Download or read book Water Demand Management written by David Butler and published by IWA Publishing. This book was released on 2005-12-01 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Assessment Framework for Urban Water Security written by Hassan Tolba Aboelnga and published by BoD – Books on Demand. This book was released on 2021-01-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Urban Water Security written by Robert C. Brears and published by John Wiley & Sons. This book was released on 2017-01-17 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Losses in Water Distribution Networks written by M. Farley and published by IWA Publishing. This book was released on 2003-03-31 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a best practice manual for addressing water losses in water distribution networks worldwide. Systems and methodologies are presented for improving water loss and leakage management in a range of networks, from systems with a well-developed infrastructure to those in developing countries where the network may need to be upgraded. The key feature of the manual is a diagnostic approach to develop a water loss strategy - using the appropriate tools to find the right solutions - which can be applied to any network. The methods of assessing the scale and volume of water loss are outlined, together with the procedures for setting up leakage monitoring and detection systems. As well as real losses (leakage) procedures for addressing apparent losses, by introducing regulatory and customer metering policies are explained. Suggestions are made for demand management and water conservation programmes, to complement the water loss strategy. Recommendations are made for training workshops and operation and maintenance programmes to ensure skills transfer and sustainability. The manual is illustrated throughout with case studies. Losses in Water Distribution Networks will appeal to a wide range of practitioners responsible for designing and managing a water loss strategy. These include consultants, operations managers, engineers, technicians and operational staff. It will also be a valuable reference for senior managers and decision makers, who may require an overview of the principles and procedures for controlling losses. The book will also be suitable as a source document for courses in Water Engineering, Resource Management and Environmental Management.

Download or read book Global Water Funding written by David Lloyd Owen and published by Springer Nature. This book was released on 2020-07-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is safe and sustainable water and sanitation for all an unaffordable pipedream? This book surveys the worldwide development of water and sewage services and the challenges in meeting Sustainable Development Goal 6 (SDG6) along with climate change, population growth and urbanisation. It explores the reasons why current SDG6 progress is failing, including weak policy implementation, staff shortages and inadequate funding, as well as the limited impact of aid funding. The author contends that despite a series of innovations, debt finance remains too small to address needs of developing economies. Therefore, instead of advocating new funding, this book proposes addressing the funding gap through technological innovation and more efficient management and procurement through a series of examples that have challenged traditional assumptions. After four decades of good intentions, SDG6 is making a difference in monitoring shortfalls for the first time, allowing for more effective responses. This book outlines the role of innovation in hardware development, procurement and installation, and discusses how network management and operations can most effectively address funding gaps. The potential for savings is considerable, if effectively replicated. New approaches are driving forward affordable resilience, including nature-based solutions such as upstream habitat enhancement to retain water and improve downstream water quality; the circular economy, including water, nutrient, energy and heat recovery from wastewater; and demand management. This book will be of great value to scholars, policy makers and practitioners interested in the global finance of sustainable water and sanitation.

Download or read book Urban Water II written by S. Mambretti and published by WIT Press. This book was released on 2014-05-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Water II is the proceedings of the 2nd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems. The meeting was reconvened following the success of the first conference held in the New Forest, home to the Wessex Institute of Technology in 2012. Water systems in the urban environment consist of supply networks as well as sewage and storm drainage systems. They interact with each other and with warm bodies such as rivers, lakes and aquifers, and this interaction affects the quality and quantity of the different systems. As our cities continue to expand, their urban infrastructure must be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanisation. New water systems are also required to reduce the risk associated with floods, network failures and many others related to inadequate networks. New systems should reduce economic losses and environmental impacts as well as promote a higher degree of reliability. Improved management, measurement and control mechanisms are needed to ensure the efficiency and safety of urban water systems. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Architects and town planners are also aware of the importance of the interaction between urban water cycles and city planning and landscaping. Management of all these aspects requires the development of specialised computer tools that can respond to the increased complexity of urban water systems. Relating to the subject areas of Water supply networks and Urban Drainage, topics covered include: Leakage and losses; Modelling and experimentation; Safety and security of water systems; Maintenance and repairs; Water quality; Water savings and reuse; Surface water and groundwater sources; Reservoirs; Network design; Waste water treatment and disposal; Structural works and infrastructure; Water quality issues; Combined sewer networks; Flood control; Storage tanks; Environmental impact; Domestic and industrial waste water issues.

Available in PDF, EPUB and Kindle. Book excerpt: Half of the world's people live in urban areas, and roughly a third of these live in desperate poverty without access to basic amenities. Taking on the themes of UN-HABITAT's Water and Sanitation in the World's Cities (2003), this new volume focuses on the deficiencies in the provision of water and sanitation where most of the populations of the developing world live: in towns and small cities. Drawing on extensive unpublished research and 15 commissioned papers from experts involved in designing and implementing innovative projects around the world, this is the first major study of the problems facing the smaller urban centres that are recognized to be of enormous importance by governments, international agencies, NGOs and service providers. Tackling these problems is a crucial part of development and of good governance, and critical to meeting the Millennium Development Goals. The volume will be essential reading for all professionals and researchers in the relevant fields and a valuable resource for teachers and students of urban development.
