Decision Support System for Long Term Planning of Rural and Urban Water Supply Systems Cost in Oklahoma

The purpose of this paper is to develop an economic Decision Support System (DSS) to be used as a management and planning tool by regional and local water planners for the sequential expansion, upgrading, and regionalization of drinking water treatment plants at a minimum total discounted future cost. The DSS will aid water resource managers to make cost minimizing investments and provide investment options on existing and future water treatment plants and to evaluate efficient supply, transmission, treatment, staging, and distribution of high quality drinking water to Oklahoma residents.
