Description:
Rainfall Derived Infiltration and Inflow (RDII) into sanitary sewer systems has long been recognized as a source of operating problems in sewerage systems. RDII is the main cause of sanitary sewer overflows (SSOs) to basements, streets, or nearby streams and can also cause serious operating problems at wastewater treatment facilities. Thus, there is a need to develop proven methodologies and computer tools to assist SSO communities in developing an optimal capital improvement program that is in line with the projected annual capital budget and provides flexibility in future improvements. To assist municipalities in developing plans to mitigate SSO problems, the USEPA signed a cooperative research and development agreement (CRADA) with Camp, Dresser, and McKee, Inc. (CDM) to develop a public-domain Sanitary Sewer Overflow Analysis and Planning (SSOAP) Toolbox. The CRADA will also prepare a technical guide for analyzing infiltration/inflow, performing capacity analyses of sanitary sewer systems, and developing SSO control plans using the toolbox. The Toolbox will be ready soon for beta testing by the public. The SSOAP and the RDII methodology in performing capacity analyses of sanitary sewer systems and developing SSO control plans will be described in this presentation.
