A municipal water utility’s distribution data, built up over years in an ArcMap geometric network, assessed, cleaned and staged for the ArcGIS Utility Network before the geometric network reaches end of life.
Esri’s geometric network retires with ArcMap. ArcGIS Pro does not support it, so the utility’s water distribution data, and every workflow built on it, had to move to the Utility Network. At the same time, inspection and maintenance workflows were moving to a new asset management system.
The data itself carried years of edits: features without global IDs, pipes broken at vertical bends, valves and hydrants with missing attributes, and connectivity problems that only showed up when a trace failed.
Data only moves forward when it passes the gate behind it. Each stage follows Esri’s Utility Network migration pattern, with the utility’s own field mapping workbook and a scripted legacy geodatabase builder doing the repetitive work.
Confirm source data has global IDs, download the Utility Network foundation, adjust the asset package spatial reference, extend the data model where the utility needs it.
Build the data loading workspace, populate it from the legacy geodatabase with a scripted builder, run the QA gate, execute the load.
Stage the Utility Network in the enterprise geodatabase, apply the asset package, enable topology and review errors.
Resolve dirty areas and connectivity errors, define subnetwork controllers from towers through transmission to distribution, update and validate subnetworks.
Publish by subtype, rebuild editing workflows in ArcGIS Pro, test isolation traces and integrate with billing and asset management.

The cleanup phase ended with the network error list empty and subnetworks defined from source to service.
Field mapping, attribute decisions and domain changes are recorded where the next person can find them.
Editing, tracing and publishing are rebuilt for the Utility Network, not patched around the old one.
