GIS Utility Network Mapping & Hydraulic Model Update

LDG delivered GIS and engineering services to the Mohawk Valley Water Authority [MVWA] in Utica, NY, to achieve two key objectives: updating the GIS data model and recalibrating the existing all-pipe hydraulic model. MVWA operates a comprehensive water system serving over 125,000 people across 150 square miles, producing an average of 19 million gallons per day [MGD] through approximately 750 miles of piping, 25 storage tanks, and 21 pumping stations.

GIS Update

The first objective involved updating the GIS data model by utilizing industry-standard tools to clean topology, standardize datasets, and develop an enterprise geodatabase compatible with the hydraulic model. MVWA transitioned to Esri’s Utility Network database structure and upgraded to ArcGIS Enterprise, enhancing resource scalability and enabling advanced analyses for improved decision-making. This update encompassed the creation and documentation of information products and workflows, revision of the GIS data model, data migration, and implementation of the updated system.

Hydraulic Model Update

The second objective focused on transforming the existing all-pipe hydraulic model into a “sustainable” version, incorporating all pipes, valves, and hydrants, and aligning with GIS data for comprehensive flow analysis. Key updates included recalibrating the InfoWater model, which had not been updated since 2007, integrating data from MVWA’s Neptune AMI system, and incorporating NYS SAM points. The process involved adding hydrants and valves, redefining pressure zones, verifying data, and integrating SCADA system data. LDG developed a methodology for automating updates to the hydraulic model, ensuring it remains current with GIS changes.
