With increased commitment from the international community to reduce greenhouse gas (GHG) emissions from all sectors in accordance with the Paris Agreement, the water sector has never felt the pressure it is now under to transition to a low-carbon water management model. This requires reducing GHG emissions from grid-energy consumption (Scope 2 emissions), which is straightforward; however, it also requires reducing Scope 1 emissions, which include nitrous oxide and methane emissions, predominantly from wastewater handling and treatment. The pathways and factors leading to biological nitrous oxide and methane formation and emissions from wastewater are highly complex and site-specific. Good emission factors for estimating the Scope 1 emissions are lacking, water utilities have little experience in directly measuring these emissions, and the mathematical modelling of these emissions is challenging. Therefore, this book aims to help the water sector address the Scope 1 emissions by breaking down their pathways and influencing factors, and providing guidance on both the use of emission factors, and performing direct measurements of nitrous oxide and methane emissions from sewers and wastewater treatment plants. The book also dives into the mathematical modelling for predicting these emissions and provides guidance on the use of different mathematical models based upon your conditions, as well as an introduction to alternative modelling methods, including metabolic, data-driven, and AI methods. Finally, the book includes guidance on using the modelling tools for assessing different operating strategies and identifying promising mitigation actions. A must have book for anyone needing to understand, account for, and reduce water utility Scope 1 emissions.

Hydraulic Design and Management of Wastewater Transport Systems is a manual resulting from the research project CAPWAT (CAPacity loss in wasteWATer pressure pipelines), which researched the mechanisms for the creation, stagnation and discharge of gas bubbles in wastewater pressure pipelines. During this six-year research programme, it was recognised that there is no hydraulic manual/guideline that focuses on the entire wastewater pressure pipeline system, the processes it includes, and the interaction between the pressure pipeline and the pumping station. This manual provides a compilation of all the hydraulic knowledge that is necessary for designing a wastewater transport system and to manage it operationally. The wastewater transport system is the link between the collection and treatment of the wastewater and the collection system includes, among others, the gravity flow sewage system from the house (or consumer) and service connection through street and main sewers up to the suction basins. The transport system, for which this manual was written, includes the suction basin, the sewage pumping station and the pressure pipelines. Wastewater transport systems are becoming more complex due to building larger sewage water treatment plants, wastewater being transported over greater distances and increasingly more (and smaller) pipelines connecting to the main sewers. The operation of the pumping stations is largely determined by how the entire system behaves. Insight into this operation is, therefore, crucial for proper design and management. The central point of the design is to create an independent and safe system with the necessary transport capacity at minimum societal costs. Predominantly, the management aspect focuses on guidelines to maintain the design principles regarding capacity and required energy.

Most People in rural Africa do not have access to safe toilets and their health and well-being suffers as a consequence. There is an urgent need for the construction of simple, low-cost, affordable toilets that are easy to build and maintain. Toilets that make compost provides practical examples of toilets that, in addition to providing a safe sanitation option, also recycle the nutrients in excreta to produce compost. This compost is valued wherever wherever households have enough space to grow fruit and vegetables in their back gardens; the designs are suitable for regions where there is no high water table or prolonged wet season. This book provides detailed instructions for constructing a range of toilets from the simplest and most affordable to the more sophisticated ecological toilet.

Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated this new edition has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. New topics in this new edition include : * activated sludge bulking and foaming control and enhanced bioflocculation; * algae removal and harvesting; * dissolved organic nitrogen (DON) removal; * inorganics removal; * turbidity and its measurement; * wastewater treatment by coagulation and chemically enhanced primary treatment (CEPT). The book presents the subject logically and sequentially from theoretical principles to practical applications. Successive chapters deal with, in turn, properties of materials present in waters and wastewaters; characteristics and types of coagulants commonly in use; mechanisms and practical implications of destabilization of waterborne material using metal coagulants and polyelectrolytes; considerations and requirements for coagulant addition at the rapid mixing stage; theoretical and practical considerations of flocculation; and details of experimental procedures for assessing primary coagulants, flocculant aids, sludge conditioners, and flocculation parameters. Numerous examples are included as appropriate. Treatment and disposal of sludges resulting from coagulation-flocculation related operations is dealt with in an Appendix. This important topic has been separated from the main text to avoid disturbing the continuum of the presentation. Coagulation and Flocculation in Water and Wastewater Treatment is a readable and useful resource for the water scientist and engineer. It is a convenient reference handbook providing numerous examples and appended information and it is a vital text for course material for undergraduate and postgraduate students.

