Optimal Design of Water-Distribution Networks with GIS

Abstract

Many powerful optimal design models have been developed for municipal water-distribution networks, but few are in practical use since they are difficult for water engineers to understand and require an extensive data base for implementation. To aid in technology transfer of water-distribution system optimizers, a prototype decision support system WADSOP (Water Distribution System Optimization Program) is presented to guide water-distribution system design and analysis in response to changing water demands, timing, and use patterns; and accommodation of new developments. WADSOP integrates a geographic information system (GIS) for spatial database management and analysis with optimization theory to provide a computer-aided decision support tool for water engineers. Several comparative studies show improved performance over published results. A real-world case study for the city of Greeley, Colo., water-distribution network is also presented.
