Sanitary sewer design using EPA storm water management model (SWMM)

Traditional sanitary sewer design uses detailed design tables that contain all the necessary information to complete the design. An alternative approach is to use modeling software, such as the EPA SWMM model. This paper details the application of the EPA SWMM model to design the sanitary sewer system of a proposed 62 lot development. Typically SWMM is thought of almost exclusively as a storm water system analysis tool, but this application shows how it can also be used for sanitary sewer analysis and design. The paper details how the SWMM model parameters were set to handle infiltration and inflow as well as base residential sanitary flows. © 2009 Wiley Periodicals, Inc.
