Using Criticality to See What Happens When a Pipe is Taken Out of Service

Part of the Hydraulics and Hydrology Video Series (more info)

When a pipe break occurs or a pipe needs to be taken out of service, customers may be impacted when the isolating valves are closed. Did you know that the Criticality and Segmentation tools in WaterCAD and WaterGEMS can tell you details of what happens in this case, such as the demand shortfall? To learn more, watch this short video and check out the other resources at the bottom. The video covers the following:

  • Establishing and color coding segments with Segmentation.
  • Reporting demand shortfall per segment with Criticality.
  • Using the External Customer Meter tool to identify affected customers.

Criticality is available in both WaterCAD and WaterGEMS V8i. For resources on learning how to use Criticality, check the "See Also" at the bottom of this post.
