The Utility Isolation Trace app allows the operator to specify a location, such as a main break, and determine which valves to close and what hydrants and customers will be out of service.
This solution uses a custom widget in Web AppBuilder for ArcGIS to run the isolation trace. To determine the isolation area, information is passed to a geoprocessing service to run the analysis and process the results. The results are returned to the app, where a valve can be skipped and the process re-ran. When the isolation area has been verified, the results can be saved to the Outage Details feature service that is included with the Outage Viewer solution.
Note: This app only finds the closest valves and does not evaluate whether there are dead ended segments. If you are looking for advance isolation logic, use the isolation trace tools that are part of the Water Utility Network Editing and Analysis solution.
Utility Isolation Trace requires specific technical experience and software.
