Hi Olive, here we have all types of tank stands for rain water tanks due to the drought. When I was little , everyone had one in their backyard. My father built his own from old railway sleepers. They are not so common in New Zealand as they have a good annual rainfall. Here are the types you can get:Concrete Slabs,corrugated steel ring filled with crusher dust,crusher dust base with support edging, precast concrete slabs and Timber and steel tank stands.
