Water Tank Rebate

Water Tank Rebates with SA Water

Collect water and up to $1,000.


A rebate is generally not available for renovations and extensions as from 1 July 2006, because most new houses and significant extensions or additions to existing homes need to include a rainwater supply as part of the building approval process.


What does the rainwater tank rebate cover?

  • $200 for the purchase of a new or replacement rainwater tank which needs to be plumbed for use to either a toilet or all cold water laundry outlets or hot water service
  • Up to $600 for plumbing services (including services of a licensed plumber) to connect rainwater to either a toilet or all cold water laundry outlets or hot water service
  • Up to another $200 extra for additional installation measures


General terms and conditions are:

  • All rainwater tanks need to be 1000 litres or more and plumbed into at least one eligible fixture type (toilet cistern, all laundry cold water outlets or hot water service)
  • Eligible homes are generally homes for which an application for development approval was lodged before 1 July 2006
  • You must obtain a signed Certificate of Compliance from a licensed plumber indicating which eligible fixture types have been plumbed in
  • You will need to provide the original receipt when claiming the rebate for the rainwater tank and switching device.
  • Rainwater tanks and plumbing must comply with relevant Australian Standards and any local council requirements that may apply.
