I am using StormCAD CONNECT Edition to model the storm sewer we are designing for a highway project. We have one scenario on the project where we are running a trunk line that is a 5' x 3' RCB under a roadway that has a curb inlet on it capturing water in the sump. There is a 24" pipe coming out of this inlet and we are interested in connecting the water from the pipe to the water from the trunk line. However, we do not want to use a junction box to make the connection since they will be able to just stub the 24" pipe into the side of the RCB. How would I lay out the model in StormCAD to account for such a situation without the use of a manhole/junction box node?
To add to my colleagues' replied regarding connection of the inlet to the main pipeline - the transition element is used to model an enclosed transition between one link type/slope to another. It does not model a vertical structure and the structure loss method can be set to "none". There's a nice illustration in this article from our Wiki: Pressure Junction vs Transition vs Manhole
Another option would be to use a tap and lateral. Read about that here: How do Taps and Laterals work in the storm and sewer products?
