Inner West Council Marrickville's Rainwater Tank Incentive Scheme – a workshop and rebate program – is available to all rate payers, residents and businesses in the local government area. It is funded from the Marrickville Stormwater Management Service Charge.

How does the program work?

Council provides you with everything you need to know about rainwater tanks from choosing the right tank for you to how to claim rebates.

Council has offers the following rebate based on the volume of the tank(s) installed and how the water is used. Higher rebates are offered for larger tanks and those with internal plumbing to laundry, toilets and/or hot water*.

  • Standard rebate pays up to a maximum of $2000.
  • Low-income households – 50% extra to the standard rebate up to $3000 for applicants who hold a Commonwealth Health Care Card or a Pensioner Concession card. 
  • Multi-unit dwellings – an additional $500 for flats, units and apartments with the rebate based on the number of connections to a maximum of three (3), and amounting to a maximum of 20c per litre of tank size is paid to the body corporate for tanks installed on common property.
