Finding drain pipe daylight locations

Here is a challenge I'm needing to solve.

 

I need to rough in a drainage pipe network that connects several structures around a site. The pipe inverts need to be 6.5' below the finished floor of each unit and must maintain a minimum 2% slope. The network needs an outfall at some undetermined point on the site. The pipes must follow some existing roads, so they are not interconnected directly to each structure.

 

How can I go about determining the potential outfall locations?

Start with the worst case scenario: the lowest unit. Go down your depth, then start sloping down. Maybe make a surface sloping down 2% all directions for a rough idea. Then do a mindistbetweensurfaces to your original ground to see if you have any outfalls.

Thanks for replying. Starting at the lowest unit seems to make sense but the furthest unit is also critical if there is not enough drop at 2% for it to daylight.

 

After spending some time on this I don't see any other way than trial an error.

I'd say you're right. Too many parameters and options to totally automate.
