A rainwater tank gives you your own water supply. You’ll save on your water bills, as well as help to:

  • reduce demand on the city’s main water supplies and network infrastructure
  • defer the need for new dams
  • reduce the size of water distribution pipes and the energy needed to operate supply systems
  • reduce stormwater run-off that can cause local erosion and flooding
  • improve water quality in local waterways, the river and the bay

The Council recommends you use your tank water for:

  • toilet flushing
  • watering the garden
  • washing the car
  • cold water washing machine taps

Using a 3,000 litre tank for toilet flushing, washing machine and outdoor use will cut the average Brisbane household’s use of mains water by 11%. Your local plumber, builder or rainwater tank supplier can give you information about installing a rainwater tank at your home. Before installing your tank, you may need to obtain plumbing and/or building approvals to make sure it meets plumbing and building standards.
