Water Tanks

A rainwater tank does not require a building permit provided that the tank is a small proprietary type of steel or fibre glass tank with a height not more than a standard fence height i.e 1.8m. Indicatively the tank is less than 5000 litres capacity. The location of the tank should be in the rear yard of a property and not be visible from the primary or secondary streets.

The base of the tank is to be located directly on the ground or supported by a manufacture designed tank stand not exceeding 300mm in height. For all other situations a building permit would need to be obtained prior to installation.

Information on the use of the water contained in rainwater tanks can be obtained from enHealth by the below website link.
