Drought Management of Existing Water Supply System

Abstract

A multi‐objective linear program is developed to study the operation of a metropolitan water supply system during drought. The Indianapolis Water Company is used as a case study. Twelve pressure districts, three reservoirs, and eight supply sources are included in the model. Four noncommensurate and conflicting objectives are identified and built into the linear program. The model is used to analyze operations during the drought of record and to develop trade‐off curves among the objectives. Experience with the model suggests that this methodology can provide information that can aid operational decision making.
