Book Description
The primary purpose of this report is to provide information and to describe techniques that will help utilities and others determine the impacts of reduced demand on water utilities. The remainder of the report is organized as follows: Chapter 2, "Methods and Materials", describes the case-study format and the methodology used to collect the data; Chapter 3, "General Concepts," provides an overview of the significant economic and financial analysis concepts used to categorize and analyze the data; Chapter 4, "Profiles of Participating Agencies," describes the participating agencies, including general profiles of each; Chapter 5, "Operating Cost Impacts," details the analytical framework and results for short-term operating costs; Chapter 6, "Revenue Impacts," illustrates how water utility revenues and rates are affected by reduced demand and potential reactions to rate adjustments; Chapter 7, "Long-Term Capital Savings," describes potential savings from capital deferrals or avoidance resulting from demand reduction; Chapter 8, "External Impacts," provides an overview of the impacts that may occur outside of water utilities as the demand for water decreases; Chapter 9, "Conclusions," looks at all the impacts and how the results of this study can be used by utilities.

Book Description
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

Book Description
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.

Book Description
Managing Water Demand provides a comprehensive account of the tools used to manage water demand in the MENA region. The vast arid and semi-arid regions of the Middle East and North Africa region (MENA) constitute 85% of the region's land area and are home to approximately 60% of the region's population. Limited water resources pose severe constraints on people's economic and social progress, testing their resilience and threatening their livelihoods. Rainfall is not only scarce and unpredictable, but the region is also subject to frequent and severe droughts. Available surface water is declining and the over-pumping of groundwater beyond natural recharge rates is occurring, lowering the water table and causing an increase in groundwater salinity and ecological degradation. Water Demand Management (WDM) is about governance and tools that motivate people and their activities to regulate the amount and manner in which they access, use and dispose of water to alleviate pressure on freshwater supplies. It is also about protecting water quality. The development and promotion of such WDM practices, primarily for governments in the Middle East and North Africa (MENA) region, have constituted the core objectives supported by Canada's International Development Research Centre (IDRC) and its partners through the Water Demand Management Forums. Managing Water Demand provides a comprehensive account of the tools used to manage water demand in the MENA region. A critical review is presented of the efficacy of WDM techniques in the areas of wastewater reuse, water valuation, public-private partnerships and decentralization, and participatory irrigation management. This book will provide some of the necessary knowledge required to further promote WDM in the MENA region, while providing insight into the work required for much needed change to improve water governance.

Book Description
Many communities are facing water scarcity in developing and developed countries alike. There are numerous publications and on-going research studies documenting the changes in our climate and potential for worsening shortages in our future. Meeting future potable water demands as communities continue to grow will rely heavily on using our existing water resources more efficiently. Preparing Urban Water Use Efficiency Plans provides detailed approaches to developing and implementing a water conservation plan. This book covers the broad spectrum of conservation planning for urban communities including achieving more efficiency from: Residential domestic uses Commercial and governmental facilities use Industrial uses Pricing Water Loss Control Programs The steps in the Guide clearly outline and provide sample calculations to aid determining which water use efficiency activities are financially justifiable to undertake. The end result is a plan that policy decision makers can adopt and fund, and that water service provider staff can implement to help increase their community's water reliability. It includes numerous case studies and a Microsoft Excel based software tool to allow planners to evaluate the business case for implementing various water conservation activities. This book is an essential resource for professionals in water and wastewater resources, particularly for planners and engineers. It is also a useful guide for Post Graduate and Undergraduate students. Author(s): Lisa Maddaus, William Maddaus and Michelle Maddaus, Maddaus Water Management Inc.

Book Description
Improving the efficiency of water utilities and reducing water losses are becoming top priorities in Asia, with its often-limited water resources and rapidly increasing urban population. This publication provides an up-to-date introduction to the subject matter, highlights the complexity of managing non-revenue water (NRW), offers guidance on NRW assessment, and recommends appropriate performance indicators. It is, to a large extent, based on the work of the Water Loss Specialist Group of the International Water Association in the last decade, and is amply complemented by the authors' practical experiences in Asia and in other countries around the world.
