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.
South Asia Rural Development Series. India's economic policies are aimed at increasing economic growth, improving market efficiency and competitiveness, and integrating the Indian economy with global markets. Much of the population and industrial growth is expected to occur in urban centers. Consequently, the demands on the Urban Water Supply and Sanitation sector (UWSS), will be great. Urban Water Supply and Sanitation states the UWSS sector needs urgent attention both to meet these new demands and to ensure that all city-dwellers have access to basic services at reasonable costs. This book outlines the way forward which includes a discussion on institutional reform and financial reform as well an action plan.
By analyzing water supply reforms in six developing country's capitals, this text provides a legal, economic and political examination of countries, tolerant of mismanagement of their water and sewerage systems for decades, that suddenly develop a thirst for efficiency.
Urban water security is crucial for achieving sustainable development, peace, and human health and well-being. Framing urban water security is challenging due to the complexity and uncertainty of its definition and assessment framework. Several studies have assessed water security in widely divergent ways by granting priority indicators equal weight without considering or adapting to local conditions. This dissertation develops a new urban water security definition and assessment framework applicable to water scarce cities, with a focus on Madaba, Jordan. It takes a novel and systematic approach to assessing urban water security and culminates in integrated urban water security index (IUWSI) as a diagnostic tool and guide management actions. The dissertation suggests a new working definition of urban water security based on the United Nations (UN) Sustainable Development Goal 6.1 on safe drinking water for all and the human rights on water and sanitation as follows: The dynamic capacity of water systems and stakeholders to safeguard sustainable and equitable access to water of adequate quantity and acceptable quality that is continuously, physically and legally available at an affordable cost for sustaining livelihoods, human well-being and socioeconomic development, ensuring protection against waterborne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability. This proposed definition captures issues at the urban level of technical, environmental and socioeconomic indicators that emphasize credibility, legitimacy and salience. The assessment framework establishes a criteria hierarchy, consisting of four main dimensions to achieve urban water security: drinking water and human well-being, ecosystem, climate change and water-related hazards and socioeconomic aspects (together, DECS). The framework enables the analysis of relationships and trade-offs between urbanization, water security and DECS indicators. The dissertation also provides a structured analysis to understand how urban water is managed in intermittent water supply system, by conducting a water balance analysis after quantifying the components of water losses in Madaba’s water distribution network. The findings showed that Madaba's non-revenue water (NRW) amounted to annual loss of about 3.5 million m3, corresponding to financial losses of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The dissertation provided an intervention strategy for strengthening infrastructure resilience and reducing leakage via the infrastructure, repair, economic, awareness and pressure (IREAP) framework. The IREAP framework provides a robust strategy to shift intermittent water supply (IWS) into continuous water supply. The IUWSI highlighted the state of water security in Madaba, Jordan and identified the means of implementation to move towards achieving urban water security based on the priorities for Madaba. The drinking water and human wellbeing dimension was the most important priority, receiving a weight of 66.22%, followed by ecosystem (17.15%), socioeconomic aspects (10.18%), and climate change and water-related hazards (6.45%) dimensions. The IUWSI indicated that the urban water security in Madaba is reasonable with a score of 2.5/5 and can meet the minimum requirements in several dimensions, but nonetheless, it has many loopholes to cover. Gaps are clear in the climate change and water-related hazards, and socioeconomic dimensions with scores of 1.6/5 and 2.237/5 respectively. Additionally, specific shortcomings are found in indicators such as water availability, reliability, diversity, and public health. The IUWSI framework assists with a rational and evidence-based decision-making process, which is important for enhancing water resource management in water-scarce cities
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.
Frontiers in Urban Water Management presents the state-of-the art in urban water management at the beginning of the 21st century. The book marks the end of the fifth phase of UNESCO's International Hydrological Programme in this field by bringing together major scientific and professional players to address critical and topical issues in water management. This team of leading world experts investigate themes such as the challenges of urban water management, infrastructure integration issues, and emerging paradigms in water supply and sanitation. Key issues are investigated from the hydrological, technical and managerial points of view, incorporating both social and economic realities. Specific reference is also made to solutions for developing countries. With a view to the future, conclusions from past experiences are highlighted, new pathways are explored and future developments are suggested. Contents The challenge of urban water management Urban water as a part of integrated catchment management Interactions with the environment Infrastructure integration issues Emerging paradigms in water supply and sanitation Problems of developing countries Economic and financial aspects Social, institutional and regulatory issues Outlook for the 21st Century
The aim of this book is to present the potential benefits as well as the challenges of introducing a more formal economic regulatory process into the urban water sector arena in lower-income countries. There is a particular focus upon the impact this may have on the poorest, the informal, slum and shanty dwellers of the rapidly growing cities. Economic regulation, usually introduced in the context of private operation of monopoly water supply, can deliver objectivity and transparency in the price-setting process for public as well as private providers. The book describes and analyses these issues through a consideration of ten country case studies. As a starting point, the current situation for the provision of water and sanitation services for the poorest through non-regulated public providers in India and Uganda is reviewed. Comparative chapters are then presented on Ghana, Philippines, Bolivia, Jordan, Zambia and Indonesia, all with varying degrees of private sector involvement and regulation. Finally the experiences of two richer countries are considered - Chile and England, countries with the longest experience of economic regulation and the 'most privatized' suppliers. In all cases there is a focus on the very necessary role of customer involvement in price-setting and service monitoring and on the role of alternative (private) service providers.
The Department for International Development DFID commissioned this Guidance Manual from the WELL Resource Centre to assist staff and partners to develop effective and sustainable water supply and sanitation programmes. It represents collaboration across a range of professions within the Department and from key UK professionals in the sector. It details inter-disciplinary approaches to planning and implementation of partnership-based programmes. The Manual comprises three chapters and appendices. These take the reader from an overview of the sector, through specific development perspectives, to detailed recommendations for each stage of the project cycle. Chapter 1 is an introduction to water supply and sanitation projects and sets the scene. It describes the WS&S sector with particular focus on the development of services for the poor in both urban and rural areas. Emphasis is placed on the importance of co-operation and partnership and the chapter also introduces the DFID programme and project process. Chapter 2 Principles and practice starts with an inter-disciplinary analysis of key issues and then sets out recommended approaches under seven perspectives: social development; health; environmental sustainability; economic and financial perspectives; institutional perspectives; technical aspects; and hygiene promotion and sanitation promotion. These are explored in some detail so that professional staff in DFID and its partners will gain a better understanding of all the aspects and not just their own speciality. Chapter 3 Water supply and sanitation in the DFID programme and project cycle is the 'how to' part of the manual which brings together the disciplinary perspectives at each stage of the project cycle. The key issues to be taken into account are set out in a helpful 'question and recommendation' format. Appendices include examples of logical frameworks for water supply and sanitation projects.
