How does the program work?
This one-off rebate is for the purchase of your rainwater tank. It is calculated by the volume of the tank(s) installed and how the water is used. Higher rebates are offered for larger tanks and those with internal plumbing to laundry, toilets and/or hot water*.
- Standard rebate pays up to a maximum of $2,000
- Low-income households—50% extra to the standard rebate up to $3,000 for applicants who hold a Commonwealth Health Care Card or a Pensioner Concession card
- Multi-unit dwellings—an additional $500 for flats, units and apartments with the rebate based on the number of connections to a maximum of three (3), and amounting to a maximum of 20c per litre of tank size is paid to the body corporate for tanks installed on common property
