Domestic rainwater tanks
Around 55,000 litres of water could be collected from a 100 square metre roof area and used to supply part of your household's water needs.
A Waterwise Rebate of up to $600 is available for the purchase and installation of new tanks for domestic use.
The rebate is available for one rainwater tank per household.
Tanks with a capacity greater than 600 litres that are not plumbed in are eligible for a rebate of $50.
Tanks with a capacity greater than 2,000 litres are eligible for a rebate of up to $600 or 50 per cent of the purchase and plumbing in cost (whichever is the lesser amount) if they are plumbed in by a licensed plumber for use in your toilet and/or washing machine when installed.
| Tank Capacity | Rebate |
| 600 litres or greater unplumbed | $50 |
| 2,000 litres or greater and plumbed in for toilet and/or washing machine use | $600 up to 50% |
