OPERATION OF A METROPOLITAN WATER SUPPLY SYSTEM DURING DROUGHT (LINEAR PROGRAMMING, MULTIOBJECTIVES, SIMULATION)
Abstract
A multiobjective linear program has been devised, built, and tested to study the operation of Indianapolis Water Company, the primary supplier of water for the Indianapolis metropolitan area, during a drought. The basic mathematical model represents the three major supply sources (White River, Fall Creek, and Eagle Creek Reservoir) and four minor supply sources, with a fourth major source (South Well Field) added to the model to represent future conditions; the twelve pressure districts; variability in consumer demand; reservoir evaporation; and pumping costs. Four conflicting objectives have been identified for the system, and built into the math program. The objectives are: maximize revenue, maximize reliability, maximize end-of-optimization-sequence reservoir storage, and maximize streamflow. The 1940-41 drought is used as the basis for the study. Historical streamflows are used with current and future demand levels. The math program is used to study both long-term and real-time operation during the drought. The model studies prove that the results obtained can be used to aid in operational decision making by the Water Company.
