Water is vital to social and economic development whilst both arable land and water are scarce. Managing water is highly capital intensive, and capital is also scarce. Simultaneously, there are environmental consequences to any intervention in the water cycle whilst the economy depends on the environment. Therefore, for an integrated catchment, economic analyses must be undertaken on the analysis of the impacts of the proposed scheme upon the catchment as a whole.

This book starts with the Dublin declaration for defining sustainable water management and sets out the economic framework needed to support the implementation of its requirements. The book is divided into two parts: the theory and applications. The theory side sets out the nature of choice and decision-making, considering social and policy issues for water and resource management. The applications side provides the tools for the economic evaluation of water needs, the use of economic instruments and cost-benefit analysis.

This book provides a comprehensive examination of water resource management in the Omo-Turkana Basin, linking together biophysical, socioeconomic, policy, institutional and governance issues in a solutions-oriented manner. The Omo-Turkana Basin is one of the most important lake basins in Africa, and despite the likely transboundary impacts associated with the management of dams, it is the largest lake basin in Africa without a cooperative water agreement. This volume provides a foundation for integrated decision-making in the management of development in the Lake Turkana Basin. Chapters cover water-related conditions, hydropower, agriculture, ecosystems, resilience and transboundary governance. The final chapter proposes ways forward in light of the potential benefits that can be achieved through cooperation, and practical realities that cooperation is slow and may take time to achieve. This book will be of great interest to students and scholars of water and natural resource management, environmental policy, sustainable development and African studies. It will also be relevant to water management professionals.

This book has been written specifically for practitioners involved in the operation, maintenance and management of piped water distribution systems in urban areas of developing countries. These practitioners include engineers, planners, managers, and water professionals involved in the monitoring, control and rehabilitation of water distribution networks. The book explains in detail how to evaluate the risk of deterioration of the water distribution network of a water supply system. It begins with the conceptualization of risk evaluation and its three different components (hazard, vulnerability and risk). The book further elaborates on each of these three components, explains the methodologies used to estimate the components, and presents the background to the mathematical models. Finally, the book explains how these components are integrated to form a GIS-based decision support system for risk evaluation. The book is designed to help practitioners understand the concept of risk evaluation and supports the manual of the IRA-WDS software, a GIS-based decision support system for risk evaluation.

This book is the first of its kind on the emerging topic of source-to-sea management. It showcases different applications of the concept to improve the environmental health of freshwater, land and coastal and marine systems, drawing upon research performed across Europe, Africa and Asia. Improved management of land, freshwater, coasts and oceans is a key environmental challenge of our time. It is needed to prevent the millions of tons of plastic and other pollutants that enter the ocean from land-based sources each year. It is essential to reduce highly polluted, oxygen-depleted "dead zones" in our coastal and marine waters. Extensive diversions of the flows of rivers need to be avoided to ensure that little or no water reaches the sea. Source-to-sea (S2S) is an emerging concept to improve understanding of how to effectively manage freshwater, land, coastal and marine systems. The collected works in this book explore experiences with S2S management in diverse regions across Europe, Asia, Africa and Australia, addressing sedimentation, nutrient and pharmaceutical pollution in freshwater and marine aquatic environments, and marine debris on the coasts and in the seas. It provides key insights into a few areas that should be of interest to those who want to learn from the lessons from case studies of applied S2S interventions. This book will be of great value to scholars, students and researchers interested in global freshwater, coastal zone, ocean management, sustainable development and environmental governance. The chapters in this book were originally published as a special issue of the journal Water International.

