A review was made of several computer programs capable of simulating sewer flows under surcharge or pressurized flow conditions. A modified version of the EXTRAN module of the SYMM model, called PFSM, was developed and attached to the FHYA Pooled Fund PFP-HYDRA package. The microcomputer-based PFSM can be used to compute flow rate, velocity, and gradeline elevations under surcharge conditions. It will also determine the location and duration of the surcharge.
