Lose yourself in the vast sewer networks that lie beneath the world's great cities - past and present. Let detailed archival plans, maps and photographs guide you through these subterranean labyrinths - previously accessible only to their builders, engineers and, perhaps, the odd rogue explorer. This execrable exploration traces the evolution of waste management from the ingenious infra-structures of the ancient world to the seeping cesspits and festering open sewers of the medieval period. It investigates and celebrates the work of the civil engineers whose pioneering integrated sewer systems brought to a close the devastating cholera epidemics of the mid-19th century and continue to serve a vastly increased population today. And let's not forget those giant fatbergs clogging our underground arteries, or the storm-surge super-structures of tomorrow.
This book documents state of the art research designed to compliment the advances being made in the global water quality sector. Book 2 provides further detail on supporting programmes.
This book outlines the current trends and challenges in monitoring rural water and sanitation services, in particular at country level. "From Infrastructure to Services" reveals important breakthroughs in country-led and country-wide monitoring of rural and small towns water supplies. It presents a state-of-the-art of strengthening monitoring water supply and sanitation in developing countries.Now that the coverage of water and sanitation in developing countries is increasing rapidly, there is a pressing need to ensure the new services continue to work. Information and Communication Technologies (ICTs) play a part; concern about value for money in development finance and the need to protect huge investments in water and sanitation all add urgency to the task. This book is essential reading for program managers and policy makers in the water, sanitation, and hygiene sector, both in development agencies and government departments. It should also be read by researchers and students in the WASH sector."

One of the most exciting new trends in water quality management today is the movement by many cities, counties, states, and private-sector developers toward the increased use of Low Impact Development (LID) to help protect and restore water quality. LID comprises a set of approaches and practices that are designed to reduce runoff of water and pollutants from the site at which they are generated. By means of infiltration, evapotranspiration, and reuse of rainwater, LID techniques manage water and water pollutants at the source and thereby prevent or reduce the impact of development on rivers, streams, lakes, coastal waters, and ground water. This book summarizes 17 case studies of developments that include Low Impact Development (LID) practices and concludes that applying LID techniques can reduce project costs and improve environmental performance. This book also compares green energy programs and policies in China and the United States.
This monograph provides comprehensive coverage of technologies which integrate adsorption and biological processes in water and wastewater treatment. The authors provide both an introduction to the topic as well as a detailed discussion of theoretical and practical considerations. After a review of the basics involved in the chemistry, biology and technology of integrated adsorption and biological removal, they discuss the setup of pilot- and full-scale treatment facilities, covering powdered as well as granular activated carbon. They elucidate the factors that influence the successful operation of integrated systems. Their discussion on integrated systems expands from the effects of environmental conditions to the removal of various pollutants, to regeneration of activated carbon, and to the analysis of such systems in mathematical terms. The authors conclude with a look at future needs for research and development. A truly valuable resource for environmental engineers, environmental and water chemists, as well as professionals working in water and wastewater treatment.

Little is known about the volume of international recycling in Asia, the problems caused and the struggle to properly manage the trade. This pathbreaking book addresses this gap in the literature, and provides a comprehensive overview of the international trade flow of recyclable waste in Asia and related issues. The expert contributors discuss the various types of recyclable waste that Asian countries import, and illustrate that there are consequently higher numbers of cheaper informal recyclers with lower pollution control costs than formal recyclers with more expensive but environmentally sound technologies. They explore how governments across China, Vietnam, South Korea and Japan are therefore struggling to minimize the negative impact from informal recycling via trade regulation of recyclable and hazardous waste and comprehensive cooperation mechanisms to promote efficient use of resources. Preventive measures against illegal and/or improper transboundary movement of hazardous waste in Asia are also analysed. This unique and fascinating book aims to facilitate a common understanding of the issues caused by international recycling in Asia to encourage effective international and regional cooperation in order to establish a sound recycling system. As such, it will prove an invaluable resource to academics, researchers and students with an interest in Asian studies, economics, environmental studies, international economics and industrial economics.

Agriculture in the Murray-Darling Basin of Australia represents a controversial 'policy experiment' comprising large capital investments, innovation and enterprise across a hundred-year period. This book, which contains contributions from some of Australia's foremost economic, social science and public policy researchers and writers, examines the evolution of public policy frameworks that transformed water management from initial exploitation for irrigation as a dominant single use to a dynamic multiple use resource system. Water Policy Reform provides both analytical insights and examples of successes and failures in developing water policy in a complex and politically-contested environment. As such, this work attempts to develop a comprehensive management plan for the Basin and provides novel and invaluable lessons for an increasingly global problem. This well-researched study will interest both economists and those with public policy interest in academia and the public sector, including development agencies concerned with sustainable water resource management.
