This book addresses the technical, health, regulatory, and social aspects of ground water withdrawals, water use, and water quality in the metropolitan area of Mexico City, and makes recommendations to improve the balance of water supply, water demand, and water conservation. The study came about through a nongovernmental partnership between the U.S. National Academy of Sciences' National Research Council and the Mexican Academies of Science and Engineering. The book will contain a Spanish-language translation of the complete English text.
A common characteristic of water demand in urban areas worldwide is its inexorable rise over many years; continued growth is projected over coming decades. The chief influencing factors are population growth and migration, together with changes in lifestyle, demographic structure and the possible effects of climate change (the detailed implications of climate change are not yet clear, and anyway will depend on global location, but must at least increase the uncertainty in security of supply). This is compounded by rapid development, creeping urbanization and, in some places, rising standards of living. Meeting this increasing demand from existing resources is self-evidently an uphill struggle, particularly in water stressed/scarce regions in the developed and developing world alike. There are typically two potential responses: either "supply-side" (meeting demand with new resources) or "demand-side" (managing consumptive demand itself to postpone or avoid the need to develop new resources). There is considerable pressure from the general public, regulatory agencies, and some governments to minimise the impacts of new supply projects (e.g. building new reservoirs or inter-regional transfer schemes), implying the emphasis should be shifted towards managing water demand by best utilising the water that is already available. Water Demand Management has been prepared by the academic, government and industry network WATERSAVE. The concept of the book is to assemble a comprehensive picture of demand management topics ranging from technical to social and legal aspects, through expert critical literature reviews. The depth and breadth of coverage is a unique contribution to the field and the book will be an invaluable information source for practitioners and researchers, including water utility engineers/planners, environmental regulators, equipment and service providers, and postgraduates. Contents Water consumption trends and demand forecasting techniques The technology, design and utility of rainwater catchment systems Understanding greywater treatment Water conservation products Water conservation and sewerage systems An introduction to life cycle and rebound effects in water systems Developing a strategy for managing losses in water distribution networks Demand management in developing countries Drivers and barriers for water conservation and reuse in the UK The economics of water demand management Legislation and regulation mandating and influencing the efficient use of water in England and Wales Consumer reactions to water conservation policy instruments Decision support tools for water demand management
Aims to demonstrate why demand-side management is critical to urban water supply planning and to provide methods for incorporation. This book explains how and why urban water demands have changed over time and includes methods for the analysis of urban water demands. It also offers methods for integrating supply side and demand-side planning and management.
This book is the result of a joint research effort led by the U.S. National Academy of Sciences and involving the Royal Scientific Society of Jordan, the Israel Academy of Sciences and Humanities, and the Palestine Health Council. It discusses opportunities for enhancement of water supplies and avoidance of overexploitation of water resources in the Middle East. Based on the concept that ecosystem goods and services are essential to maintaining water quality and quantity, the book emphasizes conservation, improved use of current technologies, and water management approaches that are compatible with environmental quality.
This book describes challenges in the policy and practices of the various water sectors in the Philippines that have led to water conflicts. Such conflicts arise in the nature of rural-urban competition, trans-administrative boundary issues, and inconsistencies between customary and state rules, and even within state rules. Using inter-, multi- and trans-disciplinary approaches, and analysing from various scales - community, local and national governments - the book discusses policies and strategies needed towards achieving water security especially for the poor. Reflective of the complex and urgent water policy and governance issues in many developing countries, the book offers valuable lessons and insights to policy makers, water sector managers, planners and regulators as well as to academics, researchers and students.
The quality and availability of fresh water are of critical importance to human and ecosystem health. Given its central role in the functioning of all living systems, water is arguably the most important of all natural resources. Produced biennially, The World's Water provides a comprehensive examination of issues surrounding freshwater resources and their use. It offers analysis of the most significant trends worldwide along with the most current data available on a variety of water-related topics. This 2000-2001 edition features overview chapters on: water as a human right water and food desalination stocks and flows of fresh water international watersheds and water-related conflicts water reclamation/recycling the removal of dams It also includes brief reports on issues such as arsenic in ground water in Bangladesh, the collection of fog as a source of water in remote regions, the role of nongovernmental organizations in meeting basic water needs, and an update on water and the internet. Following the overview chapters are more than thirty charts and tables that offer data on topics including: water use by country, agricultural water use, salinization, endangered aquatic species, major rivers in China, dam capacity, desalination capacity, and more. The World's Water is the most comprehensive and up-to-date source of information and analysis on freshwater resources and the political, economic, scientific, and technological issues associated with them. It is an essential reference for water resource professionals in government agencies and nongovernmental organizations, researchers, students, and anyone concerned with water and its use.
Industry and commerce use vast amounts of water and in some parts of the world water is becoming a scarce commodity. We need to take more care in our future use of water, and this book is a 'best practice' manual for industrial and commercial users world-wide. It offers a practical account of the measures which can be taken to re-educate industrial and commercial users in the techniques of water saving and re-use anywhere in the world. The principles are covered in detail and supported by examples from specific industries and commercial operations. Author Mohan Seneviratne is Manager of Sydney Water's 'Every Drop Counts Business Program', which won the prestigious 2006 Stockholm Industry Water Award in recognition of how the utility is working in partnership with business, industry and government to help ensure the long-term sustainability of Sydney's water supply.* The first book to cover water conservation for industrial users from processing plants to pubs and clubs* Provides practical advice on implementing water conservation for users in various industry sectors* Written by a practicing water conservation consultant
This book is an outcome of the workshop on water demand forecasting in 1985. It summarises the 'state-of-the-art' in water demand forecasting, and identifies some of its links with environmental issues. The book discusses some of the issues raised in more detail and provides case studies.
Sustainable Water Resources Management presents the most current thinking on the environmental, social, and political dimensions of sustainably managing the water supply at local, regional, or basin levels.
