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.

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.

Following an active science-meets-industry approach on dealing with biomass and organics waste streams, this timely book foregrounds key issues facing South African policy makers, industry practitioners and scholars.

Spanning twelve chapters and divided into the following four key parts, the book offers solutions to industry and research on: Quantifying organic waste: An overview of potential sources and volumes is offered, with an identification and characterisation of solid biowaste residues. Biological treatment, covering the latest norms and standards; a biorefinery approach for the sugar industry; an integrated waste management approach for municipal sewage treatment; biogas production from abattoir waste; optimisation of biogas production from animal waste; and integrated bioremediation and beneficiation of bio-based waste. Mechanical and chemical treatment, covering the beneficiation of sawdust waste; developing sustainable biobased polymer and bio-nanocomposite materials; and the valorisation of waste mango seeds. Thermal treatment, which evaluates different municipal solid waste recycling targets in terms of energy recovery and CO2 reduction.

This book is designed to assist those involved in planning and implementing emergency sanitation programmes. The main focus of the book is a systematic and structured approach to assessment and programme design. It provides a balance between the hardware (technical) and software (socio-cultural, institutional) aspects of sanitation programmes, and links short-term emergency response to long-term sustainability. The book is relevant to a wide range of emergency situations, including both natural and conflict-induced disasters, and open and closed settings. It is suitable for field technicians, engineers and hygiene promoters, as well as staff at agency headquarters.

These guidelines are the result of two years collaborative research undertaken by WEDC with partners in Africa and South Asia. They demonstrate how water supply and sanitation projects in rural and peri-urban areas can be designed to meet user demand. The aim is to improve the use and sustainability of the services provided. The guidelines consist of three books: Book 1: Concept, Principles and Practice Book 2: Additional Notes for Policy Makers and Planners Book 3: Ensuring the Participation of the Poor.

Asia's 48 countries have an estimated 1.757 billion urban population and 2.4 billion people in rural areas (or approximately 60 per cent of the global population). Divided into central, eastern, southern, south-eastern and western regions, the continent is also extremely heterogeneous in terms of water quality conditions. The policies and management practices vary significantly from one country to another, and even within one country, depending on specific economic, political, social, environmental, legal and institutional factors. In order to appreciate the complexities associated with water quality policy and management, it is important to acknowledge the multiplicity of interrelated and often conflicting events, issues, actors and interests, both within and outside the water sector that impact them. This complexity, alongside institutional inability for systematic and coordinated collaboration, are potent reasons as to why, in the second decade of the 21st century, formulation and implementation of efficient water quality management policies benefitting humankind and the environment have still not been achieved. The book was originally published as a special issue of the International Journal of Water Resources Development.

Biofilms represent the natural living style of microbial communities and play a pivotal role in biogeochemical cycles and natural attenuation. Biofilms can be engineered for biodegradation and biotransformation of organic and inorganic contaminants, for both in situ bioremediation and ex situ treatment in bioreactors. This book focuses on microbial biofilms and their potential technological applications for sustainable development. It covers recent advances in biofilm technologies for contaminant remediation coupled to recovery of resources and serves as a complete reference on the science and technology behind biofilm mediated bioremediation and wastewater treatment.

Water Services Management and Governance focuses on water services (water supply, wastewater services) and deals with connections between water resources and services and water resources. It covers water supply mainly in urban communities, sanitation and pollution control and water resources and their linkages to water services. This book is divided in to four key sections relating to governance frameworks, technology and socio-ecological interactions, government and governance, and long terms policies. The chapters analyse the complexity of the water services sector based on a historical analysis of developments within the sector. The underlying conviction is that only by understanding past trends, processes and developments can the current situation in the water services be understood. Only through this understanding can policies for sustainable water services in the future be formulated. The four key sections relate to governance frameworks, technology and socio-ecological interactions, government and governance, and long terms policies. Water Services Management and Governance raises awareness that an understanding of the past is a necessity to explore potential, probable and preferable futures. It is an essential basis for water sector reforms in any country, region or community. The book is written for experts in water utilities, ministries, municipalities, NGOs, donor agencies, private companies and regulators; as well as students and researchers in water policy and governance, and the management of water resources, services and infrastructure.

