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.

This book was released on 2005-04-12 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Science and Technology Board has released the first report of the Committee on Public Water Supply Distribution Systems: Assessing and Reducing Risks, which is studying water quality issues associated with public water supply distribution systems and their potential risks to consumers. The distribution system, which is a critical component of every drinking water utility, constitutes a significant management challenge from both an operational and public health standpoint. This first report was requested by the EPA, as the agency considers revisions to the Total Coliform Rule with potential new requirements for ensuring the integrity of the distribution system. This first report identifies trends relevant to the deterioration of drinking water quality in distribution systems and prioritizes issues of greatest concern according to high, medium, and low priority categories. Of the issues presented in nine EPA white papers that were reviewed by the committee, cross connections and backflow, new or repaired water mains, and finished water storage facilities were judged by the committee to be of the highest importance based on their associated potential health risks. In addition, the report noted that two other issues should also be accorded high priority: premise plumbing and distribution system operator training. This first report will be followed in about 18 months by a more comprehensive final report that evaluates approaches for risk characterization and identifies strategies that could be considered to reduce the risks posed by water-quality deteriorating events.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Conveyance and Distribution of Water for Water Supply: Aqueducts, Pipe-Lines and Distributing Systems, a Practical Treatise for Water-Works Engineers and Superintendents During the past fifty years, great progress has been made in the construction and operation of water works. Large aqueducts and reservoirs have been built, the efficiency of pumping engines has been improved, and the purification of water has been greatly advanced. A number of good treatises on water supply have been published during recent years, but as they all endeavor to cover the whole subject, they necessarily fail to discuss some parts in sufficient detail to be of practical value to the water works engineer and superintendent. A complete treatise on water supply, including the collection and storage of water, its conveyance and distribution, pumping engines, water purification, and the maintenance and operation of water works, would require several volumes. Some of these subjects have already been fully discussed in separate treatises, but very little has thus far been published about the distribution of water, the detection and prevention of waste of water by means of Pitot tube gaugings and water meters; about fire protection, high-pressure water systems, tapping machines, valve-inserting machines, water stage recorders, and the many other devices and appurtenances with which the water works engineer and superintendent should be familiar. The author has endeavored to cover these subjects in the present volume. The facts given were obtained by practical experience, observation, study and correspondence during a service of over thirty years as one of the engineers of the water works of the City of New York; first, on the construction of the New Croton Aqueduct and Reservoirs, and later as consulting engineer of the Department of Water Supply, Gas and Electricity of said city, which has charge of the maintenance and operation of the City's water works. In discussing the various appurtenances and devices used on water works - such as gates, valves, hydrants, water meters, water-stage recorders, etc., - the author has described the leading types and makes. It is hoped that this feature, which makes the book somewhat encyclopedic, will save the water works engineer and superintendent much time and correspondence when he has occasion to consider the merits of different makes of appurtenances and devices.

Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue on Advances in Water Distribution Networks (WDNs) explores four important topics of research in the framework of WDNs, namely simulation and optimization modelling, topology and partitioning, water quality, and service effectiveness. With regard to the first topic, the following aspects are addressed: pressure-driven formulations, algorithms for the optimal location of control valves to minimize leakage, the benefits of water discharge prediction for the remote real time control of valves, and transients generated by pumps operating as turbines. In the context of the second topic, a topological taxonomy of WDNs is presented, and partitioning methods for the creation of district metered areas are compared. In relation to the third topic, the vulnerability to trihalomethane is assessed, and a statistical optimization model to minimize heavy metal releases is presented. Finally, the fourth topic focusses on the estimation of non-revenue water, including leakage and unauthorized consumption, and on the assessment of service under intermittent supply conditions.

Download or read book Society Water Technology written by Reinhard F. Hüttl and published by Springer. This book was released on 2015-11-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of the Interdisciplinary Research Group "Society – Water – Technology" of the Berlin-Brandenburg Academy of Sciences and Humanities. It describes interdisciplinary evaluation criteria for major water engineering projects (MWEPs) and portrays an application to the Lower Jordan Valley (Middle East) and the Fergana Valley (Central Asia). Both areas are characterised by transboundary conflicts, by challenges due to demographic and climate change and by political and societal pressures. Based on the findings, the book provides recommendations for science and political decisions makers as well as for international financing institutions. In addition, it outlines research gaps from an interdisciplinary perspective. In the past, MWEPs have been used as an instrument to cope with the demands of growing populations and to enhance development progress. Experiences with MWEPs have shown that a purely technical approach has not always brought about the desired results. In many cases, MWEPs have even resulted in negative implications for society and environment. Therefore, improved management strategies and enhanced technologies for a sustainable water resource management system are a prerequisite to meet present and future challenges. And, moreover, the continuous evaluation and optimisation of these measures is, likewise, a must.

Download or read book Crop Water Requirements written by J. Doorenbos and published by . This book was released on 1992 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is intended to provide guidance in determining crop water requirements and their application in planning, design and operation of irrigation projects; Part I.1 presents suggested methods to derive crop water requirements. The use of four well-known methods for determining such requirements is defined to obtain reference crop evapotranspiration (ETo), which denotes the level of evapotranspiration for different set of climatic data. To derive the evapotranspiration for a specific crop, relationships between crop evapotranspiration (ETcrop) and reference crop evapotranspiration (ETo) are given in Part I.2 for different crops, stages of growth, length of growing season and prevailing climatic conditions. The effect of local conditions on crop water requirements is given in Part I.3; this includes local variation in climate, advection, soil water availability and agronomic and irrigation methods and practices. Calculation procedures are presented together with examples. A detailed discussion on selection and calibration of the presented methodologies together with the data sources is given in Appendix II. A computer programme on applying the different methods is given in Appendix III. Part II discusses the application of crop water requirements data in irrigation project planning, design and operation. Part II. 1 deals with deriving the field water balance, which in turn forms the basis for predicting seasonal and peak irrigation supplies for general planning purposes. Attention is given to irrigation efficiency and water requirements for cultural practices and leaching of salts. In Part II. 2 methods are presented to arrived at field and scheme supply schedules with emphasis towards the field water balance and field irrigation management. Criteria are given for operating the canal system using different methods of water delivery, and for subsequent design parameters of the system. Suggestions are made in Part II. 3 on refinement of field and project supply schedules once the project is in operation. The presented guidelines are based on measured data and experience obtained covering a wide range of conditions. Local practical, technical, social and economic considerations will, however, affect the planning criteria selected. Therefore caution and a critical attitude should still be taken when applying the presented methodology.
