How recycled water is used

Recycled water can be used for different purposes such as irrigating:

  • parks
  • sports fields
  • crops.

Types of recycled water schemes

Recycled water use is categorised into two schemes, depending on the level of exposure to the public:

  • low exposure
  • high exposure.

Low-exposure recycled water schemes

Common low-exposure uses of recycled water include:

  • irrigation of:
    • public open spaces (such as playing fields and parks)
    • pasture and fodder crops
    • heavily processed food crops
    • non-food crops
  • dust suppression on mining or construction sites.

To help you meet your water quality requirements for low-exposure use, you can use the spreadsheets below.

High-exposure recycled water schemes

High exposure recycled water schemes include supplying recycled water to:

  • increase a supply of drinking water via a source supply (eg. a dam)
  • support a development by way of a dual reticulation system
  • irrigate minimally processed food crops.
