Recycled water

Our Recycled Water Treatment Plants use a multi-step process to make the wastewater safe to use again. There are National and NSW State Government Guidelines for the production and use of recycled water that we need to follow.

The steps include:

• Ultraviolet Light Disinfection to kill bacteria and viruses
• Straining to remove larger contaminants
• Microfiltration to remove any parasites
• Reverse Osmosis which gets rid of chemicals and salts
• Another round of Ultraviolet Light Disinfection to destroy organic chemicals
• Sodium Hypochlorite Disinfection which adds chorine, and finally
• Mineralisation to add calcium back into the water to balance the pH levels.

Recycled water comes to you through purple pipes that are completely separate from our drinking water.

You’ll know if you have access to recycled water at your property if you have a purple water meter at your place, or your toilet, garden and laundry taps are purple.  All taps should have signs that say 'Recycled water – do not drink. These taps will also turn in the opposite direction to your other taps, and you will have recycled water charges on your water bill.

Recycled water is not suitable for drinking.

If you live in the new parts of Thrumster, Lake Cathie, or Bonny Hills, chances are you will have purple pipes at your place. We’re still working through all the checks and balances to get you recycled water, so at the moment your purple pipes are carrying drinking water. Don’t worry – we’ll let you know before we turn on the recycled water.

From July 2022 residents have be charged the recycled water charges at 80% of potable water.

Recycled water isn’t available for all residents yet. We’re still building the infrastructure to carry the water to residential areas.

Our Recycled Water Treatment Plant is located at Hindman Street in Port Macquarie. We can make up to 2 mega litres of recycled water each day – this is around 10% of the average daily demand on our drinking water supply in Port Macquarie alone and almost enough to fill an Olympic sized pool!

There are many regulatory checks and balances council needs to undertake to commence supplying recycled water to your house. We have almost completed these for Lake Cathie/Bonny Hills and are aiming for October to be supplying in these areas. We still have a significant number of regulatory checks to conduct in Thrumster and we hope to be supplying in this area by June 2024.
