Rainwater tanks: Residential rebate program

The Rous County Council Rainwater Tank Rebate Program is available to eligible residential town water customers in the Rous region who wish to reduce their consumption of town water by installing a rainwater tank.

What do I need to know before deciding to purchase and install a new rainwater tank?

Program eligiblity

To be eligible for the program, the property where you rainwater tank has been installed needs to be connected to town water and be within the Rous bulk water supply area. This means, your property needs to be in the council areas of:

  • Ballina (excluding Wardell and Meerschaumvale);
  • Byron (excluding Mullumbimby);
  • Lismore (excluding Nimbin);
  • Richmond Valley (excluding Casino and land west of Coraki).

Guidelines have been developed in partnership with each of the four councils within the Rous bulk water supply area.

Am I eligible for a rebate?

To be eligible, the tank must meet the program Terms and Conditions including, but not limited to:

  • The rainwater tanks must be installed, completed and paid for between 01 July 2023 and 30 June 2026.
  • For new homes and major renovations, any tank volume or internal connection required by BASIX will not be eligible for a rebate. Tank volumes or internal connections not required by BASIX may be eligible.
  • The rainwater tank must have a minimum volume of 2,000 litres.
  • Properties that have previously received rebates from Rous may not be eligible.

Please ensure you read all of the program Terms and Conditions on the application form to ensure you are eligible.
