Rainwater tanks can store water run-off from your roof for use around the home or garden. Installing a rainwater tank, together with other household water saving devices, can reduce your household water use by up to 25 per cent - saving you money on water bills and conserving potable water.
If you're building a new home, installing a rainwater tank can help you achieve the minimum regulatory requirements of the 6 Star Standard. To meet the 6 Star Standard with a rainwater tank, it must be installed in such a way that it receives the rainfall from the minimum catchment area of 50 square meters; and have a minimum capacity of 2000 litres; and be connected to all toilets in the building for the purpose of sanitary flushing.
Rainwater can be used for flushing your toilet, watering your garden or for use in washing machines. You should test rainwater for potability (drinking quality) before you consider drinking it.
Frequently asked questions about rainwater.
The best reason for using rainwater is that it is free and, if not captured in a tank, it is a vital resource that literally goes down the drain. Rainwater tanks are an increasingly common feature in gardens around Australia. Despite the initial cost, installing a rainwater tank can save you money by reducing your water bill in the long-term, and help save the environment.
Diverting stormwater runoff from your roof for household uses such as toilet flushing also reduces polluted inflows to our waterways.
