This is the second of two volumes that together provide a comprehensive overview of the current sustainable and low-cost wastewater treatment technologies applied in communities that lack the financial and technical resources needed for an environmental, disease prevention and health nexus. This book reviews engineered wastewater treatment technologies and discusses their application in regard to greenhouse gas emissions, natural resource utilization, land-use, and energy and water savings. The chapters from expert contributors cover topics such as aerobic and anaerobic biological treatments, chemical treatments and precipitation, and disinfection. Readers will also learn about simplified and low-energy wastewater treatment plants, strategies for wastewater reuse, and nanotechnologies for wastewater environmental management. The feasibility regarding time and cost of implementing such technologies is also discussed in this book, and particular attention is given to the removal of conventional and emerging pollutants, toxicants, and heavy metals. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

A new model for water management is emerging worldwide in response to water shortages, polluted waterways, climate change, and loss of biodiversity. Cities and towns are questioning the ecological and financial sustainability of big-pipe water, stormwater, and sewer systems and are searching for "lighter footprint" more sustainable solutions. Pilot projects are being built that use, treat, store, and reuse water locally and that build distributed designs into restorative hydrology. This book has been developed from the conference on Sustainable Water Infrastructure for Villages and Cities of the Future (SWIF2009) held in November 2009 in Beijing (China) that brought together an international gathering of experts in urban water and drainage infrastructure, landscape architecture, economics, environmental law, citizen participation, utility management, green building, and science and technology development. Water Infrastructure for Sustainable Communities China and the World reveals how imaginative concepts are being developed and implemented to ensure that cities, towns, and villages and their water resources can become ecologically sustainable and provide clean water. With both urban and rural waters as a focal point, the links between water quality and hydrology, landscape, and the broader concepts of green cities/villages and smart development are explored. The book focuses on decentralized concepts of potable water, stormwater, and wastewater management that would provide clean water. It results in water management systems that would be resilient to extreme events such as excessive flows due to extreme meteorological events, severe droughts, and deteriorated water and urban ecosystem quality. A particular emphasis is placed on learning lessons from the many innovative projects being designed in China and other initiatives around the world. The principal audience for the book is university faculty and students, scientists in research institutes, water professionals, governmental organizations, NGOs, urban landscape architects and planners.

Many EU cities are experiencing increasing problems with their water pipeline infrastructure. The cost of replacing these old, worn-out systems, if left to deteriorate beyond repair, is astronomical and clearly beyond the resources of many communities. Replacement, however, is not the only choice as many of these systems can be rehabilitated at 30 to 70 percent of the cost of replacement. Accordingly, resources are now increasingly being allocated to address pipeline rehabilitation management issues. Due to the emphasis on sustainable management, risk-based approaches for the rehabilitation management of the water supply network need to be developed. Rehabilitation decisions should be based, interalia, on inspection and evaluation of the pipeline conditions. Yet, utilities cannot locate a number of their old pipes and current inspection technologies typically do not provide the needed detailed information on pipeline damage. The objectives of this book are to describe the research work carried out in the framework of WATERPIPE project aiming: * To develop a novel, high-resolution imaging ground penetrating radar for the detection of pipes, leaks and damages and the imaging of the damaged region and evaluate it at a test site. * To produce an integrated system that will contain the equipment in "1" and a Decision-Support-System (DSS) for the rehabilitation management of the underground water pipelines that will use input from the inspections to assess, probabilistically, the time-dependent leakage and structural reliability of the pipelines and a risk-based methodology for rehabilitation decisions that considers the overall risk, including financial, social and environmental criteria. * To field test the equipment and the Decision-Support-System

This book, published in collaboration with ERSAR, presents a unique account of governance and regulatory methods used by different countries, states and municipalities that will help regulators and governments all over the world to improve their regulatory approaches. It is the first book to compile such an amount of data about regulatory processes of a wide number of countries from the five continents. It discusses how the characteristics of water and wastewater services call for regulation and how different countries apply distinct regulatory methods. By showing 18 country case-studies, the book offers an interesting perspective as the regulatory models adopted vary immensely depending on geographical location, nature and strength of institutions and governments, political ideology, features and level of development of the countries. In addition, it provides examples of best practices that may be important for policy-makers to enhance the regulatory processes adopted in each country. It looks closely at rules imposed by state and local governments concerning regulatory issues and how they are being applied. Regulation of Water and Wastewater Services covers the fundamental and practical concepts and issues regarding the regulation of water and wastewater services. It describes and compares the regulatory methods adopted in several countries and provides a global overview on regulation. There is detailed coverage of topics such as quality of service regulation, economic regulation and public service obligations. This book is suitable for regulators, academic researchers and students, consultants, operators and managers, policy-makers and other stakeholders.

International Trade in Water Rights provides a new approach to the questions raised by international water transfer projects: To whom does water belong? More precisely, what rules should govern international water transfers from transboundary watercourses? These issues are usually studied through the lenses of international trade law. International Trade in Water Rights offers a new approach by highlighting the fundamental issue of domestic and international water property regime and introducing the difference between trade in water and trade in water rights. International Trade in Water Rights analyses the conditions under which market-based instruments could participate in the resolution of water disputes over international watercourses and recommendations are made based on the study of two cases of inter-state water trading in the Colorado River Basin and in the Murray Darling Basin. It is argued that the recognition of water as an economic good in domestic water reform will increasingly impact the management of international watercourses. The book is of key interest to water professionals, economists, lawyers, and political scientists dealing with transboundary disputes over water.

It is predicted that climate change will result in big changes to the global distribution of rainfall, causing drought and desertification in some regions and floods in others. Already there are signs of such changes occurring, with particularly serious consequences for poorer countries. The need for international cooperation in managing the effects of climate change, and other influences on the hydrological cycle, is becoming urgent. Future wars may well be fought over water. This book is part of a series focusing on key issues in environmental science and technology. Focusing on the sustainability of water supplies to the growing populations throughout the world, this volume consists of articles contributed by a group of experts drawn from around the globe. Issues covered include: policy making in the European Union; rural water supplies in Africa; chemical monitoring and analytical methods; water use in agriculture; social justice in supplying water; potable water recycling, and sustainable water treatment. The book will be useful to those working in the water industry, policy makers and planners, researchers and environmental consultants, and students in environmental science, technology, engineering, and management. There is also much here to interest all concerned with major environmental issues such as climate change and the many other factors which influence the sustainability of water supplies.

The Gulf Coast hurricanes of 2005 and horrific events of 9/11/2001 have spawned a new emphasis on domestic security and emergency preparedness. Governments at all levels are taking action to reduce their vulnerabilities and prepare for emergencies, including unconventional disasters such as regional-scale weather events and terrorist attacks. A great deal has been written concerning security practices for large and medium-sized water and wastewater systems. Some of these practices are relevant and applicable to small, rural, and tribal wastewater systems, but many are not. Small systems tend to have characteristics which preclude them from adopting many of the practices employed by larger wastewater and water utilities. This report identifies security-related practices that are applicable for small wastewater systems. The report adopts a two-pronged approach with respect to security enhancement for small wastewater systems. First, the report focuses on security practices that are consistent with the technical, managerial, and financial capacity of small systems, and identifies a series of security-related "Practice Areas" that can be implemented in the near-term with modest expenditure of financial and/or staff resources. Second, the report outlines a strategy to help small utilities map-out programs for ongoing, sustainable security enhancement. This ongoing strategy is based primarily on the identification of practices and investments that a utility can pursue in cooperation with other municipal and regional entities.

Sewer systems constitute a very significant heritage in European cities. Their structural quality and functional efficiency are key parameters to guarantee the transfer of domestic and industrial wastewater to treatment plants without infiltration nor exfiltration. Infiltration of groundwater is particularly detrimental to treatment plant efficiency, while exfiltration of wastewater can lead to groundwater contamination. The European research project APUSS (Assessing infiltration and exfiltration on the Performance of Urban Sewer Systems) was devoted to sewer infiltration and exfiltration questions. It was structured in three main Work Areas dealing respectively with i) the development of new measurement methods based on tracer experiments and accounting for detailed uncertainty analyses, ii) the implementation of models and software tools to integrate structural and experimental data and to facilitate data display, operational management and decision-making processes and iii) the integration of economic and operational questions by means of cost estimation, economic evaluation, performance indicators and multi-criteria methods applied to investment/rehabilitation strategies. This final report describes the objectives, methods and main results for each Work Area. References to detailed methods, protocols, reports and tools are given in this final report which will be an invaluable source of information for all those concerned with the performance of urban sewer systems.