India is facing a river pollution crisis today. The origins of this crisis are commonly traced back to post-Independence economic development and urbanisation. This book, in contrast, shows that some important early roots of India's river pollution problem, and in particular the pollution of the Ganges, lie with British colonial policies on wastewater disposal during the late 19th and early 20th centuries. Analysing the two cornerstones of colonial river pollution history during the late 19th and early 20th centuries - the introduction of sewerage systems and the introduction of biological sewage treatment technologies in cities along the Ganges - the author examines different controversies around the proposed and actual discharge of untreated/treated sewage into the Ganges, which involved officials on different administrative levels as well as the Indian public. The analysis shows that the colonial state essentially ignored the problematic aspects of sewage disposal into rivers, which were clearly evident from European experience. Guided by colonial ideology and fiscal policy, colonial officials supported the introduction of the cheapest available sewerage technologies, which were technologies causing extensive pollution. Thus, policies on sewage disposal into the Ganges and other Indian rivers took on a definite shape around the turn of the 20th century, and acquired certain enduring features that were to exert great negative influence on the future development of river pollution in India. A well-researched study on colonial river pollution history, this book presents an innovative contribution to South Asian environmental history. It is of interest to scholars working on colonial, South Asian and environmental history, and the colonial history of public health, science and technology.

Urban sanitation and solid waste sectors are under significant pressure in East Africa due to the lack of competent institutional capacity and the growth of the region's urban population. This book presents and applies an original analytical approach to assess the existing socio-technical mixtures of waste and sanitation systems and to ensure wider access, increase flexibility and ecological sustainability. It shows how the problem is not the current diversity in waste and sanitation infrastructures and services and variety of types and scales of technology, of formal and informal sector involvement, and of management and ownership modes. The book focuses instead on the lack of an integrative approach to managing and upgrading of the various waste and sanitation configurations and services so as to ensure wider access, flexibility and sustainability for the low income populations who happen to be the main stakeholders. This approach, coined "Modernized Mixtures", serves as a nexus throughout the book. The empirical core addresses the waste and sanitation challenges and debates at each scale - from the micro-level (households) to the macro-level (international support) - and is based on the results of a five-year-long interdisciplinary, empirical research program. It assesses the socio-technical diversity in waste and sanitation and provides viable solutions to sanitation and waste management in East Africa. This book provides students, researchers and professional in environmental technology, sociology, management and urban planning with an integrated analytical perspective on centralized and decentralized waste and sanitation configurations and tools for improvement in the technology, policy and management of sanitation and solid waste sectors.

Produced as part of WEDC's contribution to the International Year of Sanitation 2008, this book provides easy-to-use tools for assessing sanitation, water supply and hygiene facilities in primary schools in Africa sothat appropriate decisions can be made about sanitation improvements. It also presents guidelines for rehabilitating or decommissioning existing latrines; for choosing the right type of latrine where new facilities are requires; for siting latrines appropriately within a school compound; and for the operation and maintenance of these facilities. A number of low-cost toilet designssuitable for many rural and peri-rural locations in Africa are also included. Written in a readable style and copiously illustrated, the book has been designed primarily for school managers and headteachers but it will also be of interest to planners, architects and engineers.

