Using an ArcGIS Utility Network to build a model

Product(s): WaterGEMS, SewerGEMS
Version(s): CONNECT Edition (ArcGIS Pro integration only)
Area: Layout and Data Input


Background: ESRI introduced an advanced network management component called the Utility Network.  When defining an ArcGIS geodatabase, users can optionally decide to include a Utility Network.

Can I construct or update my hydraulic model using an ArcGIS geodatabase that includes a Utility Network?


Yes.  ModelBuilder works directly with the underlying features and therefore can work with a geodatabase whether it includes a Utility Network or not.


  • On the “Specify Spatial and Connectivity Options” step (of the ModelBuilder wizard) be sure to toggle on the “Establish connectivity using spatial data” option.  Feel free to use a very small “Tolerance” value (the Utility Network maintains precise accuracy when placing connected features within ArcGIS).
  • As of January 2022, the available versions of the OpenFlows products do not yet directly use the alias "description" fields. The "code" value will be shown and available to be mapped. (see related discussion here). We are investigating the possibility of adding the ability to use the "Description" directly, in a future version. Tracking reference # 782625.