REVIEWS "This welcome addition to the literature on water governance is a timely, thorough, and practical set of assessments of management challenges facing water service providers around the world. The diverse set of case studies, many of which focus on reforms to water supply provision, will be of interest to students and practitioners alike." KAREN BAKKER, Professor/Canada Research Chair, Director of the Program on Water Governance, The University of British Columbia "The anthology makes a very useful contribution to speed up the slow political awakening of reaching universal water services coverage: The lack of water services is in most cases not due to shortages of water, money and technologies, it is rather about poor governance. It provides many different insights from various cultural and political contexts and outlines and explains current changes in the governance architectures of water supply and sanitation." DR. HAKAN TROPP, Director, Water Governance Facility, Stockholm International Water Institute (SIWI)

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! This Code of Practice is concerned with metal pick-up by drinking water within the water supply chain, particularly from water mains and from domestic and institutional pipe-work systems. The principal metals of interest are copper, iron, and lead, and to a lesser extent nickel and zinc. The emphasis is on cold drinking water at its point of use by consumers. Metals arising from water sources and hot water systems are not considered. The intention is that this Code of Practice establishes an international standard for the control of internal corrosion of water supply systems. It provides a basis for identifying both problems and sustainable solutions in a manner which is sound scientifically and will help operators to achieve due diligence. It provides a template for improving internal corrosion control in countries, cities or towns where this has been neglected or poorly implemented. Internal Corrosion Control of Water Supply Systems is deliberately brief in its presentation of a wide array of complex information, in order to provide direction to practitioners that can be more easily related to their specific circumstances. The book also provides a series of check-lists and criteria to be used in risk assessment. Editor: Dr Colin R Hayes, University of Swansea, UK, Chair of IWA Specialist Group on Metals and Related Substances in Drinking Water.

Detection of Pathogens in Water Using Micro and Nano-Technology aims to promote the uptake of innovative micro and nano-technological approaches towards the development of an integrated, cost-effective nano-biological sensor useful for security and environmental assays. The book describes the concerted efforts of a large European research project and the achievements of additional leading research groups. The reported knowledge and expertise should support in the innovation and integration of often separated unitary processes. Sampling, cell lysis and DNA/RNA extraction, DNA hybridisation detection micro- and nanosensors, microfluidics, together also with computational modelling and risk assessment can be integrated in the framework of the current and evolving European regulations and needs. The development and uptake of molecular methods is revolutionizing the field of waterborne pathogens detection, commonly performed with time-consuming cultural methods. The molecular detection methods are enabling the development of integrated instruments based on biosensor that will ultimately automate the full pathway of the microbiological analysis of water.

This book examines the role of private firms in the American water and wastewater industry. As more water infrastructure shifts from public- to private-sector control, vendors, consultants, and facilities are taking on more importance. Lewis D. Solomon presents an historical overview of water supply and treatment needs and the role of the government, including how water policy has been crafted. He argues that water scarcity is becoming a problem due to groundwater depletion, contamination, and patterns of consumption. He examines the impact of climate change on water availability and quality considering voluntary conservation programs and mandatory restrictions for water use. Solomon points to how for-profit firms can use technology to increase water supply. He describes what privatization would look like in practice and reviews evidence from two case studies. Solomon proposes privatization as a viable response to America's water crisis that can address both scarcity and capital problems. "America's Water and Wastewater Crisis" presents a careful examination of how the water industry has operated in the United States in the past and how it may work as we move into the future. This book is invaluable to environmental specialists, businessmen, and government officials.