"In many rural areas, groundwater is the only feasible way of providing safe, reliable water supplies. However, developing groundwater is not always straightforward. To meet the targets set out in the Millennium Development Goals, more attention needs to be paid to finding and developing groundwater in a sustainable, cost-effective and participatory manner. Developing Groundwater provides a user-friendly guide to this key topic, bringing together for the first time the wide range of techniques required to develop groundwater for community water supplies. This practical manual gives information on effective techniques for siting wells and boreholes, assessing the sustainability of sources, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors set the technical aspects of rural water supply firmly in their socio-economic context, so that readers can take proper account of community concerns as well as purely engineering questions. Packed with helpful illustrations this book is indispensable for all rural water supply project staff in developing countries. Alan MacDonald, Jeff Davies and John Chilton are hydrogeologists at the British Geological Survey with more than 75 years' experience amongst them. They have worked extensively in Africa, Asia and the Pacific in partnership with government departments, NGOs, research institutes and rural communities. Much of their work has focussed on the practical issues of developing groundwater resources for rural water supply. Roger Calow is a water resource economist and policy specialist with the British Geological Survey, and has worked extensively in Africa, Asia and the Middle East on rural water supply and management projects.

This book is divided into seven chapters, which address various leachate landfill management issues such as the quality, quantity and management of municipal landfill leachate, together with new methods. There are many methods available for the treatment and management of municipal landfill leachate. The waste management methods presented here can be applied in most third-world countries, due to the lack of waste separation and high organic content of waste. The book provides descriptions and a hierarchy of waste management, reviews the history of solid waste disposal, and covers a range of topics, including: leachate and gas generation in landfills; natural attenuation landfills; landfill site selection; leachate and stormwater management, collection and treatment; landfill gas management; landfill cover requirements; leachate collection; types of natural treatment systems; and design procedure and considerations. In closing, it provides an overview of the current solid waste management status in Iran.

Owing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling.

Management of Change in Water Companies tells real stories of real water companies that went through processes of change and achieved their best results ever in just a few years. It reflects the personal experience of the author from leading processes of change in five different water supply/sewage companies, between 10 and 120 years old and serving from 200,000 to 4,000,000 people. This practical and effective book shows: how to change, modernize and make profitable old-fashioned organizations, how to reduce water loss and promote efficiency in water companies, how to use the savings to rehabilitate and expand infrastructure without increasing tariffs, how to deal with overstaffing, how to plan, finance, build and maintain infrastructure, how to introduce innovation, how to motivate people, how to deal with clients, regulators, unions, shareholders, politicians and the press how to achieve sustainability. The case studies provide for instance, how to halve water losses in less than a year mostly with management measurements and very little investment, how to bring water losses from over 50% to below 20% in six years, how to use the savings from water loss reduction to build a new wastewater system without increasing tariffs, how to connect 100,000 existing buildings to a new sewage system in 4 years and how to get millions of people walking along the banks of rehabilitated urban creeks, rivers and beaches. The book presents case studies, management theory, comparative analysis of situations reported in the literature and the personal experience of an author who has lead a number of successful processes of change in different water companies. Management of Change in Water Companies is essential reading for water utility managers, national and local governments responsible for water policy as well as those concerned with the management of change and risk management. It is also useful to readers interested in the areas of pollution control, energy savings and water losses, and stream / beach / river restoration. Author: Joaquim Pocas Martins is Professor at the Faculty of Engineering of the University of Porto, Portugal, and provides excellent courses on the management of change in water companies world-wide.

On the one hand, population and economic growth are increasing the demand for water but on the other, environmental consequences of climate change, pollution and over extraction of groundwater are decreasing the worlds supply of fresh water. This makes the availability of water for human use one of the greatest global concerns of this century. Neither levelling growth nor technological innovation can stretch the existing supplies significantly; hence, it is imperative that demand side management techniques such as the use of water efficient fixtures in urban households, appropriate water tariff structure and regulatory policies are used as tools for water conservation. Conservation of water resources is one of the important aspects of ensuring sustainable development of cities and should incorporate environmental, social and economic dimensions. This book highlights the importance of using water efficiently in urban households, in both developed and developing cities. Specifically, the book focuses on: the determinants of water conservation behaviour, including psychological factors such as values, beliefs and attitudes, socio-economic factors such as income, water pricing and policies, environmental factors such as seasonal variations and demographic factors such as household size and age; the role of policies such as mandatory water restrictions, labelling of water saving devices and promotion of public awareness; the role of water and wastewater tariff structures in achieving the goals of revenue generation, affordability, demand management and equity and the design of conservation oriented rate structures; and the role of water saving devices in providing technological solutions to household water conservation. In relation to the above issues, the book provides several detailed case studies of cities to understand the effectiveness of such demand management tools and the lessons learnt. Overall, the book aims to provide a comprehensive overview of the various price and non-price tools that can be used to manage domestic water consumption. Water Conservation in Urban Households is a one-stop repository of information on water conservation for academics, practitioners and policy makers. The text can be used for teaching and research on water demand management as well as for professional reference by water utility officials. In addition, the appendix of the book contains a database of the current domestic water and wastewater tariffs and monthly bills of selected cities, which will be helpful for those willing to conduct research in this field.

