Golden State Water Company owns and operates 38 water systems in California. The California Public Utilities Commission requires GSWC to file Rate Case plans every three years. In an effort to streamline the detailed reporting requirements, GSWC executed a pilot project to determine the feasibility and potential value of implementing GIS-based hydraulic models to develop justifiable, prioritized capital investment plans. GSWC commissioned Innovyze and Wachs Water Services to convert AutoCAD system maps to geodatabases, analyze existing maintenance datasets, perform field asset inventories, conflate hydraulically significant data discrepancies and build GIS-based hydraulic and asset management models. This presentation will explore the challenges and creative approaches that leveraged existing non-spatial AutoCAD datasets, existing geospatial hydraulic models and legacy maintenance data to economically generate prioritized capital plans.
