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the lack of availability of proper tools for management of valves, it is very difficult for water utilities to supply water with minimum interruption in case of a water main break. Rules or guidelines for the placement of valves in the distribution system are not well defined, and the impact of valve placement rules on system reliability (i.e., minimizing out-of-service customers) has not been quantified in previous studies. The objectives of this research were to develop a rationale for valve location using design rules to optimize system reliability, to develop an easy to use program to analyze the efficiency of valves on the reliability of isolation of distribution networks, and to develop a computer model to analyze complicated networks and assist water utilities in minimizing interruption of supply in isolating water main breaks. The study provides analysis tools and rules for valve placement to allow water utilities to improve system reliability by reducing the number of customers affected by necessary water main isolations. The analysis tools can be used to identify critical valves and provide a quantitative basis for making cost-effective decisions about valve placement. The report includes a CD-ROM that contains the Strategic Valve Management Model (SVMM). The SVMM was developed to provide utilities with a better tool for valve maintenance and system expansion. The program is used to identify segments in water distribution systems and to simulate pipe and valve failure effects on the system.
