The installation of rainwater tanks requires the same approval process as installing reticulated town water supply unless:
- the tank is not connected to any other devices and,
- the water collected is used only for irrigation.
Irrigation is defined as water used only for garden, lawn, nursery and agricultural uses such as growth, leaching, cooling, treating, humidifying, frost protection and replenishment of soil.
The installation of a rainwater tank for the purpose of irrigation only does not have to be carried out by a plumber or licensed person, but consideration should be given to a number of factors including design and location so that the tanks:
- maximise the capture of rainwater from the roof
- minimise any visual impact on the neighbours
- do not detract from the outdoor space around the residence
- are of a colour and finish that complements the existing building(s).
It is preferred that tanks be located so they are not in front of your dwelling and do not affect the amenity of your neighbours.
Rainwater can be used for drinking but Council recommends a thorough maintenance program to be adhered to. Further information on private water supply click here.
Where a reticulated water system is available, Council does not recommend the use of rainwater for human consumption, bathing, food preparation and utensil washing.
When a cross-connection with rainwater and town water supply is required, please contact Council's plumbing section for the advice on the types of backflow protection and other issues.
A licensed plumber needs to be engaged for any regulated work such as installing rainwater tanks for any other use than irrigation.
