Reported system CA at the outfall element is not correct

Product(s): StormCAD, SewerGEMS, CivilStorm
Version(s): V8i, CONNECT Edition
Area: Output and Reporting


The reported "System CA" at the outfall element is not correct and appears to be double the expected value.


This is a known issue: Defect reference number #333602.

There are two workarounds for this issue, to correct the value of system CA at the outfall; as follows.

  1. Open the calculation options for the scenario and set the property "Include Conduit Flow Travel Time in Design" to False. When you compute, system CA at the outfall will be correct.
  2. You can also simply do an analysis calculation after your design run in order to report the correct system CA at the outfall.
