Management of Combined Sewer Overflows
There are approximately 10,000 combined sewer overflow (CSO) locations in the United States. During peak storm events they can release about 1.2 trillion gallons of waste and up to 95% of a municipality's raw sewage into surface waters. Although many cities have initiated programs, the CSO problem remains largely unsolved and continues to be a major area of responsibility for environmental professionals, engineers, and public works officials.
Sponsored by the EPA, written by internationally recognized experts, and subjected to extensive peer review, Management of Combined Sewer Overflows provides the latest information on the subject from analysis of contaminants to long-term CSO control plans. Coverage includes:
Abatement or prevention of pollution stormwater runoff and CSOs is one of the most challenging areas in the environmental engineering field. The facts of life - from an engineering standpoint - are difficult to face in terms of design and cost. And operational problems can be just as foreboding. A reference for anyone combating urban wet-weather-induced water pollution, Management of Combined Sewer Overflows covers the gamut of engineering requirements, from pollution problem assessment and associated tools, to management and control planning and design.

"[T]his book benefits from the extensive experience of authors from the U.S. Environmental Protection Agency. The book includes a comprehensive overview of combined sewer overflow (CSO) history and impacts, as well as strategies for mitigation. … The authors provide extensive references … . The wealth of experience of the authors makes [this book] a valuable reference for practicing professionals charged with controlling CSOs. However, this book is also recommended reading for anyone interested in better understanding the impacts of CSOs on the environment and our options for reducing their impacts in the future."
