What do I need to consider when installing a water tank?

It is important that all tanks are installed in accordance with manufacturer's specifications. Particular attention needs to be given to the supporting base upon which the tank will be located. Every 1000 litres of water weighs one tonne and as many tanks can contain a considerable amount of water, proper base preparation is essential. This will ensure the tank does not lean or topple or cause damage to pipes and drainage lines. Additionally, tanks should not impede access for building and fence maintenance or inspection as this may lead to problems later on.


The overflow from a tank is required to be disposed of in an approved manner, so as not to cause a flooding or nuisance problem to adjoining properties. In most cases this will mean connecting the overflow into an approved stormwater system for disposal to the street gutter or to a drainage easement.
