AWWA CSC91087

This paper is a continuation of work presented at the 1985 AWWA annual conference. A graphics-oriented computer program was developed as part of that effort to evaluate the concentration of water quality parameters throughout a water distribution network with multiple feed sources of different quality. Data input for the calculations consist of hydraulic results (flows and pressures) and concentrations of water quality parameters for all the water supply sources. The program is based on assumptions of steady state conditions, complete mixing at network nodes and no chemical reaction or degradation. Comparison of program results with actual field measurements verified the validity of the approach, reliability of the computational procedures and utility of the program in managing water quality for a water system with multiple supply sources. Figures include examples of graphic displays generated by the program. The color graphics program graphically displays any one of nine parameters (including concentration of a selected water quality parameter) in three selected color ranges on the color monitor. It can also produce graphs on hard copy, displaying lines of different patterns (representing the different colors) in order to distinguish between lines when graphs are reproduced in black and white.
