This book was released on 2019-07-12 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2019 in the subject Engineering - Mechanical Engineering, , language: English, abstract: The objective of this work is to simulate distribution network and to improve the efficiency of existing water distribution network to supplying potable water to end users. Network of the study area is simulated by EPANET data of topography of the study area is collected using land survey instrument per the known latitudes, longitudes for the study area. The scheme design is organized so that required output is attained by using available input parameters like population of the study area, rate of growth in population and elevation at required point to install service reservoir. Therefore, with all the available input parameters, now the network is run through EPANET software and the results are thoroughly checked with standards. At the final stage, the output results that are obtained after successful run from EPANET tool, they are cross checked thoroughly with standard required values. If any of the corresponding values are not within acceptable bounds, then the network is adjusted accordingly to the required input parameters and again the network will be examined in EPANET software. This procedure is repeated until the parameters like velocity, friction factor, water head, pressure head, diameter and friction factor values are in the precise range. Pressure head at all nodes in the study area are having appropriate pressure to extract water. Flow in all pipes or links are adequate enough to survive the pressures at nodes. Roughness coefficients of pipes are all quite adequate as the head loss due to friction is little. It is also proposed to install air valves at high elevations and sluice valves at low elevations. The practical applications like: plan and improve a system’s hydraulic performance, improve the quality of water distributed to consumers and study the disinfectant using based on water type.

Download or read book Losses in Water Distribution Networks written by M. Farley and published by IWA Publishing. This book was released on 2003-03-31 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a best practice manual for addressing water losses in water distribution networks worldwide. Systems and methodologies are presented for improving water loss and leakage management in a range of networks, from systems with a well-developed infrastructure to those in developing countries where the network may need to be upgraded. The key feature of the manual is a diagnostic approach to develop a water loss strategy - using the appropriate tools to find the right solutions - which can be applied to any network. The methods of assessing the scale and volume of water loss are outlined, together with the procedures for setting up leakage monitoring and detection systems. As well as real losses (leakage) procedures for addressing apparent losses, by introducing regulatory and customer metering policies are explained. Suggestions are made for demand management and water conservation programmes, to complement the water loss strategy. Recommendations are made for training workshops and operation and maintenance programmes to ensure skills transfer and sustainability. The manual is illustrated throughout with case studies. Losses in Water Distribution Networks will appeal to a wide range of practitioners responsible for designing and managing a water loss strategy. These include consultants, operations managers, engineers, technicians and operational staff. It will also be a valuable reference for senior managers and decision makers, who may require an overview of the principles and procedures for controlling losses. The book will also be suitable as a source document for courses in Water Engineering, Resource Management and Environmental Management.

Available in PDF, EPUB and Kindle. Book excerpt: The IWA Performance Indicator System for water services is now recognized as a worldwide reference. Since it first appearance in 2000, the system has been widely quoted, adapted and used in a large number of projects both for internal performance assessment and metric benchmarking. Water professionals have benefited from a coherent and flexible system, with precise and detailed definitions that in many cases have become a standard. The system has proven to be adaptable and it has been used in very different contexts for diverse purposes. The Performance Indicators System can be used in any organization regardless of its size, nature (public, private, etc.) or degree of complexity and development. The third edition of Performance Indicators for Water Supply Services represents a further improvement of the original manual. It contains a reviewed and consolidated version of the indicators, resulting from the real needs of water companies worldwide that were expressed during the extensive field testing of the original system. The indicators now properly cover bulk distribution and the needs of developing countries, and all definitions have been thoroughly revised. The confidence grading scheme has been simplified and the procedure to assess the results- uncertainty has been significantly enhanced. In addition to the updated contents of the original edition, a large part of the manual is now devoted to the practical application of the system. Complete with simplified step-by-step implementation procedures and case studies, the manual provides guidelines on how to adapt the IWA concepts and indicators to specific contexts and objectives. This new edition of Performance Indicators for Water Supply Services is an invaluable reference source for all those concerned with managing the performance of the water supply industry, including those in the water utilities as well as regulators, policy-makers and financial agencies.
Download or read book Drinking Water Distribution Systems written by National Research Council and published by National Academies Press. 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 Water Supply Network District Metering written by Armando Di Nardo and published by Springer Science & Business Media. This book was released on 2013-01-18 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of a water supply network can be substantially improved defining permanent sectors or districts that enhances simpler water loss detection and pressure management. However, the water network partitioning may compromise water system performance, since some pipes are usually closed to delimit districts in order not to have too many metering stations, to decrease costs and simplify water balance. This may reduce the reliability of the whole system and not guarantee the delivery of water at the different network nodes. In practical applications, the design of districts or sectors is generally based on empirical approaches or on limited field experiences. The book proposes a design support methodology, based on graph theory principles and tested on real case study. The described methodology can help water utilities, professionals and researchers to define the optimal districts or sectors of a water supply network.
