Listed below are common questions about the Utility Isolation Trace.

• If I need help configuring the Utility Isolation Trace, what should I do?
• I have not configured the Water Leak Investigator solution, can I still use the Utility Isolation Trace at my organization?
• Can the Utility Isolation Trace be configured for other types of networks?
• When running the Isolation Trace geoprocessing model, I get an error No flag found from the flag junction. Is there a step that I am missing?
• When published to ArcGIS Server, an error is logged that a value is not part of the water distribution dataset and value is not part of the geometric network.
• The geoprocessing model does not take into account inoperable valves and unlooped mains. Are there any tools that can take these features into consideration?

If I need help configuring the Utility Isolation Trace, what should I do?

If you need support configuring the Utility Isolation Trace at your organization, please contact Esri Technical Support. If you'd like to get help from other water utility community members, post your question on the Utilities and Telecommunications space on GeoNet.

I have not configured the Water Leak Investigator solution, can I still use the Utility Isolation Trace?

Yes. The Leak Investigator and Utility Isolation Trace solutions complement each other in the leak and shutdown process. Water Leak Investigator is not required to use the Utility Isolation Trace. If you have not deployed the Water Leak Investigator solution, when configuring the map for the Utility Isolation Trace application, simply omit adding the Leak Investigator service to the map. If you organization later deploys the Water Leak Investigator, the leak report layer can be added to the Isolation Trace map at a later time.

Can the Utility Isolation Trace be configured for other types of networks?

Yes. To configure the model for another type of network system, you can use Generate Isolation Trace Toolbox tool. With this tool, you can simply specify your geometric network and update the parameters based on the features that will stop and be the results of an isolation trace. The resulting IsolationTrace.pyt will be configured for the network that you have used to generate the toolbox.

When running the Isolation Trace geoprocessing model, I get an error No flag found from the flag junction. Is there a step that I am missing?

Yes. Before running the model, be sure to add at least one flag. Once you have placed a flag, execute the model.

When published to ArcGIS for Server, an error is logged that a value is not part of the water distribution dataset and value is not part of the geometric network.

This error can occur when the geoprocessing model is copied to ArcGIS for Server and the paths and to the data sources break. There are a number of ways to troubleshoot and resolve this issue. First, update the model on ArcGIS for Server to use the correct paths and restart the service. Additionally, the paths to the data need to be accessible by all ArcGIS for Server machines. Use UNC or a shared path to ensure the data is on each machine in the correct location.

The geoprocessing model does not take into account inoperable valves and unlooped mains. Are there any tools that can take these features into consideration?

The Find Connected geoprocessing tool is limited in its capabilities and will not take into account inoperable valves and unlooped mains. The Water Geometric Editing and Analysis solution provides this tracing capabilities using ArcGIS for Desktop and a series of tools to return the results and publish the results to a feature service.