Access to water and sanitation service in industrialized countries is nearly taken for granted, but in many developing countries less than half of the population has access to such services. Decades of effort on a global scale have been invested to solve this problem. One such effort-Brazil's participatory approach to water and sanitation-is Nance's subject in Engineers and Communities. In the early 1980s, Brazilian engineers created participatory sanitation (known locally as condominial sewerage) to make basic sanitation service more inclusive. Fiercely contested at first, the technology's success hinged on the formation of strong and stable coalitions of diverse actors and on the promotion of both real participation and a participation narrative. The innovations described in the book contributed to the now indispensable concepts of community participation and locally appropriate technology. Today the technology has spread across Brazil- it has been legally incorporated into sewer design norms and codes, it is counted in the national census, and the model is being transferred to other countries by The World Bank and others who are trying to make basic urban services more inclusive of the poor. Engineers and Communities sheds light on what is essential in the broader discourse of international development.

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! The EU Drinking Water Directive sets a range of standards for metals and related substances in drinking water, many of which are concerned with health protection. A number of these standards are very stringent and require compliance to be assessed at the point of use. Because of the difficulties associated with monitoring, historic practices in many countries have concentrated on the quality of water within the distribution network. As a result, the magnitude of problems with some metals and related substances in drinking water is not fully appreciated in all European countries, and the extent and nature of corrective actions differ widely. This Best Practice Guide on Metals Removal From Drinking Water By Treatment describes drinking water standards and regulations, and explains the impact of a range of water treatment processes on metal levels in drinking water. Its objectives are to provide a basis for assessing the extent of problems and to identify appropriate water treatment options. The Guide provides a reasoned guide to selection of key water treatment processes. Each chapter focuses on a specific water treatment process and has been written by experts in that particular process. Best Practice Guide on Metals Removal From Drinking Water By Treatment provides practice-based knowledge for water engineers and scientists in large and small water utilities, regulatory agencies, health agencies and local municipalities (from cities through to small rural communities). It also supports university level teaching in degree schemes that relate to water management. This Guide is one of a series produced by the International Water Association's Specialist Group on Metals and Related Substances in Drinking Water. The series is an up-to-date compilation of a range of scientific, engineering, regulatory and operational issues concerned with the control and removal of metals from drinking water.

Part of Groundwater Set - Buy all six books and save over 30% on buying separately! Water Reclamation Technologies for Safe Managed Aquifer Recharge has been developed from the RECLAIM WATER project supported by the European Commission under Thematic Priority 'Global Change and Ecosystems' of the Sixth Framework Programme. Its strategic objective is to develop hazard mitigation technologies for water reclamation providing safe and cost effective routes for managed aquifer recharge. Different treatment applications in terms of behaviour of key microbial and chemical contaminants are assessed. Engineered as well as natural treatment trains are investigated to provide guidance for sustainable MAR schemes using alternative sources such as effluent and stormwater. The technologies considered are also well suited to the needs of developing countries, which have a growing need of supplementation of freshwater resources. A broad range of international full-scale case studies enables insights into long-term system behaviour, operational aspects, and fate of a comprehensive number of compounds and contaminants, especially organic micropollutants and bulk organics. Water Reclamation Technologies for Safe Managed Aquifer Recharge depicts advances in water reclamation technologies and aims to provide new process combinations to treat alternative water sources to appropriate water quality levels for sustainable aquifer recharge.

Disinfection By-Products and Human Health is based on contributions from speakers who participated in May 2011 workshops on Disinfection By-Products (DBPs) and Human Health at Ozwater 11 in Adelaide, Australia or at an AWA sponsored workshop at the Curtin Water Quality Research Centre, Perth, Australia. The contributions are prepared to facilitate communication with practitioners, rather than researchers, making use of overview illustrations rather than dense text or data tables. Each chapter concludes with up to 5 key findings that are take-home messages for practitioners. Disinfection By-Products and Human Health is aimed specifically at drinking water professionals (engineers, chemists and public health professionals) working on the front lines of drinking water issues where they must encounter actual day-to-day issues of risk management concerning DBPs in relation to all the other regulatory and water quality issues they must manage. Although a topic this complex is certainly not amenable to simplistic explanations, this book aims to provide drinking water professionals with a pragmatic assessment of the current evidence and emerging issues concerning DBPs and public health. Disinfection By-Products and Human Health is an essential, practical and accessible guide for drinking water professionals, engineers, chemists and public health professionals. Editors: Steve E.

