Abstract

GIS and Hydraulic Model - Synergistic Workflows for Data Maintenance
Track: Water, Wastewater, and Stormwater
Authors: Leanne Talbott, Haritha Vendra

Mesa Consolidated Water District (Mesa) serves a population of about 110,000 in a service area spanning about 18 sq. mi in Orange County, CA. Mesa has been dedicated to serving the community's water needs over the last 50 years. The GIS at Mesa can be classified as being Mature, with an enterprise GIS being served over the intranet, and field mobile users. It was a natural progression to build a hydraulic model of the District-wide system leveraging GIS. In addition to the infrastructure, several other model components such as demands were input using GIS. Mesa also continues to make updates to the GIS which will be synchronized to the model. The goal of this paper is to discuss the synergistic workflows for building, and maintaining a hydraulic model using GIS data. It will also detail the preparation of GIS data for model, challenges faced, and benefits of the integrated environment.