Falling or stagnant agricultural growth, increasing dependence on groundwater, climate variability, swift industrialization, and unplanned and unregulated urbanization in South Asia have spawned a variety of challenges for water resources governance, management and use: groundwater overdraft; insufficient, ill-managed and poor-quality freshwater supply vis-a-vis escalating demand; and water pollution. Water policies in each of the South Asian countries thus call for a more holistic understanding for the efficient management, equitable distribution and sustainable use of this scarce resource. Analyzing the economic, demographic and ideological context in which water policies are framed and implemented, this book argues for an integrated framework in formulating and implementing water policies in South Asia. It also highlights some common missing links in the national policies: problems of techno-centric and blueprint approach to water management, growing influence of international donor agencies and inadequate concern for issues such as equity, sustainability, gender sensitivity, accountability, regional diversity in property rights regimes and water management practices, and regional conflicts over water access. The innovative and nuanced knowledge on water resources produced from detailed case studies in India, Bangladesh, Bhutan, Nepal, Pakistan and Sri Lanka will be useful for professionals, academics, policymakers and activists as well as those in development studies, environmental studies, natural resource management and public administration.

In the summer of 1999, an international group of experts convened in Jerusalem, Israel, in order to define the major environmental challenges facing humanity at the dawn of the new millennium and - where possible - propose ways of addressing them. Almost 50 selected articles are collected in the present book, which constitutes a striking interdisciplinary combination of state-of-the-art science with the latest views on environmental law, education, and international cooperation. Whilst a major fraction of the book is devoted to water-related issues (water quality monitoring, water and wastewater treatment, water-based international cooperation, and more), other sections deal with timely topics relating to air pollution, biodiversity, conservation, and education. The book is intended for environmental scientists, professionals, and students of all disciplines.

The Inter-American Development Bank (IDB), in cooperation with the International Water Association (IWA), has developed a rating system that assesses the performance of water and sanitation service providers in a comprehensive way. AquaRating: An international standard for assessing water and wastewater services aims to provide an industry standard for utilities. The innovative rating system seeks the improvement of the service delivered by means of a rigorous and systematic assessment. AquaRating comprises more than 100 assessment elements organized in eight rating areas: Service Quality, Efficiency in the Planning and Execution of Investments, Operating Efficiency, Business Management Efficiency, Financial Sustainability, Access to Service, Corporate Governance, Environmental Sustainability. Each of the assessment elements and consecutively rating areas is assigned a rating (from 0 to 100), which in turn are aggregated into a single rating for the utility. Assessment elements consist of qualitative good practices and quantitative indicators. The total compliance with practices and achievement of the most demanding indicators levels means delivery of an excellent service and, therefore, awards a maximum rating of 100 points. AquaRating takes into account the quality of the information supporting the ratings results by correcting the rating for the reliability level of such information. The rating results are certifiable thanks to an independent audit of the supporting information. The expected benefits of the system are manifold: * Utilities - Identify areas of improvement, receive guidance and monitor progress over time. - Obtain an external and credible performance rating, which contributes to foster reputation, accountability and acceptance by key stakeholders, gain access to new markets and finance, and attract qualified staff. - Get access to a knowledge and assessment framework that fosters continuous learning. * Governments, regulators and development agencies - Use the system to stimulate utilities to maintain or improve their performance and to target technical assistance and finance according to the specific opportunities for improvement identified. * Consumers - Obtain better services in terms of access, quality, efficiency, sustainability and transparency.

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.

Early applications of desalination were small-scale plants deploying a range of technologies. However with the technological developments in Reverse Osmosis, most new plants use this technology because it has a proven history of use and low energy and capital costs compared with other available desalination technologies. This has led to the recent trend for larger seawater desalination plants in an effort to further reduce costs, and 1000 MLD seawater desalination plants are projected by 2020. Efficient Desalination by Reverse Osmosis recognises that desalination by reverse osmosis has progressed significantly over the last decades and provides an up to date review of the state of the art for the reverse osmosis process. It covers issues that arise from desalination operations, environmental issues and ideas for research that will bring further improvements in this technology. Efficient Desalination by Reverse Osmosis provides a complete guide to best practice from pre-treatment through to project delivery. Editors: Stewart Burn, Visiting Scientist, CSIRO Manufacturing.

