Approximately 15,000 combined sewer overflow events (CSOs) occur annually, and during peak storm events, they release about 1.2 trillion gallons of waste, 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. Commissioned by the EPA, written by internationally recognized experts, and subjected to extensive peer review, Management of Combined Sewer Overflows provides the latest information in water science from analysis of contaminants to long-term CSO control plans.
