Protector - trace poor quality

The Event Trace module of the Protector can be used to conduct a trace algorithm to determine the extent of contamination from a selected source node or nodes at a specific time. Once the Event Trace simulation is run, all pipes and nodes that contributed flows to the selected node are displayed.

This example traces poor quality found in a network after a customer complaint.

1. Double-click the desired project .aprx file to open ArcGIS Pro.
2. Click the InfoWater Pro tab to open the InfoWater Pro ribbon.
3. In the Project panel, click Initialize.

Start by running a simulation for the current scenario:

4. On the InfoWater Pro ribbon, in the Analysis panel, click Run to open the Run Manager.
5. Click Run to run the simulation and create an output for the current scenario.

6. Close the Run Manager.

To access the Protector:

7. On the ribbon, in the Project panel, click Apps.
8. From the Apps Manager, select Protector.
9. Click Run.

10. In the Protector app, switch to the Event Trace tab.

First, identify the source of the event:

11. Under Step 1, make sure that Domain is selected.
12. Click Edit Domain.

13. In the Domain Manager, click Clear to clear any previous selections.
14. Under Element Source, enable Selection Set.
15. Use the drop-down to select the POOR_QUALITY_NODE selection set.
16. Click Add.

17. Click Close to exit the Domain Manager.
18. Back on the Event Trace tab, click Select Time.
19. In the Select Time dialog box, use the slider to set the Desired Time to 06:00 hrs—the time of the complaint in this example.
20. Click OK.
21. On the Event Trace tab, click Trace.

Under Step 2, determine the area affected by the poor water quality source. Notice that after running the trace, source 2306 now appears in the Source(s) Identification box.

22. Select the 2306 source, so that it is highlighted in blue.
23. Under Affected Customers, use the Selection Set drop-down to select AFFECTED_FACILITIES.
