Containers for storing RO water/aged water

I use large plastic barrels that they use to transport bulk quantities
of olives. They hold 200 litres and have a screw on lid. I get them
locally for AU$25 each. You can also drill holes in them to directly
attach PVC fittings. A friend of mine uses them as large canister
filters for his 8' by 3' by 2'.
