If an elevated tank stand is not required for pressure, there are a few options for tank bases.
Concrete Slab Base
The no-compromise solution to base construction is a reinforced 100mm concrete slab. A slab can be square or round. The base should always be 100mm larger than the diameter of the tank. Prior to pouring the slab, ensure the ground has been 100% compacted. Your base will be compromised if soil has not been compacted and will affect your tank guarantee.
Crusher Dust/Sand Base
A crusher dust/sand base is considerably cheaper than a concrete slab, but may need to be augmented over time. Heavy rain falls can erode a crusher dust base and may cost you extra if it needs to be repaired.
It’s best to use treated pine sleepers, screwed together at the ends to create a retainer for the crusher dust/sand but many other materials are appropriate. Ensure base is compact and sturdy prior to laying down the crusher dust/sand. Base should be anywhere from 25mm to 50mm high when compacted. Crusher dust or sand is available from any landscape material suppliers.
Pre-Cast Concrete Slabs
A series of pre-cast concrete slabs or pavers on a sealed bed of sand makes an appropriate base for a slim cylinder tank or a tank stand.
Prepare a flat area for your tank. Clear an area that is 300mm wider than the diameter of your tank.

So there are a number of ways to make a base for your water tank. A steel tank stand designed and certified by an engineer (as are all JoJo tank stands) is required if pressure is required (and you do not want to fit a pressure booster pump). Tank stands are an advantage over tank bases on the ground as they keep the tank away from potential damage (such as fires, vehicles or other accidental bumping).
JoJo Tanks have a recommended procedure when installing tanks on a ground base:
