Junction nodes are points placed at the intersection of two or more pipes (intersections or tees). Junctions are used to represent points of water consumption or inflow, points where specific analysis values (e.g., pressure, concentration) are desired, and at points where pipe attributes (e.g., diameter, material) change.  Junction nodes must have their elevation above datum (e.g., sea level) specified in order for pressure computations to be meaningful.


How do I...

Create a Junction?

To create a junction node, do the following:

Once the command is initiated, select the location of the new node by left mouse clicking anywhere on the map display. Suggest a new ID and/or a description on the Junction Identification dialog box and click on the OK button to accept the ID and create the junction. The junction should visually appear at the specified location.

 Edit a Junction?
