When a 23,000 litre (5,000 gallon) water tank starts to rust you end up with a big object to dispose of. It is heavy, it is awkward to handle, it is a dead weight that is always in the way.
We mulled over what to do with ours for a long time before inspiration struck. Vegetable gardens, just like those over-priced ones you see in the gardening centre!
We had a cute idea with concentric circles of garden beds which sounded exciting until we realised that any attempt to bend corrugated iron wouldn't work and would be a waste of time.
I have to acknowledge that my wife had the idea we finally went with: to cut the tank into sections and rejoin them.
This is how we turned our old water tank into 6 boat shaped vegetable garden beds.
