I'm using some recycled corrugated steel water tanks for storage at my place. When I get them they're usually full of rust holes, so the trick is to plaster the inside with a concrete mortar to make them watertight. Here's a pic of the first one in position and hooked up:

I stored the first one against a tree (I wasn't going to be using it right away) with a couple of rocks to prop it in place, and it blew away uphill in the wind one night.
I retrieved it from against the fence, and put some bigger rocks and sticks against it. A week or so later I retrieved it again from where it had fetched up against the fence on the OTHER side of the hill. After that I used 4 steel posts to fence it in place. It stayed put. ;-)
A couple of weeks ago I was visiting my parents, and loaded another old tank onto my truck to take home (these old tin water tanks are about 2m/7' high and 1.7m/6' diameter). I then had a moment of brain fade, and attempted to drive across their ramp instead of out the gate. The ramp has an "archway" over the top of it. Screeeeeech! ... and a rather battered looking tank.
On Saturday I enlisted a young neighbour to help me fasten wire netting to the inside of the two tanks, in preparation for plastering the insides with concrete (they bear a striking resemblance to kitchen colanders at the moment). That all went well, and we put them in position on the tankstand ready for concreting next weekend.
I got home at about 7:30 last night, and had my usual wander around to make sure everything was in order. Strangely, I was missing one water tank. I followed its tracks off the tank stand, up over the hill, over the fence, down the hill across the neighbour's paddock, over another fence, and finally found where it had come to rest against a big blackberry bush about 1km (2/3 mi) from where it started.
It's picked up a few more war wounds, but considering it's journey it doesn't look too bad.
Oh, and the ladder was still safely stowed away inside it.