Evolution of Water Supply Through the Millennia presents the major achievements in the scientific fields of water supply technologies and management throughout the millennia. It provides valuable insights into ancient water supply technologies with their apparent characteristics of durability, adaptability to the environment, and sustainability. A comparison of the water technological developments in several civilizations is undertaken. These technologies are the underpinning of modern achievements in water engineering and management practices. It is the best proof that "the past is the key for the future." Rapid technological progress in the twentieth century created a disregard for past water technologies that were considered to be far behind the present ones. There are a great deal of unresolved problems related to the management principles, such as the decentralization of the processes, the durability of the water projects, the cost effectiveness, and sustainability issues such as protection from floods and droughts. In the developing world, such problems were intensified to an unprecedented degree. Moreover, new problems have arisen such as the contamination of surface and groundwater. Naturally, intensification of unresolved problems led societies to revisit the past and to reinvestigate the successful past achievements. To their surprise, those who attempted this retrospect, based on archaeological, historical, and technical evidence were impressed by two things: the similarity of principles with present ones and the advanced level of water engineering and management practices. Evolution of Water Supply Through the Millennia is intended for engineers in water resources companies, hydraulic design companies, and water Institutes. It can be used for all courses related to water resources. Authors: Andreas N. Angelakis, Institute of Iraklion, National Foundation for Agricultural Research (N.AG.RE.F.), Greece, Larry W.

This book is about how water managers in the United States are responding to the call for increased effort to achieve sustainable supplies of clean fresh water for present and future generations. The author, himself a participant in the water supply chain, demonstrates that while water is indeed one of life's most essential commodities, in many parts of the United States it is one of the most stressed resources. Throughout the book the author illustrates both the good and the bad efforts taken or not taken by water and wastewater management with real life examples. This book will appeal to the educators, students, volunteers, elected officials, regulators, and other participants with a role in helping the suppliers of water and wastewater services to achieve their goals providing clean, safe water on a sustainable basis.

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! There is increasing concern regarding the presence of metals, particularly heavy metals in drinking water. In addition to the well-known toxic effects of lead, which are discussed at length in the Best Practice Guide on the Control of Lead in Drinking Water (in this series of Guides), the latest WHO guide values for maximum mean concentrations of arsenic, nickel and others in drinking water have been lowered compared to previous versions. European Union, USA and National standards for drinking water have followed the trend based largely on the same toxicological information. There is currently growing interest in the presence of hexavalent chromium in drinking water following its finding in some drinking waters in the USA above the national upper limit for total chromium and research suggesting that this limit needs to be considerably lowered. Some metals, particularly iron and manganese are associated with the production of discoloured (dirty) water in distribution systems and are therefore very important to the production of water with acceptable aesthetic qualities. Others (iron and aluminium) are key to the treatment of raw waters to drinking water standards. In most cases it is not possible to continuously monitor waters for metals and suitable sampling programmes must be designed and carried out to give results representative of the true water quality. The Best Practice Guide on Sampling and Monitoring of Metals in Drinking Water gives guidance on the design and quality control of sampling programmes for metals in Raw waters, in the water treatment works, in the drinking water distribution system and at the consumers tap. It also gives guidance on the analytical methods that can be used for the analysis of metals and quality control of those methods. Sampling programmes on the same water will vary according to the purpose for which they are carried out and the statistical techniques used to determine and design the different types of programme are outlined. Finally some case studies of optimisation of sampling are set out. Best Practice Guide on Sampling and Monitoring of Metals in Drinking Water is a valuable text for scientists, engineers and quality managers working in drinking water supply, laboratory managers and scientists who carry out sampling and analysis, and water industry consultants. It is also an excellent resource for post graduate and research workers in the field of drinking water. Editor: Dr Adam Postawa, AGH University, Krakow, Poland

