For septic you can bury a 55 gallon plastic drum in the ground. Either drill holes near the top or run a fill line from it.

This would certainly not be up to code in (most) places. In many areas, the state environmental protection agency would care very, very much, and show how much they care by imposing very substantial fines and penalties.
