The Breakdown module of the Protector allows for determining which pipes in a hydraulic network need to be closed during the event of a pipe break. A Breakdown simulation accurately identifies pipes that can and should be closed in order to isolate a pipe element from the rest of the water system.

This example simulated a broken pipeline in the network to determine the affected facilities and closable valves, to isolate the broken pipe.

  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:

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

On the InfoWater Pro ribbon, Analysis panel, Run highlighted in red, and in the Run Manager, the Run button highlighted in red.

  1. Close the Run Manager.

To access the Protector:

  1. On the ribbon, in the Project panel, click Apps.
  2. From the Apps Manager, select Protector.
  3. Click Run.

On the InfoWater Pro ribbon, Project panel, Apps highlighted in red; and in the App Manager, the Protector app selected and highlighted in red, with Run selected.

  1. In the Protector app, switch to the Breakdown tab.
  2. Enter a Source Pipe Location of 2852.

Pipe 2852 was previously identified by the Protector Isolation module.

  1. Under Closable Devices, enable both Include Active Valves and Include Active Pumps.

The Protector app, on the Breakdown tab, with the Source Pipe Location and Closeable Devices settings configured for this example and highlighted in red.

Next, search for closable pipes on a selection or a domain:

  1. Under Closable Pipes, make sure that Domain is selected.
  2. Click Edit Domain to open the Domain Manager, to select the closable pipes.
  3. In the Domain Manager, under Element Source, select Selection Set.
  4. Use the drop-down to select the CLOSABLE_PIPES selection set.

The Domain Manager, with Selection Set enabled as the Element Source, and CLOSABLE_PIPES selected from the drop-down, both highlighted in red.

The CLOSABLE_PIPES selection set contains all pipes with closable valves.

  1. Click Add.
  2. Click Close to exit the Domain Manager.
  3. Under Result Selection Set, use the Affected Facilities drop-down to select AFFECTED_FACILITIES.

Affected facilities are all isolated pipelines due to the broken pipe.

  1. Enable Include Isolated Area by Connectivity Search.
  2. In the Closed Facilities drop-down, select CLOSED_FACILITIES.

This selection set was previously created by a Protector Isolation run.

The Breakdown simulation is now ready to be run:

  1. In the Protector, click Run.

The Protector, Breakdown tab, with all settings for this example configured, and the Run button highlighted in red.

  1. Once the simulation is complete, in the model, the source location of pipe 2852 is shown in yellow, the affected facilities appear red, and the closed facilities are gray.
  2. In the Isolation tab, use the Color on Map settings to change these colors, if desired.
  3. Click Purge Water to calculate the volume of water needed to purge the affected areas.
  4. Click OK to close the Purge Volume dialog.
  5. Click Close to exit the Protector.
