About the Set Sump Depth Structure Rule

This rule sets the sump elevation of junction structures based on the user-specified parameters and the invert elevations of pipes attached to the structure.

When this rule is applied, the elevation of the inside bottom (sump) of the structure is calculated by subtracting the user-specified sump depth from the elevation of the lowest invert in the structure.

Parameter

The following parameter governs the behavior of this rule:

• Sump Depth. Specifies the sump depth, or the vertical distance from the invert of the lowest pipe attached to the structure to the inside bottom of the structure.
• Control Sump By. Specifies the method of resizing the current structure. Select either Depth or Elevation.