This report provides a review of the literature on Cryptosporidium and helps to identify the findings and formulates the key research questions. It covers these central questions: What are the sources/carriers of human pathogenic strains and what are the key species for a range of catchments? What is the contribution of pre and post weaned cattle and sheep to catchment contamination? What data on animal management practices (including vegetation management of riparian zones) is available? What are the different climatic zones across catchments and how will this impact on the survival and transmission of Cryptosporidium? Co-published with WaterRA.

Climate change is reducing water resources in many parts of Australia. Increasingly, higher risk sources are either being developed or being considered for development as public drinking water sources. There is a rising demand from the community for additional recreation facilities and subsequent access to drinking water catchments, as they are predominantly close to urban areas. These competing factors place substantial pressure on public water utilities to ensure the provision of safe drinking water. As the health risk profile increases, there is a need for additional barriers which may include new or upgraded water treatment facilities. This report covers the methodological development in the WaterRA project Public Perception of Source Protection and Its Relationship to Recreation and Water Treatment. It aims to develop a nationally applicable methodology to assist in the formulation of defensible policy which provides for drinking water source protection while accounting for recreational needs in surface water catchments in Australia. This book is co-published with Water Research Australia.

N-nitrosodimethylamine (NDMA) is a nitrogen-containing organic compound that has known carcinogenic properties. NDMA has been a health concern for some industries for a number of years as it is used in rubber formulations, as a fire retardant, antioxidant, additive for lubricants and softener of copolymers; it is also a degradation product of dimethylhydrazine, an additive to rocket fuel. Most people are exposed to NDMA via a number of diverse routes including cigarette smoke (actively or passively) and processed foods, for example smoked meat products. However, it has only come to the attention of the international water industry since it was recognised as a disinfection by-product (DBP) of chloramination or chlorination in the presence of ammonia. The aim of this guidance manual is to answer commonly asked questions about this emerging issue, such as: How do they come to be in drinking water and recycled water and what * concentrations are "normal"? What regulatory/guidance levels have been imposed in Australia and elsewhere? How are they formed? What are the risk factors for the occurrence of nitrosamines in my system? What can we do to control them? What are the implications for the drinking and recycled water industry, and in particular for public health? This Guidance Manual has a companion document, Generic Management Plan for Nitrosamines in Drinking Water which provides provide background information on the group of organic contaminants, nitrosamines. This book is co-published with Water Research Australia.

Singapores journey during the past 45 years is an outstanding example that, in spite of multiple hardships, pragmatic policies, clear visions, long-term planning, forward-looking strategies and political will, as well as a relentless urge to improve, can result in strong foundations for sustainable development. This book describes the journey of Singapores development and the fundamental role that water has had in shaping it. What makes this case so unique is that the quest for self-sufficiency in terms of water availability in a fast-changing urban context has been crucial to the way development policies and agendas have been planned throughout the years. The authors analyse plans, policies, institutions, laws and regulations, water demand and water supply strategies, water quality and water conservation considerations, partnerships and importance of the media. They assess overall how all these issues have evolved in response to the dynamic needs of the city-state. The study of Singapore shows how a dynamic society can address development without losing its focus on the environment. In the city-state, environmental concerns in general, and water concerns in particular, have played a major role in its transformation from a third word to a first world country. How and why this transformation took place is the main focus of this authoritative book.