This authoritative reference work gives timely information on the global politics of water. Readers will find case studies on a variety of complex water situations, from the Okavango River that flows through Angola, Namibia and Botswana, to the Euphrates-Tigris of the Upper Persian Gulf.

• an A-Z glossary of key terms, issues, organizations, etc. in water politics
• information on selected major river basins of the world, including maps detailing water consumption and resources.

The Politics of Water is a useful guide to the politics surrounding the availability and provision of water on a world-wide scale. It will prove to be a useful reference source for anyone interested in, or studying, the politics of water and climate change.

The treadle irrigation pump is able to lift up to 7000 litres of water per hour using the power of the human body, and can be locally made at low cost in small-scale metalworking shops. Its acceptance in Bangladesh, where it was first developed in 1984, is extraordinary, with over 500,000 pumps estimated now to be in use.;The current design offered in this manual has evolved from the Bangladesh original into a fully portable pump with both lift and pressure capacity and is especially appropriate to situations where soils are permeable, and water cannot easily be distributed through channels. The manual is intended to be read primarily by organizations engaged in economic development activities which have a particular expertise in technology transfer; it is not intended just as a step-by-step guide for the manufacturer (although it can be used in this way).

This book is an unique integrated treatise, on the concepts of fractional calculus as models with applications in hydrology, soil science and geomechanics. The models are primarily fractional partial differential equations (fPDEs), and in limited cases, fractional differential equations (fDEs). It develops and applies relevant fPDEs and fDEs mainly to water flow and solute transport in porous media and overland, and in some cases, to concurrent flow and energy transfer. It is an integrated resource with theory and applications for those interested in hydrology, hydraulics and fluid mechanics. The self-contained book summaries the fundamentals for porous media and essential mathematics with extensive references supporting the development of the model and applications.

Covering such topics as designation of uses, antidegradation, procedures for review and revision of water quality standards, and the water-quality-based approach to pollution control, this handbook provides readers with guidance on complying with the Water Quality Standards Regulation, 40 CFR 131.

Infectious diseases caused by pathogenic bacteria, viruses and protozoa, are the most common and widespread health risk associated with drinking water. Most waterborne pathogens are introduced into drinking water supplies by human or animal faeces (enteric pathogens) but they can also exist naturally in water environments as indigenous aquatic micro-organisms. Controlling the risks related to these pathogens is a permanent challenge for the water industry. In addition to the constantly evolving range of pathogens to consider, assessing and managing such risks requires the integration of information issued by a wide range of disciplines. The necessary knowledge is however still sketchy and incomplete for most pathogens, and research efforts are necessary to fill the remaining gaps of knowledge. The purpose of this study is to provide an updated, comprehensive review of current knowledge on a selection of pathogens of interest for the drinking water industry, and to identify the remaining gaps of knowledge and thus the necessary research to be conducted. Emphasis has been laid on the information needed to assess and manage the risks related to each of these pathogens in drinking water production and distribution. The pathogens considered in this review were selected on the basis of: Their recognized or highly suspected transmission by drinking water through ingestion, inhalation, or contact Their recognized pathogenic character for humans The severity of their health effects Each micro-organism in this study is described in a summary fact sheet composed of the following items: microbiology, human health effects, geographical distribution, epidemiology, ecology, inactivation/removal, surrogates, environmental detection and research needs. Since much remains unknown about many aspects that are common to viruses, the study features a general section on virus research needs. A special section summarizes the risk management research conducted on waterborne pathogens. Finally, the conclusion gives an overview of the main gaps in current knowledge on waterborne pathogens.

