Title: Combined sewer overflow: A management study. Technical report

Technical Report ·
OSTI ID:5858239

This project is part of the National Network for Environmental Management Studies under the auspices of the Office of Cooperative Environmental Management of the U.S. Environmental Protection Agency. In many older cities in the U.S., the capacity of the combined sewer is exceeded on a daily basis due to both-wet weather storm surges and increased volumes of waste generated by new development. As a result, billions of gallons of untreated sewage are discharged on an annual basis into the nation's marine bays and estuaries in episodes called 'combined sewer overflow.' There are two primary reasons for the increasing frequency and severity of overflow episodes: the population of cities in coastal areas are growing at rates that far exceed the ability of the sewer infrastructure to accommodate them; the built-in inefficiencies of the original design of the combined sewer are being exploited by many municipalities to compensate for the increased volumes of sewage associated with the growth in population. Because each combined sewer, the area that it drains, and the receiving water into which it discharges constitutes a unique system, a management strategy should be site-specific. The document proposes a framework within which a site-specific and cost-effective management strategy may be formulated. By necessity, the emphasis is on providing tools and methods rather than explicit solutions.
