Protector - simulating a contamination event

The Contamination module of the Protector app allows for determining the extent of a contaminant after its initial introduction to the system. This example simulates a contamination event with a tracer injected at a node, to determine where the tracer has traveled over a specified duration.

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, Contamination tab, enter a Source Node Location of 2222 for this example.

Junction 2222 is where the tracer will be injected.

11. Under Time, click Select Time.
12. In the Select Time dialog box, use the slider to set the Desired Time to 08:00 hrs.
13. Click OK.
14. Set the Event Duration to 4 hours.

15. Under Result Selection Set, click Browse (…) to open the Selection Set dialog box.
16. Click New.
17. In the New Selection Set popup, enter a name of “AFFECTED_FACILITIES” for this example.

18. Click OK to close the popup.
19. Click OK again to close the Selection Set dialog box.

Affected facilities identified by the Protector are saved to this AFFECTED_FACILITIES selection set.

The Contamination simulation is now ready to be run.

20. In the Protector, click Run.

Once the simulation is complete, in the model, the source location of junction 2222 is shown in yellow, and the affected facilities appear red.

21. In the Contamination tab, use the Color on Map settings to change these colors, if desired.
22. Click Purge Water to calculate the volume of water needed to purge the affected area.

23. Click OK to close the Purge Volume dialog box.

To set up notifications:

24. Click Options to open the Protector Options dialog box.
25. From the Notification Layer drop-down, select the propuse layer, which contains all customer details.

26. Click OK to save and close the dialog box.
27. Back on the Contamination tab, click Notify.

Affected customers are listed in the Notification tab.