Giving you the first comprehensive presentation of the ground breaking research undertaken at Heriot Watt University, with Research Council and industrial funding, this book brings a new perspective to the design of building drainage and vent systems. It provides the building services community with clear and verifiable design methods that will be robust enough to meet challenges such as climate change and water conservation; population migration to the mega cities of the developing world, and the consequent pressures of user concentration; the rise of the prestige building and the introduction of new appliances and control strategies. These all combine to make traditional codified design guidance insufficient. Many assumptions in existing codes defining the entrained airflows within building drainage vent systems cannot be theoretically supported, so designers concerned with these systems need analysis and simulation capabilities which are at least as reliable as those enjoyed by other building services practitioners.

The Method of Characteristics solution techniques which are well established in the pressure surge field are now used to provide solutions for drainage designers. The material is applied to a whole range of abstract scenarios then to a series of real world applications including the forensic modelling of the SARS virus spread within Amoy Gardens in 2003 and the refurbishment of the O2 Dome. Applications to specialised services, including underground station drainage and highly infectious disease treatment facilities are discussed and demonstrated, alongside the use of design and simulation techniques in support of product development.

Aimed at both professional and academic users, this book serves both as a design aid and as a core text for specialist masters courses in public health and building services engineering.

The module builds on the subjects of chemistry, biology and engineering covered in Process Science and Engineering for Water and Wastewater Treatment (Module 1) and provides a descriptive introduction to unit operations that are further described with design and operational details in later books in the series. The text of Principles of Water and Wastewater Treatment Processes has been divided into the following Units: Water Quality Process Flowsheeting Physical Processes Chemical Processes Sorption Processes Biological Processes Membrane Processes Sludge Treatment Utilisation Odour Management These units have has been designed for individual self-paced study that includes photographs, illustrations and tables and describe the form, function and application of unit operations for the treatment of water and wastewater. Each section of the text gives step-by-step learning in a particular subject, that includes an approximation of how long you will need to spend on that section and provides key points that highlight the principles of the different sections. Each unit includes exercises to help understand the material in the text, self-assessment questions to test your understanding and text references.

Water and Wastewater companies operating all around the world have faced rising asset management and replacement costs, often to levels that are financially unsustainable. Management of investment needs, while meeting regulatory and other goals, has required: A better understanding of what customers demand from the services they pay for, and the extent to which they are willing to pay for improvements or be compensated for a reduction in performance Development of models to predict asset failure and to identify and concentrate investment on critical assets Improved management systems Improved accounting for costs and benefits and their incorporation within an appropriate cost-benefit framework Incorporation of risk management techniques Utilisation of advanced maintenance techniques including new rehabilitation failure detection technologies Enhancements in pipeline materials, technologies and laying techniques. These papers developed from LESAM 2007 for inclusion in Strategic Asset Management of Water Supply and Wastewater Infrastructures are focused on the techniques, technologies and management approaches aiming at optimising the investment in infrastructure while achieving demanded customer service standards, and they provide an opportunity to gain access to the latest discussion and developments at the leading-edge in this field. This book will be essential reading for utility operators and managers, regulators and consultants.

Understand the effects of climate change on urban water and wastewater utilities with this collection of international scientific papers. Case studies and practical planning, mitigating and adapting information provided on greenhouse gases, energy use, and water supply and quality issues. This title is co-published with the American Water Works Association.

