Focusing primarily on understanding the steady-state hydraulics that form the basis of hydraulic design and computer modelling applied in water distribution, Introduction to Urban Water Distribution elaborates the general principles and practices of water distribution in a straightforward way. The workshop problems and design exercise develop a temporal and spatial perception of the main hydraulic parameters in the system for given layout and demand scenarios. Furthermore, the book contains a detailed discussion of water demand, which is a fundamental element of any network analysis, and principles of network construction, operation, and maintenance. The attached CD contains all spreadsheet applications mentioned in the text, and the network model used in the design exercise. Written in a manner that is easily understood by those who know little about the subject, this introductory text will also benefit experts dealing with advanced problems who wish to refresh their knowledge.
We, the editors, have long believed that a strong knowledge of relatively simple economic and engineering concepts is valuable in solving water management problems. The lack of such knowledge has been apparent to us in some of the journal articles, research proposals and books we have reviewed. The articles which have been written concerning specific local water economies and management issues are scattered over a wide variety of journals, making them hard to access. Most of the extensive water resources literature is concerned with large regional water projects or with narrow technical and regional issues. This book was written to make practical economic and engineering concepts readily available to urban water supply managers, thereby filling a gap in the available literature. It is concerned with decisions made daily, monthly, or annually by managers of urban water supply systems. The book includes basic chapters presenting supply and cost concepts, calculation of demand elasticities, use of marketing concepts, public goods analysis, water markets, industrial water demand and the use of price in water conservation. The authors have included multiple examples of how these concepts can aid in managing urban water supply. The water provider is generally a governmental entity or regulated private utility. Most books on public utilities and their management emphasize gas, electricity, or telephone rather than water. Water is different because of m~or variations in quality by source and the necessity for proper disposal of waste water.
This book presents the advancements made in applied metrology in the field of Urban Drainage and Storm water Management over the past two decades in scientific research as well as in practical applications. Given the broadness of this subject (measuring principles, uncertainty in data, data validation, data storage and communication, design, maintenance and management of monitoring networks, technical details of sensor technology), the focus is on water quantity and a sound metrological basis. The book offers common ground for academics and practitioners when setting up monitoring projects in urban drainage and storm water management. This will enable an easier exchange of results so as to allow for a faster scientific progress in the field. A second, but equally important goal, is to allow practitioners access to scientific developments and gained experience when it comes to monitoring urban drainage and storm water systems. In-depth descriptions of international case studies covering all aspects discussed in the book are presented, along with self-training exercises and codes available for readers on a companion website.
This booklet is a supplement to the WHO monograph Tools for assessing the O&M status of water supply and sanitation in developing countries which comprises nine tools for measuring and evaluating the effectiveness of operations and maintenance (O&M) of water supply and sanitation services. The WHO tools are: Tool 1: Effectiveness of the O&M management system. Tool 2: Guidelines for an audit of O&M. Tool 3: A framework for assessing the status of O&M. Tool 4: Guidelines on O&M performance evaluation. Tool 5: Guidelines on O&M performance reporting. Tool 6: Guidelines for the selection of performance indicators. Tool 7: Performance indicators for water supply and sanitation. Tool 8: Potential information sources. Tool 9: Participatory information-gathering. Tool 7 suggests performance indicators which are specific to water supply and sanitation; all other tools are generic and apply equally to any other of the urban services. Tool 7A has been produced as a supplement to Tool 7 which provides some indicators in relation to these other urban services. On inspection of Tools 7 and 7A, however, it can be seen that it is relatively straightforward to develop equivalent performance indicators oneself for one's own use. An additional Tool 10 has also been prepared to offer advice on indicators for technical, financial and institutional sustainability.
Describes a systems approach to the operation and maintenance of drinking-water and sanitation services in urban areas of developing countries. Addressed to managers and other personnel with decision-making responsibilities, the book responds to ample evidence that poor management has had the greatest single negative impact on the quality of water supply and sanitation services. The guide, which is intended to serve as a reference source and conceptual framework, covers virtually all the procedures, activities, projects, and areas of managerial responsibility, at different levels, needed to ensure that water supply and sanitation services function continuously, efficiently, and to their full capacity. Emphasis is placed on procedures that can help control water losses. The book has five parts. The first describes the use of the management systems approach to analyse the functions of drinking-water and sanitation agencies and to solve operation and maintenance problems. Part two, on management, provides a step-by-step account of the key responsibilities and functions involved in managing an agency's operation and maintenance activities. The third and most extensive part serves as a detailed guide to the planning and control of operation and maintenance procedures. While most attention is given to projects for controlling water loss, part three also covers programmes for controlling the production and quality of drinking-water, and for sewage collection, treatment, re-use, and disposal. The remaining chapters describe information systems and the procedures and stages of implementation. Of particular practical value is a five-page tabular presentation of performance indicators that can be used to assess the effectiveness of specific activities.
This book is open access under a CC BY-NC 4.0 license. This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.
It is one of the series which presents the long term plans for Fiji, Papua New Guinea, Vanuatu and Solomon Islands particularly in urban areas.
This book is designed to assist those responsible for planning, implementing and supporting rural water supply prograames to increase sustainability.
The aim of this book is to provide a practical approach to a wide variety of water related topics. These explore the problems that arid and semi-arid countries face in relation to water resources and water management, using recent case studies as a result of recent and past experience to explore the possible solutions, as well to provide a framework/guideline to assist the practitioner in resolving these problems. The book contains case studies and practical guidelines developed from many years of project management, private sector participation and Ministerial level government appointment in both Water and Irrigated Agriculture. Many solutions were developed for specific problems/tasks, in particular, lessons learned from Management Contracts of water utilities.