An international river basin is an ecological system, an economic thoroughfare, a geographical area, a font of life and livelihoods, a geopolitical network and, often, a cultural icon. It is also a socio-legal phenomenon. This book is the first detailed study of an international river basin from a socio-legal perspective. The Mekong River Basin, which sustains approximately 70 million people across Cambodia, China, Laos, Myanmar, Thailand and Vietnam, provides a prime example of the socio-legal complexities of governing a transboundary river and its tributaries. The book applies its socio-legal analysis to bring a fresh approach to understanding conflicts surrounding water governance in the Mekong River Basin. The authors describe the wide range of uses being made of legal doctrine and legal argument in ongoing disputes surrounding hydropower development in the Basin, putting to rest lingering caricatures of a single, 'ASEAN' way of navigating conflict. They call into question some of the common assumptions concerning the relationship between law and development. The book also sheds light on important questions concerning the global hybridization or crossover of public and private power and its ramifications for water governance. With current debates and looming conflicts over water governance globally, and over shared rivers in particular, these issues could not be more pressing.

The book comprises two parts: Pressure and Flow Well Testing (Part I) and Temperature Well Testing (Part II), and contains numerous authors' developments. Due to the similarity in Darcy's and Fourier's laws the same differential diffusivity equation describes the transient flow of incompressible fluid in porous medium and heat conduction in solids. Therefore it is reasonable to assume that the techniques and data processing procedures of pressure well tests can be applied to temperature well tests. The book presents new methods to determine the formation of permeability and skin factors from tests conducted in simulated wells, designing interference well tests, processing constant bottom-hole pressure tests, estimation of the formation temperature and geothermal gradients from temperature surveys and logs, in-situ determination of the formation thermal conductivity and contact thermal resistance of boreholes, temperature regime of boreholes (cementing of production liners), and the recovery of thermal equilibrium in deep and superdeep wells. Processing and analysis of pressure and geothermal data are shown on numerous field examples from different regions of the world. The book is intended for students, engineers, and researchers in the field of hydrocarbon geophysics and geology, groundwater searching and exploitation, and subsurface environment examination. It will be also useful for specialists studying pressure and temperature in parametric deep and superdeep wells.

Environmental protection and resource recovery are two crucial issues facing our society in the 21st century. Anaerobic biotechnology has become widely accepted by the wastewater industry as the better alternative to the more conventional but costly aerobic process and tens of thousands of full-scale facilities using this technology have been installed worldwide in the past two decades. Anaerobic Biotechnology is the sequel to the well-received Environmental Anaerobic Technology: Applications and New Developments (2010) and compiles developments over the past five years. This volume contains contributions from 48 renowned experts from across the world, including Gatze Lettinga, laureate of the 2007 Tyler Prize and the 2009 Lee Kuan Yew Water Prize, and Perry McCarty, whose pioneering work laid the foundations for today's anaerobic biotechnology. This book is ideal for engineers and scientists working in the field, as well as decision-makers on energy and environmental policies.

Multicriteria analysis is one of the most important fields of decision science. This book gives an outline of the formulation of an appropriate model and presents a comprehensive summary of the most popular methods for solving multicriteria decision problems. In addition to the classical approach the book introduces fuzzy and stochastic methodology, models with uncertainty, social choice and conflict resolution. All methods are illustrated with easy to follow simple examples. At the end of each chapter detailed case studies are given in water and environment management including inter-basin water transfer, urban water management, water allocation, groundwater quality management, forest treatment, ranking water resources projects, reservoir planning, water distribution network design and long-term watershed management. The new methodology and the wide variety of case studies are not easily accessible elsewhere.

