Using recycled water

Discover how recycled water can be used around your property.

Recycled water is wastewater that has been collected and treated so it can be reused for a variety of non-drinking purposes.

After undergoing an intensive treatment and cleaning process at a recycled water plant, the water is piped back as recycled water via purple-coloured pipes to be reused. Learn more about how recycled water is treated on our Treating recycled water page.

By using recycled water you:

  • reduce our reliance on drinking water supplies
  • save money because recycled water is charged at the lowest water rate no matter how much you use 

Recycled water usage is exempt from Permanent Water Saving Rules.

Recycled water at your property

Recycled water is only available on properties where purple taps and pipes have been installed. The purple tap can be found outside your property.

Purple taps on your property must have a sign on them that says they are recycled water taps and should not be used for drinking. It is your responsibility to maintain this signage.

Recycled water usage is charged the same as the cheapest level of drinking water. You will also see a recycled water service charge on your bill which covers the cost of the additional infrastructure required to supply the recycled water.

Storage of recycled water on residential properties is not currently allowed.

How recycled water is used

After treatment, recycled water is classified into Class A, Class B and Class C. Each class of recycled water has specific uses.