The literature review described in this report is part of a larger research project to assess STU performance with respect to treatment of important wastewater constituents. The overall goal of the project is to provide a toolkit and tool-use protocol that is easy to implement and available to a wide range of users to assess STU performance. This literature review is not a preview of tools that we will develop and propose, but rather an analysis of the information and data and the literature, to help guide our tool development. All tools developed will be based on rigorous experimental data and quantitative models verified with field data from operating systems. In some cases, more sophisticated tools (e.g., complex mathematical models) may be warranted depending on the relative complexity of the problem and the relative risk associated with a poor design. This literature review focused on STU performance, key conditions or factors potentially affecting STU performance, and the current best practices for using models and other available tools to predict expected STU performance. The information gained during this literature review will guide the future direction of the project. Constituents of interest include nitrogen (N), phosphorus (P), microbial pollutants, and emerging organic wastewater contaminants (OWCs). Based on this literature review, it is clear that due to the variability of data collected at field sites, simple binary relationships (e.g., C/Co versus depth for various soil types) for statistical predictions of the attenuation of N, P, microorganisms or OWCs cannot be justified. Specific to N, hydraulic loading rate appears to be more important than soil texture or soil depth within the first 30-60 cm, although both soil depth and texture remain important variables. Most of the reported results related to the interaction of P with soil appear to be from laboratory batch tests. Similarly, field-scale evaluations of pathogen removal are limited. Finally, most of the existing OWC work has focused on the occurrence and concentrations of selected compounds in streams, lakes, and groundwater impacted by wastewater treatment plant effluents. Currently very few models have been developed for movement and treatment processes of N or P in OWTS. However, adapting the CW2D model for STUs that will predict the effect of different soil types (texture, structure, and drainage class) appears promising. CW2D is a module of the well known HYDRUS model designed to simulate nitrogen treatment in a sand filter. This model incorporates most of the features one might consider, including a comprehensive treatment of microbial growth, the impact of oxygen mass transfer on nitrogen transformation, and variable rates of denitrification due to changes in dissolved oxygen concentrations, dissolved organic matter, and microbial growth. The review of existing models demonstrates that simulation of microbial characteristics in OWTS is still largely uncharted territory.

This book deals with a wide range of current development issues relating to subjects including community management, groundwater, health and disease, institutional development, irrigation, sanitation, solid waste management, water quality, water sources, water supply and water treatment. It presents over forty papers presented at the 19th WEDC Conference held in Accra, Ghana, in 1993. Material is drawn from countries in all parts of the world.

Combining background knowledge and practical tools, Handbook of Inland Aquatic Ecosystem Management gives you an overview of how to manage inland waters in a holistic manner. It examines the problems that threaten aquatic inland water ecosystems and presents a set of toolboxes for solving them. The book focuses on lakes, reservoirs, ponds, rivers, wetlands, lagoons, and estuaries, including the predominant freshwater ecosystems as well as saline and brackish ecosystems. Understand Ecosystem Properties and Ecological Processes The book consists of two parts. The first part reviews the basic scientific knowledge needed in the environmental and ecological management of aquatic ecosystems, from limnology and ecology of inland water ecosystems to environmental physics and chemistry. It emphasizes the interacting processes that characterize all inland aquatic ecosystems and explains the scientific considerations behind the conservation principles and their applications. Define the Problems and Quantify Their Sources The second part of the book presents toolboxes that you can apply to achieve more holistic environmental and ecological management. After an overview of the environmental problems of inland aquatic ecosystems and their sources, the book examines toolboxes to help you identify the problem, namely mass balances, ecological indicators, and ecological models. It also discusses toolboxes that can be used to find an environmental management solution to the problem: environmental technology, cleaner technology, and ecotechnology. Integrate Science and Practical Toolboxes to Manage Inland Waters More Effectively This book shows you how to integrate biology, ecology, limnology, and chemistry with the toolboxes in an up-to-date, multidisciplinary approach to environmental management. It provides a powerful framework for ident

Popular belief holds that throwing the contents of a chamber pot into the street was a common occurrence during the early modern period. This book challenges this deeply entrenched stereotypical image as the majority of urban inhabitants and their local governors alike valued clean outdoor public spaces, vesting interest in keeping the areas in which they lived and worked clean. Taking an extensive tour of over thirty towns and cities across early modern Britain, focusing on Edinburgh and York as in-depth case studies, this book sheds light on the complex relationship between how governors organised street cleaning, managed waste disposal and regulated the cleanliness of the outdoor environment, top-down, and how typical urban inhabitants self-regulated their neighbourhoods, bottom-up. The urban-rural manure trade, sanitation infrastructure, waste-disposal technology, plague epidemics, contemporary understandings of malodours and miasmatic disease transmission and urban agriculture are also analysed. This book will enable undergraduates, postgraduates and established academics to deepen their understanding of daily life and sensory experiences in the early modern British town. This innovative work will appeal to social, cultural and legal historians as well as researchers of history of medicine and public health.