Lagoons represent nearly 13% of the shoreline globally and around 5% in Europe. Coastal lagoons are shallow water bodies separated from the ocean by a barrier (e.g., narrow spit), connected at least intermittently to the ocean by one or more restricted inlets, and usually geographically oriented parallel to the shore-line. Coastal lagoons are flexible and usually able to cope with environmental change, yet nowadays they are under threat. This is partly due to climate change impacts (for example, sea-level rise and hydro-meteorological extreme events) but also due to more direct human activities and pressures. The book focuses on addressing these challenges through integrated management strategies seen in a land-sea and science-stakeholder-policy perspective. Pan-European management challenges are seen from the context of the perspectives of Policy, Environment and Modelling. Four case study lagoons in different geographical locations in Europe provide examples of some of the practical experiences and results around these challenges. Possible impacts on drainage basins and lagoons are introduced through integrated scenarios which were developed through a multi-science and land-lagoon science perspective combined with interactions and contributions from stakeholders and citizens. Issues around climate change impacts on environmental conditions in both drainage basins and lagoons are also included. The book derives from a collaborative EC-funded project entitled 'Integrated Water Resources and Coastal Zone Management in European Lagoons in the Context of Climate Change' comprising nine partner institutes with a wide diversity in the scientific disciplines covered.

This monograph is aimed at the practising hydraulic engineer. Work on it commenced at Professor Naudascher's instigation in 1982. Over the next six years all or some of the authors discussed progress at IAHR sponsored conferences at Esslingen, Melbourne, Lausanne and Beijing. With the authors scattered throughout the world, and all with other responsibilities, progress was bound to be slow. Completion was further delayed by the great increase in published technical literature in this area over the period 1982-1988. This literature continues to expand and with it our understanding of the air water flow phenomena. The monograph must therefore be seen as the authors' views on the state of the art around 1988. More recent references have been included for completeness.

This monograph has been a joint effort with most authors making suggestions and contributions to more than one chapter. Nevertheless, the chapter authors are primarily responsible for the material in their chapters.

Throughout the monograph symbols are defined when they are fist introduced and a list of symbols is included at the end of each chapter.

Many other people have contributed to this monograph, but the authors would particularly like to acknowledge the assistance given by Professor John McNown who has read, commented on and improved the style of the complete monograph.

This is the Paperback Student Edition of Water and Energy: Threats and Opportunities - Second Edition Rapid and important developments in the area of energy - water nexus over the last two to three years have been significant. This new edition of Water and Energy: Threats and Opportunities is timely and continues to highlight the inextricable link between water and energy, providing an up-to-date overview of the subject with helpful detailed summaries of the technical literature. Water and Energy has been up-dated throughout and major changes are: new chapters on global warming and fossil fuels, including shale gas and fracking; the consequences of the Deepwater Horizon accident in the Mexican Gulf and the Niger Delta oil spills; new developments in hydropower; and continued competition between food, water and energy. Water and Energy Threats and Opportunities, 2e creates an awareness of the important couplings between water and energy. It shows how energy is used in all the various water cycle operations and demonstrates how water is used and misused in all kinds of energy production and generation. Population increase, climate change and an increasing competition between food and fuel production create enormous pressures on both water and energy availability. Since there is no replacement for water, water security looks more crucial than energy security. This is true not only in developing countries but also in the most advanced countries. For example, the western parts of the USA suffer from water scarcity that provides a real security threat. Part One of the book describes the water-energy nexus, the conflicts and competitions and the couplings between water security, energy security, and food security. Part Two captures how climate change, population increase and the growing food demand will have major impact on water availability in many countries in the world. Part Three describes water for energy and how energy production and conversion depend on water availability. As a consequence, all planning has to take both water and energy into consideration. The environmental (including water) consequences of oil and coal exploration and refining are huge, in North America as well as in the rest of the world. Furthermore, oil leak accidents have hit America, Africa, Europe as well as Asia. The consequences of hydropower are discussed and the competition between hydropower generation, flood control and water storage is illustrated. The importance of water for cooling thermal power plants is described, as this was so tragically demonstrated at the Fukushima nuclear plants in 2011. Climate change will further emphasize the strong coupling between water availability and the operation of power plants. Part Four analyses energy for water - how water production and treatment depend on energy. The book shows that a lot can be done to improve equipment, develop processes and apply advanced monitoring and control to save energy for water operations. Significant amounts of energy can be saved by better pumping, the reduction of leakages, controlled aeration in biological wastewater treatment, more efficient biogas production, and by improved desalination processes. There are 3 PowerPoint presentations available for Water and Energy - threats and opportunities, 2e.

