Water Tank Rebates in Victoria (VIC)

The Water Smart Gardens and Homes rebate scheme rewards residential customers connected to a mains water supply for purchasing water-saving devices and services, thereby reducing their water consumption.

Households who purchased and installed a rainwater tank from 1 January 2007 are eligible for a rebate of up to $1000. Rainwater tanks can save up to 40,000 litres per household per year. The rebate is based on the size of the tank and requires the tank to be connected to toilet and/or laundry facilities as follows:

  • Rainwater Tanks, 2000 - 4999 litre capacity, connected to toilet and/or laundry - $500 rebate
  • Rainwater Tanks, 5000+ litre capacity, connected to toilet or laundry - $900 rebate
  • Rainwater Tanks 5000+ litre capacity, connected to toilet and laundry - $1000 rebate

Householders who have already claimed a tank rebate prior to 1 January 2007 are still eligible for a rebate if they purchase an additional large tank connected to the toilet and/or laundry. The large tank rebates can be paid via a one-off Electronic Funds Transfer (EFT) or by cheque and should take around 10-12 weeks to process.

The existing $150 rebate for tanks 600 litres or larger not connected for indoor use will still apply, as will the $150 tank to toilet connection for new small tanks (600 L to 1999 L) and existing tanks. These two $150 rebates will continue to be credited to your next water bill. The Water Smart Gardens and Homes Rebate Scheme is administered by the retail water corporations on behalf of the Victorian Government, in partnership with the Department of Sustainability and Environment.

Water Tank Rebates in Australian Capital Territory (ACT)

Rainwater Tank Rebate & Internal Connection (only) Rebate

The ACT Government offers rebates for the installation of eligible rainwater tanks with an internal plumbing connection to inside the home (for example to the toilet or washing machine) on properties connected to ACTEW Corporation's water supply network.

The program recognises that maximum benefits from installing a rainwater tank, in terms of water saving and stormwater protection, are generated when the tank water is used for internal purposes such as toilet flushing and clothes washing as well as for garden watering. This provides a way for tank water to replace mains water all year round - internally during cooler months when the garden doesn't need much water, and outside in the garden as well in warmer months - thereby increasing the amount of rainwater that can be harvested and used.

While there are no additional charges or taxes on the collection of rainwater, the ACT Government understands that initially there is a cost associated with plumbing the tank water to use inside the home, and that is why the rainwater tank rebate program specifically rewards those residents who are prepared to make that extra investment to maximise the water savings from the use of their tanks.

Properties which are not eligible rebates under the scheme

Development on blocks where rainwater tanks are proposed in order to satisfy lease and development conditions or requirements contained in the relevant Precinct, General or Development Codes (following the introduction of the new Territory Plan) are not eligible for rebates under this program. This generally includes all housing in new estates. Redeveloped blocks, extensions in excess of 50% of the original area and multi-unit developments where rainwater tanks are included in the development proposal for the dwelling or where they are proposed in order to satisfy a condition of development approval, do not qualify for a rebate.

You can obtain details of the lease and development conditions for your block from the ACT Planning and Land Authority's Lease and development conditions register search website, or by calling the Duty Planner on 6207 1923.

Rebate details for installations on or before 31 January 2008

Rebate details for installations on or after 1 February 2008

For more information call 13 22 81.

Residents need to look at their particular circumstances when considering the cost and benefits of installing a rainwater tank and internal plumbing. The ACT Government's Rainwater tank guidelines for residential properties in the ACT (2.3MB) provides information to assist.
