Optimization of a Municipal Ground Water Production System in North-Central Oklahomaby Blaine T. Reely, City of Enid, Enid, United States,
Abstract: A management model is being developed to optimize the municipal groundwater production system which supplies drinking water for the City of Enid, Oklahoma. The system is comprised of one hundred fifty-five wells located within five well fields, which produce from two separate aquifiers. The major factors which affect the cost of production for an individual well include: 1) electric power usage; 2) water rights/royalty provisions; and 3) water well operation and maintenance requirements. The type of management model which was formulated is classified by Gorelick (1983) as a linked simulation-optimization model. The basic model is based on a linear program management model which contains an economic objective function with operational and hydraulic constraints. The management model is linked with a groundwater simulation model, and an iterative procedure is followed to obtain the optimal production schedule. This model allows the water system manager to rapidly adjust to varying demands for water and changes in operational status, with a high level of confidence that the system operation is efficient and cost- effective.