Millions of slum residents across the world suffer the hazards and misery of frequent flooding of their streets and homes, which may result in the savings of a lifetime being washed away in a few hours, damaged property, loss of work and time, and higher risks of diarrhea, worm infection, and other health problems. This manual is written to help engineers, aid, and agency workers more clearly to understand drainage problems in the developing world, so that they can work towards finding practical solutions. It focuses on three questions of particular relevance to low-income urban areas in developing countries: What is drainage performance? How can we evaluate a drainage system to improve its performance? What are the effects of solids on the performance of drains? This manual is the outcome of two-and-a-half years of fieldwork in the city of Indore, in Madhya Pradesh, India and can be used as a practical aid by municipal engineers, consulting engineers, and engineering instructors and students, as well as development and aid workers involved in drainage systems.

All aspects of design and construction are covered including simple methods of sizing systems, erection of gutters, choice of materials, construction techniques, training, operation, and maintenance. Ina addition, non-technical factors such as water quality, health, social, financial, cultural, political, institutional, and general issues are discussed. The text is fully supported with drawings, photographs, and detailed step-by step accounts for several different types of household rainwater tanks. The material is based on practical experience learned over 20 years of constructing and researching rainwater systems in Africa and Asia. It will be of use and interest to project managers, development workers, water engineers, architects, builders, and researchers.

Accurate prediction of wastewater pipe structural and functional deterioration plays an essential role in the utility asset management process and capital investment planning. The key to implementing an asset management strategy is a comprehensive understanding and prediction of asset condition and performance. The primary objective of this research is therefore to develop protocols and methods for predicting the remaining economic life of wastewater pipe assets. The limits of deterioration prediction capabilities are not in mathematical models or statistical analysis methods, but in lack of accurate and consistent data. This report presented the short-term phase-1 which has been completed with results from intensive literature reviews, various interviews with utilities, and pipe associations. In this phase, the research team investigated the life cycle of wastewater pipeline and identified the causes of pipe failure in different phases including design, manufacture, construction, operation and maintenance, and repair/rehabilitation/replacement. The Research team has prepared various modes and mechanisms of pipe failure in wastewater infrastructure system as well as identified environmental and societal consequences of the failure. After reviewing all relevant reports and utility databases, the research team has developed a set of standard pipe parameter list (data structure) and pipe data collection methodology. The data structure has been classified into Gold, Silver, Bronze and Wood standard.

Innovative and Integrated Technologies for the Treatment of Industrial Wastewater deals with advanced technological solutions for the treatment of industrial wastewater such as aerobic granular biomass based systems, advanced oxidation processes integrated with biological treatments, membrane contactors and membrane chemical reactors. Wastewater from pharmaceutical, chemical and food industries as well as landfill leachates are specifically considered as representative of major problems encountered when treating industrial streams. The economic and environmental sustainability of the above solutions are also reported in the book and compared with the alternatives currently available in the market by life cycle assessment (LCA) and life cycle costing (LCC) methodologies. The implementation of the considered solutions at large scale could support and enhance the competitiveness of different industrial sectors, including the water technology sector, in the global market. Innovative and Integrated Technologies for the Treatment of Industrial Wastewater also makes a contribution towards defining: new concepts, processes and technologies in wastewater treatment with potential benefits for the stable quality of effluents, energy and operational costs saving, and the protection of the environment new sets of advanced standards for wastewater treatment new methodologies for the definition of wastewater treatment needs and framework conditions new information supporting development and implementation of water legislation.
