Tucson Water Department is a municipal water company serving potable and reclaimed water to over 700,000 people in the Tucson, Arizona area. This paper discusses the process and problems encountered creating all-pipe pressurized water distribution hydraulic models using its enterprise GIS geodatabase. Using these models gives more accurate hydraulic analysis results related to master plan review, fire flow, pressure, supply, water quality, water age, planned outages, and pumping optimization.
