I had two areas 4'x4' on each side poured 30" deep for lift pads on both sides. Do your self a favor put drains in and my biggest PIA is no running water in the shop! Even something to hook a hose up outside I would take.
is rain water collection legal where you're at? you could hook that up to your gutters and a sink inside, then plumb the grey water into another drum.
