Like into your existing City Sewer line from under your house, like this?

Do does this need to be on DL and have to semi-stealth dump (not just parking that bad dude up next to the house).

What sort of Permit etc would be needed to run an RV dump (and Power/Water) to a pad about 120ft from main house? (assuming the grading works out, might need to pile up some dirt to raise the pad or "board walk" for the RV.