Molecular techniques are emerging as a rapid and powerful approach for microorganism detection. This project reviewed the efficacy of PCR assays for Cryptosporidium, Microcystis, adenovirus and ammonia oxidising bacteria, as well as candidate techniques for DNA extraction and inhibitor removal. The literature review led to an evaluation of DNA extraction kits and reagents for PCR; finalisation of assay formats; the development of PCR controls and Standard Operating Procedures (SOP); analysis of assay robustness using real samples; and completion of an Inter-laboratory trial using the SOP's developed. This book is co-published with Water Research Australia.

This project addressed a need for a sensitive, accurate and reliable testing method to aid assessment of the toxicity of algal blooms and assist water management. Increasingly, diagnostic dilemmas are resolved through the use of DNA-based technologies which often provide high sensitivity and specificity and are efficient both in terms of costs and time. However to date, no such test was available to the Victorian water industries. This project sought to bridge this gap by developing an automated DNA-based diagnostic assay for cyanobacterial bloom assessment blooms in Victorian waters. The assay exceeds expectation in its ability to accurately quantify levels of toxigenic cyanobacteria in bloom samples, retains exceptionally high specificity and sensitivity and each assay out-performs common conventional PCR approaches established in the literature. Four toxigen assays (microcystin, nodularin, cylindrospermopsin and saxitoxin) were designed, tested and optimised.

This title includes a number of Open Access chapters. Intended for a wide audience ranging from engineers and academics to decision-makers in both the public and private sectors, Biological Treatment of Solid Waste: Enhancing Sustainability reviews several technologies that help communities manage solid waste sustainably, while at the same time generating energy, revenue, and other resources. The book is divided into three topics: Microbial technologies for solid waste treatment Composting Biodrying Included within these larger topics are case studies and investigations into particular aspects of each, with attention paid to food waste, animal waste, municipal waste, and certain forms of industrial waste. The editor is an environmental engineer with an international reputation, and she has included her own research studies as well as that of her colleagues, many of which have been presented at international waste management conferences. She concludes that our world can no longer afford to consider waste as something that can be discarded with no regard for future use. Instead, if addressed correctly through policy and practice, solid waste can become a valuable resource.

In recent years the subject of pollution of natural waters by aquaculture has received considerable attention. With increasingly stringent regulation of wastewater quality from fish farms around the world, those involved in the industry need to be aware of the causes of pollution from fish and shellfish farms and of methods by which this pollution may be prevented. This book aims to bring the principles of wastewater treatment and other pollution control techniques for fish and shellfish farming to a wide audience of farmers, students, scientists and engineers; in fact anyone who works in aquaculture or pollution control. For this reason, the authors who have between them much experience in this area have written this important book with both the specialist and those new to the area in mind. As part of the growing Aquaculture Series, this title gives a comprehensive insight into this topic of vital importance to the aquaculture industry. This book should be on the shelves of all those involved in fish and shellfish farming and connected environmental issues, and available in universities and research establishments for students and professionals alike.

The absence of water supply infrastructure is a critical issue that affects the sustainability of cities in the developing world and the quality of life of millions of people living in these cities. Urban India has probably the largest concentration of people in the world lacking safe access to these infrastructures. This book is a unique study of the politics of water supply infrastructures in three metropolitan cities in contemporary India - Bangalore, Chennai and Kochi. It examines the process of change in water supply infrastructure initiated by notable Public Private Partnership's efforts in these three cities to reveal the complexity of state-society relations in India at multiple levels - at the state, city and neighbourhood levels. Using a comparative methodology, the book develops as understanding of the changes in the production of reform water policy in contemporary India and its reception at the sub-national (state) level. It goes on to examine the governance of regimes of water supply in Bangalore, Chennai and Kochi, and evaluates the role of the partnerships in reforming water supply. The book is a useful contribution to studies on Urban Development and South Asian Politics.
