Impact/Purpose:
To assist communities with sanitary sewer evaluations and in developing SSO mitigation plans
Description:
In the United States, sanitary sewer infrastructure is aging, with some sewers dating back over 100 years. Nationwide, there are more than 19,500 municipal sanitary-sewer collection systems serving an estimated 150 million people and about 40,000 sanitary sewer overflow (SSO) events per year. Rainfall-derived infiltration and inflow (RDII) into sanitary sewer systems has long been recognized in many sewer systems as a major cause of poor performance and operating problems, including SSOs. To assist communities with sanitary sewer evaluations and in developing SSO mitigation plans, the U.S. Environmental Protection Agency (EPA) in 2002 entered into a cooperative research and development agreement (CRADA) with CDM Smith (Cambridge, Massachusetts.) to develop a public domain computer toolbox and associated technical reports. The set of tools is referred to as SSO Analysis and Planning (SSOAP).
