Invalid Geometry [ Who makes the plaid blue coat Jesse stone wears in Sea Change? Manhole steps, most often made from concrete or plastic, are steps on the walls of the manhole for personnel to use to safely climb down when inspecting, cleaning or repairing. The Pipe Crown Cannot be above the Rim Elevation of the Node - the program will raise the Rim Elevation when this happens and print a warning in the rpt file. Also keep in mind that SWMM assumes each junction is a standard 4-ft diameter manhole with no cone top unless you tell it differently. It is not unusual to set the ground and rim elevation to the same value. lha (Civil/Environme)is correct. To fix this, I've used the structures with no frame, which has a lower minimum depth than the structures with frames.
