This paper has described the issues and methodologies associated with utilization of Geographic Information Systems (GIS) technologies in construction of a hydraulic model including: history of GIS system; resolution of GIS format and types of data errors required for hydraulic modeling; conversion of the GIS into a format compatible with hydraulic modeling using the Reduce, Skeletonize, and Trim (RST) translator; and, impacts to the modeling cost and hydraulic volume which are realized from implementation of GIS systems. The evolution of GIS systems has led to the availability of large data sets which can be utilized during a water master plan. In order to efficiently and effectively use this data, the capability of processing GIS information to create hydraulic models is required. Additionally, large models can also now be justified by the ability to perform accurate demand allocation utilizing extremely detailed population and water use information. The results of these efforts, as detailed herein, are models which contain significantly greater amounts of the distribution system volume, have significantly lower cost per pipe, and show no adverse impact for overall cost to the customer. Realization of these benefits will require that consultants utilize GIS in their modeling efforts to be competitive in the marketplace.
