Abstract: Graphs are developed based on the concept of feasible diameter set for the rapid design of sanitary sewers. They are developed for various hydraulic criteria, such as full flow and best hydraulic cross section, taking into account the hydraulic constraints such as velocity and partial depth of flow. These graphs can be used by practicing engineers to perform quick and improved design, thereby eliminating any need for trial-and-error procedures. Procedures for preparation of the graphs are detailed. An illustrative example describing the application of design graphs is included.
