Step-by-step guide

In IWLive Pro, once a pipe burst is identified and its impact visualized, you can create a response run to find a pipe isolation solution that minimizes the impact on the network and customers.

In this example, a suspected pipe burst was identified in DMA 1337 on April 2 after 5 PM. A series of burst incidents were created, and the location was narrowed to one of the offtakes, which is represented in Incident 4.

The IWLive Pro interface, with the location of a suspected pipe burst called out by a red arrow in the GeoPlan.

To configure a response run, first, create a child run of the incident.

  1. On the Headlines page, Schedule tab, right-click the baseline and select Go to baseline.

The Headlines page, Schedule tab, with the context menu for the baseline expanded and Go to baseline being selected and called out with a red arrow.

  1. In the Run Manager, expand Initial Model Run.
  2. Right-click Incident 4 and select Create child run.

In the Run Manager, under Initial Model Run, the context menu for Incident 4 expanded, with Create child run being selected and called out with a red arrow.

  1. In the New Run dialog, leave all options set to the defaults and click OK.

The New Run dialog, with all options set to the defaults.

Next, create a pipe isolation.

  1. In the GeoPlan, zoom to the pipe where the burst is configured.
  2. If the Trace toolbar is not enabled, right-click the toolbar and select Trace.

The context menu for the toolbar expanded, with Trace selected and called out with a red arrow.

  1. On the Trace toolbar, click Isolation Trace.
  2. In the GeoPlan, select the pipe.

On the toolbar, Isolation selected and highlighted in red. In the GeoPlan, the pipe where the burst is configured selected and called out with a red arrow.

To highlight the pipes that need to be isolated:

  1. In the Isolation window, select Show valves to be closed.
  2. In the Close valves from drop-down, set a time during the simulation for the valves to close, such as 5:30 PM on April 2.
  3. Set Close valves until to the following day, so the valves remain closed until the simulation is complete.
  4. Click Close valves.

In the Isolation window, the settings configured for this example and highlighted in red, and Close values being selected.

  1. Click OK to close the notification that two valves have been closed.

Notification of successful valve closure.

To confirm that the valves have been shut:

  1. In the GeoPlan, select one of the valves and open the Properties window.
  2. In the Initial values table, next to Pipe Status, click More (…).

In the Properties window, the Initial values table, with More (…) for the Pipe Status called out with a red arrow.

  1. In the Editor, in the Pipe Closed column, verify the pipe status.

In the Editor table, the Pipe Closed status, which indicates that the pipe is closed, highlighted in red.

  1. Click OK.
  2. Repeat this process for the other valve.

Now, run the simulation.

  1. From the Run Manager window, right-click the response run and select Simulate.

The Run Manager, with the context menu for the response run expanded and Simulate being selected and called out with a red arrow.

  1. In the Simulation License pop-up, click OK.

Once the simulation is complete, apply the Pressure Contour theme.

  1. Select Window > Themes.

The Window menu expanded, with Themes being selected and called out with a red arrow.

  1. In the Theme drop-down, select Pressure Contour.

In the Themes window, Pressure Contour selected and highlighted in red, and in the GeoPlan, the pressure contour theme applied.

  1. On the Replay toolbar, click Play.
  2. Click Pause when the timeline is between 5 PM and 5:30 PM.
  3. Zoom out for a better view and notice that between 5 and 5:30 PM, the impact of the burst affects the entire area identified previously.

The GeoPlan, with the Replay timer paused at 5:15 PM and highlighted in red, and the Map view showing the affected area before the pipe isolations.

  1. Play the simulation again until the isolations are active.
  2. Click Pause.

The affected area in the network is reduced to only the small area shown, thereby minimizing the impact on both the network and the customers.

The Replay timer paused at 6 PM and highlighted in red, and in the Map view, the much smaller affected area after the pipe isolations is highlighted in purple.