Metals are inorganic substances that occur naturally in geological formations. Naturally occurring metals are dissolved in water when it comes into contact with rock or soil material. Some metals are essential for life and are naturally available in our food and water. Trace amounts of metals are common in water, and these are normally not harmful to your health. In fact, some metals are essential to sustain life. Calcium, magnesium, potassium, and sodium must be present for normal body functions. Cobalt, copper, iron, manganese, molybdenum, selenium, and zinc are needed. However many of the metals and metalloids that are found in drinking water can have an adverse impact on human health. This book provides a state-of-the-art review of the health implications of metals and metalloids in drinking water and is a key reference in the risk assessment and management of water supplies. The increased urbanization and increased water demand in industrial areas has amplified the metals problem in groundwater sources. In fact the contamination of our water resources by poisonous metals occurs largely due to human activity.These activities include industrial processes, such as electronics industry and mining activity, agricultural activities, and the dumping of wastes in landfills. The International standard references concerning water resources are various and, though they are based on WHO guidelines, they are extremely diversified in relation to local issues and emerging problems. This report pulls the information together to provide an important reference source. This title belongs to Metals and Related Substances in Drinking Water: Research Report Series

The purpose of this book is to present an overview of the latest research, policy, practitioner, academic and international thinking on water security-an issue that, like water governance a few years ago, has developed much policy awareness and momentum with a wide range of stakeholders. As a concept it is open to multiple interpretations, and the authors here set out the various approaches to the topic from different perspectives. Key themes addressed include: Water security as a foreign policy issue The interconnected variables of water, food, and human security Dimensions other than military and international relations concerns around water security Water security theory and methods, tools and audits. The book is loosely based on a masters level degree plus a short professional course on water security both given at the University of East Anglia, delivered by international authorities on their subjects. It should serve as an introductory textbook as well as be of value to professionals, NGOs, and policy-makers.

The rapid development of nanoscience enables a technology revolution that will soon impact virtually every facet of the water sector. Yet, there is still too little understanding of what nanoscience and nanotechnology is, what can it do and whether to fear it or not, even among the educated public as well as scientists and engineers from other disciplines. Despite the numerous books and textbooks available on the subject, there is a gap in the literature that bridges the space between the synthesis (conventional and more greener methods) and use (applications in the drinking water production, wastewater treatment and environmental remediation fields) of nanotechnology on the one hand and its potential environmental implications (fate and transport of nanomaterials, toxicity, Life Cycle Assessments) on the other. Nanotechnology for Water and Wastewater Treatment explores these topics with a broad-based multidisciplinary scope and can be used by engineers and scientists outside the field and by students at both undergraduate and post graduate level.

The main objective of the research is the analysis of corruption in infrastructure delivery. This includes a review of accountability initiatives in infrastructure delivery and the nature of the impact of greater accountability.

A detailed view on the effects of seismic activity on tank structures As the use of aboveground and underground storage tanks (ASTs and USTs) continues to grow--with approximately 545 thousand in the US alone--the greatest threat to from AST and USTs is the contamination of groundwater, a vital source of drinking water throughout the world and one that close to half of Americans rely upon. These tanks suffer a great deal of strain during an earthquake, as a complicated pattern of stress affects them such that poorly designed tanks have leaked, buckled, or even collapsed during seismic events. Furthermore in oil and gas industrial plants, the risk of damage is even more critical due to the effect of explosion, collapse, and air or soil contamination by chemical fluid spillages. Seismic Design and Analysis of Tanks provides the first in-depth discussion of the principles and applications of shell structure design and earthquake engineering analyses focused on tank structures, and how these methodologies can help prevent the destruction of AST and USTs during earthquakes. Providing a thorough examination into the design, analysis, and performance of steel, reinforced concrete, and precast tanks, this book takes a look at tanks that are aboveground, underground, or elevated, anchored and unanchored, rigid or flexible, and evaluates the efficacy of each method during times of turbulence--and it does so without getting bogged down with impenetrable math and theory. Seismic Design and Analysis of Tanks readers will also find: Global approach for the best analytical and practical solutions available in each region: Discussion of the latest US codes and standards from the American Society of Civil Engineers (ACSE 7), American Concrete Institute (ACI 350,3, 371.R), American Water Works Association (AWWA D100, D110, D115), and the American Petroleum Institute (API 650) An overview of European codes and standards including Eurocode 8-4 and CEN-EN 14015 Hundreds of step-by-step equations accompanied by illustrations Photographs that feature real-world damage to tanks caused by seismic events Perfect for practicing structural engineers, geotechnical engineers, civil engineers, and engineers of all kinds who are responsible for the design, analysis, and performance of tanks and foundations--as well as students studying engineering--Seismic Design and Analysis of Tanks is a landmark text, the first work of its kind to deal with seismic engineering performance of storage tanks.

