I just stumbled across ten of these round containers. I believe them to be around ten gallons in volume and they have a clamp-lock lid with a relief valve. I have done a bathtub test, with no leakage. I know I have a number of uses for these and figure you could as well. If you think you can use one, I can do them for $50 shipped (shipping is the main cost, and I can't do any discount for multiples) in CONUS, Canada and AK/HI shouldn't be much more.
