The major objective was to apply a previously developed control algorithm for reducing costs of operation for the Roxborough High Service-West Oak Lane district of Philadelphia containing two pumping stations and one elevated storage tank. Generation of the control algorithm's pump switching lines was accomplished with a system of programs for simulating demand (using Fourier series) and operation of the district (using a regression analysis model) based on past logging data. The complete software system for generating the control algorithm and performing simulation studies for a water distribution with elevated storage is programmed in FORTRAN IV for the GE-RESD timesharing computer (GE-635).
