The nation's sanitary sewer infrastructure is aging, with some sewers more than100 years old. 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. Addressing aging water infrastructure challenges is one of the top national water program priorities, and a top priority of the U.S. Conference of Mayors. Rainfall-derived infiltration and inflow (RDII) into sanitary sewer systems has long been recognized as a major source of operating problems that cause poor performance of many sewer systems including SSOs. The extent of infiltration also correlates with the condition of aging sewers. To assist communities in developing SSO mitigation plans, the U.S. Environmental Protection Agency (EPA) entered into a cooperative research and development agreement (CRADA) with CDM Smith in 2002 to develop an easy to use public domain computer toolbox and associated technical guides. The toolbox is called SSO Analysis and Planning (SSOAP).
Purpose is to provide an update on SSOAP.
