Recycling & Reuse

Recycled water from the Kurri Kurri WWTW is used for:

  • grit and screening washing
  • general washdown at the WWTW
  • irrigating the grounds.

One of the maturation ponds from the previous trickling filter plant has been converted to an effluent storage pond, and Kurri Kurri TAFE pumps up to 400 kilolitres of effluent per day from this pond for irrigation.

Unused effluent is discharged to Swamp Creek, where the Kurri Kurri Golf Club extracts up to 370 kilolitres of treated effluent per day from Swamp Creek immediately downstream of the discharge point for irrigation.

As effluent reuse is primarily for irrigation, demands can be much lower during winter due to increased rainfall.

Continuous biosolids production is provided at the Kurri Kurri WWTW and all biosolids produced are beneficially used for mine rehabilitation or pasture improvement on broad acre farming properties.

Hunter Water recycles approximately 5091 megalitres per year. Learn more about our recycling and reuse initiatives.
