First you need to decide how automated you want it to be, just a push of a button or if you just want to open a valve and drain the sump the refill it via a pump.
If your thinking about tapping into your sewer then your going to have to have a valve or put in a stink trap. I personally would put in a stink trap.

Yeah definitely some protection here so you don't somehow get smell or worse backflow, parasites, etc.
