Water Tank Rebate

Water Tank Rebate - Sydney Water: Residential

A rebate of up to $1,500 is available to Sydney Water customers who install a rainwater tank before 30 June 2011. Rainwater tanks installed as a condition of BASIX certification are not eligible for a rebate.

Properties outside of Sydney Water's area of operations can apply for a rebate through the Department of Environment and Climate Change.

There are two parts to the rebate (both parts must be completed before claiming the rebate):

  1. A tank capacity rebate - for the size of your rainwater tank
  2. An internal connection rebate - for connecting your rainwater tank to a toilet(s) and/or washing machine.   
Tank(s) capacity Rebate*
2,000 - 3,999 litres $150
4,000 - 6,999 litres $400
7,000 litres and above $500
Internal connections Rebate*
Rainwater tank connected by a plumber to toilet Additional $500
Rainwater tank connected by a plumber to a washing machine Additional $500

Note - Only one rebate will be paid per property over the life of the program. The total rebate cannot be more than the total cost of the tank and installation.

If you bought and installed a rainwater tank between 20 October 2002 and 30 June 2007, you are eligible for the previous rebate amount of up to $800.
