AutoCAD Civil 3D - Stormwater

[#1]

I need to model a diversion manhole in a storm sewer system.  The diversion will take X cfs from the system and send it to a water quality treatment facility.  After leaving the WQ facility, it will be returned to the storm sewer system at the next manhole downstream.

I tried in Hydraflow but it doesn't look like diversions are possible.  Thought about modeling up to the diversion manhole and taking that data into some other program, and then coming back into a second Hydraflow model that handles the downstream bit.

I haven't seen any responses on this yet.  Is there not a solution?

you can model this using the flow diversion feature in SSA, see image below. read up on the flow diversion in the SSA user manual, to properly set up the "diverted" flow and the "remainder" flow. good luck!
