Well, there is what I refer to as my grandfather's septic, which is the most classical one that most people think of. They sit in there and the solids separate. The resulting liquid is passed on and eventually sent to a field. In the original designs those are all just gravity flow. So gravity can fill the water from the house into the tanks; then from the tanks into the field, and that's what I refer to as a grandfather septic. It's what most people think of when they think of a septic.
Beyond that, however, there are systems that utilize pumps, floats, and alarm systems to advise when bad conditions have occurred. The systems use treatment technologies, such as either blowing air into the sewage or trickling technologies (somewhat like water trickling over rocks in the stream); we trickle sewage over gravel rocks or sometimes even on artificial media. We treat the wastewater that way.
With the disposable method it could be sprayed on the ground through special sprinklers or it could be introduced slightly below the ground through sub service systems. So there are just a whole myriad of solutions.
