Waterwise WA Rainwater Tank Rebate

In June of 2020, the Water Corporation announced its Rainwater Rewards program, encouraging customers across WA's South West to install new rainwater tanks, or perform much needed maintenance on existing tanks.

Can this fund be used for existing water tanks?

The Waterwise WA Rainwater Tank Rebate is valid for certain Perth towns in the Great Southern and South West regions, and you and find a list of towns eligible for rainwater tank rebates on the Water Corporation’s website.

Eligible residents can apply for one of the following offers:

  • Up to $1000 for a new rainwater tank larger than 2000L that is plumbed.
  • Up to $500 for the plumbing of an existing rainwater tank
  • Up to $500 to replace an existing plumbed in rainwater tank

The Water Corporation states that  by installing a rainwater tank, you can save up to 20% of your household water use each year, and a 125m² home in the South West can harvest up to 51,000 litres of water each year – meaning you’re likely to want a tank larger than 2000L if you have the room!