In an increasingly global community of researchers and practitioners, new technologies and communication means have made the transfer of policies from one country or region to another progressively more prevalent. There has been a lot of attention in the field of public administration paid to policy transfer and institutional transplantation. This book aims to create a better understanding of such transfers in the water management sector. These include the adoption of modern water management concepts, such as integrated water resources management and forms of water governance, which are strongly promoted and sometimes also imposed by various international organizations. Transfers also occur within the scope of development aid or for the purpose of creating business opportunities. In addition, many research organisations, consultancies and governmental agencies are involved in cross-border work. The purpose of this book is therefore to present practical examples of the transfer of modern water management from one locality to another and to critically discuss the transferability of policy and governance concepts by analysing the contextual needs and factors. Case studies are included from North America, Europe, the Middle East and Asia. It is argued that in many cases context matters in water management and that there is no panacea or universal concept that can be applied to all countries or regions with different political, economic, cultural and technological contexts. Yet it is also shown that some countries are facing pressing and similar water management issues that cut across national borders, and hence the transfer of knowledge may be beneficial.

The litany of alarming observations about water use and misuse is now familiar-over a billion people without access to safe drinking water; almost every major river dammed and diverted; increasing conflicts over the delivery of water in urban areas; continuing threats to water quality from agricultural inputs and industrial wastes; and the increasing variability of climate, including threats of severe droughts and flooding across locales and regions. These issues present tremendous challenges for water governance. This book focuses on three major concepts and approaches that have gained currency in policy and governance circles, both globally and regionally-scarcity and crisis, marketization and privatization, and participation. It provides a historical and contextual overview of each of these ideas as they have emerged in global and regional policy and governance circles and pairs these with in-depth case studies that examine manifestations and contestations of water governance internationally. The book interrogates ideas of water crisis and scarcity in the context of bio-physical, political, social and environmental landscapes to better understand how ideas and practices linked to scarcity and crisis take hold, and become entrenched in policy and practice. The book also investigates ideas of marketization and privatization, increasingly prominent features of water governance throughout the global South, with particular attention to the varied implementation and effects of these governance practices. The final section of the volume analyzes participatory water governance, querying the disconnects between global discourses and local realities, particularly as they intersect with the other themes of interest to the volume. Promoting a view of changing water governance that links across these themes and in relation to contemporary realities, the book is invaluable for students, researchers, advocates, and policy makers interested in water governance challenges facing the developing world.

In many respects, lead in drinking water has become a forgotten problem, since the mid 1980s when a range of environmental controls were implemented to reduce exposure to lead. This is largely because the sampling protocols, that underpin regulatory controls, are mostly inadequate and have tended to under-estimate the amount of lead that can be present in drinking water (IWA, 2010). Optimisation of Corrosion Control for Lead in Drinking Water Using Computational Modelling Techniques shows how compliance modelling has been used to very good effect in the optimisation of plumbosolvency control in the United Kingdom, particularly in the optimisation of orthophosphate dosing. Over 100 water supply systems have been modelled, involving 30% of the UK's water companies. This "proof-of-concept" project has the overall objective of demonstrating that these modelling techniques could also be applicable to the circumstances of Canada and the United States, via three case studies. This report is the first in the Research Report Series published by the IWA Specialist Group on Metals and Related Substances in Drinking Water. Authors: Dr. C. R. Hayes and Dr. T. N.
