The original version of EXEC/OP, a Fortran computer program that synthesizes municipal wastewater treatment system designs from a specified list of unit treatment processes, has been updated. Revisions have been made in several of the unit process performance sub-models to produce results that conform more closely to accepted design practices. This new reference manual describes the elements of the EXEC/OP program, gives instructions on how to prepare input data for the program, and illustrates its application to a sample design problem. Also included is a listing of the updated Fortran source code and definitions of the program's variables. A computer tape of the Fortran source code is available through NTIS.
