Greywater is generated from the bath, shower, wash basin and laundry. It can be diverted for use on lawns and gardens. Kitchen greywater is not suitable, as grease and oil from the kitchen can clog up pipes and pumps.

Greywater is a great way to save water around the house and it’s not subject to water restrictions. Here are some tips for using greywater safely and effectively:

  • Take care not to keep watering the same area – it can affect soil and can cause plants to die.
  • Be careful when using greywater on native plants.
  • Don't use greywater on edible parts of vegetables or fruits.
  • Make sure greywater does not enter swimming pools or flow into neighbouring properties.
  • Avoid bad smells or damage to plants by restricting use or moving the outlet.
  • Keep away from children's play areas.
  • Greywater can’t be stored on a property in rainwater tanks or other containers as it is a health risk.
  • Always wash your hands after using greywater.

For more information about greywater and the things you need to know before you use it, read the 'Gardening with greywater' brochure on the Department of Natural Resources and Mines(DNRM) website.
