Urban water conflicts manifested first in Europe in the 19th century and are observed nowadays in various forms throughout the world; in particular, in developing countries. Main causes of these conflicts are characterised by complex socioeconomic and institutional issues related to urban water management. The debate about public water services versus private water supplies is frequently associated with conflicts over water price and affordability. On the other hand, the issue of centralisation versus decentralisation of water utilities is also often discussed in the context of institutional aspects of urban water management. These issues are intertwined and, thereby, a critical examination of socioeconomic and institutional aspects of urban water management in a holistic way is important for better understanding water conflicts in urban areas. Urban Water Conflicts - the output of a project by UNESCO's International Hydrological Programme on "Socioeconomic and Institutional Aspects in Urban Water Management" - presents a collection of essays on socioeconomic and institutional aspects of urban water management, focusing on water and sanitation services. The book examines interdisciplinary approaches to understanding and analysing conflicts that arise from inadequate urban water management. Conflict analysis is addressed in some essays by taking into account economic, environmental and social dimensions of sustainability. The issue of institutional conflicts between different levels of government is also discussed in some case studies.

Urban Water Crisis and Management: Strategies for Sustainable Development, Sixth Edition presents solutions for the current challenges of urban water and management strategies. Through contributed chapters, a framework is laid out for a reduction of the use of groundwater (heavily overused as a solution) and the alternative options for the supply of water to cities, or for urban water. Sections discuss urban water, its problems and management approaches, address the root causes of the water crisis in urban areas, and cover the scientific and technical knowledge necessary to manage water resources. Significant gaps between developed and developing nations in the procedure of water management are also addressed, along with practical information regarding recycling and the reuse of wastewater which is useful as baseline data for the future. - Presents the quantitative study of water supply in urban areas, identifies water scarcity in megacities, and provides management approaches for sustainable development - Identifies technology and the instruments required for the management and safe supply of water - Includes case studies where these technologies have been successfully used

URBAN WATER INFRASTRUCTURE NATO ADVANCED RESEARCH WORKSHOP SUMMARY 22-27 JUNE 1989 KYLE E SCHILLING P E Workshop Director The Workshop was based on the recognition that all NATO countries are concerned with similar water infrastructure issues. Present problems are aggravated by aging and neglected facilities, by inadequate financing and by water management institutions reflecting the needs of an earlier era. Service needs to be provided for expanding populations, at the same time that corrective measures must be taken for decaying older urban centers, resulting both from neglect and expiring service life. These needs exist within the framewode of other competing and conflicting uses for existing and yet to be developed water sources. The problems have generated some highly visible national debates over financing due to the large sums involved. Despite differences in the age of the North American, European and other societies, the technological ages of water supply and storm water systems are much the same and provide a common denominator in the worldwide trend to urbanization. Examination of approaches to urban water management also indicates that they are generally based on past experience and institutions created in a non-urban era. The physical, financial and institutional alternatives are consequently often out-of-step with current urban environment. Historically, the supply of adequate water and efficient storm water management have also been top priority items with water quality and other aspects of environmental protection assuming a lower priority after basic supply needs have been met.

Ever increasing urbanization is impacting both the quantity and quality of urban water resources. These urban water resources and components of the water cycle are likely to be affected severely. To minimize the consequences on world water resources, the development of sustainable water resources management strategies is inevitable. An integrated urban water resources management strategy is the key to maintain sustainable water resources. A preliminary understanding of physio-chemical processes and analysis methodologies involved in each and every component of the urban water cycle is necessary. In the past these components have been investigated and published individually. With the view to aiding the development of integrated urban water resources management strategies, this book endeavors to present and explain the major urban water cycle components from a single holistic platform. The book presents the introduction, analysis and design methods of a wide range of urban water components i.e., rainfall, flood, drainage, water supply and waste water with the additions of sustainability practices in most of the components. Current "Hydrology" and "Hydraulics" books do not incorporate sustainability features and practices, while there are many books on general "Sustainability" without integrating sustainability concepts into typical engineering designs. The book starts with components and classifications of world water resources, then basic and detailed components of the hydrologic cycle, climate change and its impacts on hydrologic cycle, rainfall patterns and measurements, rainfall losses, derivations of design rainfalls, streamflow measurements, flood frequency analysis and probabilistic flood estimations, deterministic flood estimations, unit hydrograph, flood modelling, commercial modelling tools and use of Geographical Information System (GIS) for flood modelling, principles of open channel hydraulics, critical flow and flow classification indices, open channel flow profiles, uniform flow in open channel and open channel design, estimation of future population and domestic water demand, design of water supply systems, sustainable water supply system, water treatments, wastewater quantification, wastewater treatments, sustainable and decentralized wastewater treatment, stormwater drainage and urban drainage analysis, water footprint and water-energy nexus, features of water conservation, harvesting and recycling, components of sustainable urban design, stormwater treatment and integrated water management.

In the 21st Century, the world will see an unprecedented migration of people moving from rural to urban areas. With global demand for water projected to outstrip supply in the coming decades, cities will likely face water insecurity as a result of climate change and the various impacts of urbanisation. Traditionally, urban water managers have relied on large-scale, supply-side infrastructural projects to meet increased demands for water; however, these projects are environmentally, economically and politically costly. Urban Water Security argues that cities need to transition from supply-side to demand-side management to achieve urban water security. This book provides readers with a series of in-depth case studies of leading developed cities, of differing climates, incomes and lifestyles from around the world, that have used demand management tools to modify the attitudes and behaviour of water users in an attempt to achieve urban water security. Urban Water Security will be of particular interest to town and regional planners, water conservation managers and policymakers, international companies and organisations with large water footprints, environmental and water NGOs, researchers, graduate and undergraduate students.

Water is an essential element in the future of cities. It shapes cities’ locations, form, ecology, prosperity and health. The changing nature of urbanisation, climate change, water scarcity, environmental values, globalisation and social justice mean that the models of provision of water services and infrastructure that have dominated for the past two centuries are increasingly infeasible. Conventional arrangements for understanding and managing water in cities are being subverted by a range of natural, technological, political, economic and social changes. The prognosis for water in cities remains unclear, and multiple visions and discourses are emerging to fill the space left by the certainty of nineteenth century urban water planning and engineering. This book documents a sample of those different trajectories, in terms of water transformations, option, services and politics. Water is a key element shaping urban form, economies and lifestyles, part of the ongoing transformation of cities. Cities are faced with a range of technical and policy options for future water systems. Water is an essential urban service, but models of provision remain highly contested with different visions for ownership of infrastructure, the scale of provision, and the level of service demanded by users. Water is a contentious political issue in the future of cities, serving different urban interests as power and water seem to flow in the same direction. Cities in Africa, Asia, Australia, Europe and South America provide case studies and emerging water challenges and responses. Comparison across different contexts demonstrates how the particular and the universal intersect in complex ways to generate new trajectories for urban water.

Understanding the impacts of urbanization on the urban water cycle and managing the associated health risks demand adequate strategies and measures. Health risks associated with urban water systems and services include the microbiological and chemical contamination of urban waters and outbreak of water-borne diseases, mainly due to poor water and s

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.
