Compare isolation trace solutions

Included with ArcGIS Solutions for Water are two solutions that trace a water network. These solutions are designed for specific workflows and environments. The Utility Isolation Trace solution is designed for use on a web browser. The Water Utility Network Editing and Analysis solution is a desktop based solution. Use the section below to learn more about the use cases and limitations of these solutions. By understanding the workflows and limitations of these solutions, you can best determine which will meet the needs of your organization.

Utility Isolation Trace

Utility Isolation Trace is a web based solution which uses Web AppBuilder for ArcGIS (Developer Edition) and the Network Trace widget to run the trace. This solution uses a geoprocessing model to run a find connected trace to identify the valves required for a shut down.

This web based solution is not best for identifying customers as it does not handle valves at dead end segments. This results in the geoprocessing model returning the closest valves, regardless of if the valve is required to close.

Web Trace Valves Returned

In the image above, you can see by closing valves A and B, valves C, D, and E are not pressurized and therefore do not need to be closed. If the application's user can identify this, the valves can be bypassed, or skipped, geoprocessing re-run, and an accurate customer list can then be created.

Web Trace Valves Skipped

Water Geometric Network Editing and Analysis

Water Utility Network Editing and Analysis is a desktop based solution which uses ArcMap and a series of add-ins and toolbars to run the trace and publish the results to a hosted feature layer.

Unlike the web based solution, this solution does take into account dead end valves when running an isolation trace. Once the trace is run locally, the results can be appended to a hosted feature layer, allowing field crews access to the shutdown information.

Desktop Trace Results

In the image above, you can see the trace results include valves A and B only. The additional valves are automatically skipped.
