Watering CanQuick guide to Greywater

Every day we produce greywater. This is the wastewater from our washing machine, laundry tub, hand basins, showers, baths and spas. The good news is, untreated greywater can be used on your garden and its use is not restricted under the ACT’s Water Restriction Scheme.

Collecting greywater can be as simple as keeping a bucket in the shower to collect the cold water before the warm water begins to flow. You can also divert greywater from your washing machine or basins. Approved larger scale greywater treatment systems are available to purchase.

For guidelines on greywater use in the ACT, visit the Think water, act water website or the ACT Health website.

DO’s

  • Only use wastewater from baths, showers, hand basins and washing machines (preferably the final rinse water).

  • Wash your hands following watering with greywater.
  • Stop using greywater during wet periods.

  • Don't water vegetables with greywater if the crop is to be eaten raw or uncooked.
