    If you own a property that is leased, please let all future tenants know that recycled water is provided.

    What if the inspection identifies that some repairs need to be made?

    When H L Mullane undertake the inspection it is possible that they may find one or more items that need to be repaired. The home plumbing inspection is free of charge, but further plumbing work is the responsibility of the property owner to complete before recycled water is provided.

    Why do I need to use a licensed plumber?

    Property owners should only use licensed plumbers for any plumbing work. This is to ensure that no ‘cross connections’ between the drinking water and recycled water systems are accidentally made. The plumber will also ensure the recycled water system is labelled and colour-coded, and that all fittings are in place.

    Why does my recycled water plumbing have purple fittings and removable taps?

    The taps which provide recycled water have purple fittings so they can be easily identified. Recycled water is provided to flush toilets and for taps outdoors. Some homes will also have a recycled water tap in the laundry for connection to the washing machine (if this option was chosen by the property owner when the house was built).

    Removable taps are provided outside to help ensure the water is not accidently used instead of drinking water, for example when filling swimming pools or for children to play under sprinklers.

    Will the recycled water smell different to drinking water?

    You may notice the recycled water smells slightly more of chlorine, because it is more highly disinfected.

    Where will my recycled water come from?

    The new recycled water plant at the Morpeth Wastewater Treatment Plant provides recycled water to customers in Chisholm and Thornton North. The recycled water is pumped from Morpeth to the pumping station at Chisholm, where it is disinfected using chlorine before being distributed to customers.

    Is recycled water subject to water restrictions?

    Recycled water will not to be subject to water restrictions, however, we ask you to use it wisely, for example, not watering outside during hot days when more water will be lost to evaporation.

    What happens if the recycled water plant needs maintenance? Will I still have water available?


    It’s possible that from time to time the recycled water plant won’t produce recycled water. For example during maintenance. If this happens there is a backup water main connection at the treatment plant to ‘top-up’ the water supply to the recycled water network. Customers will not notice any interruptions to their water supply.

    What are my responsibilities as a property owner when it comes to my recycled water plumbing?


    It is the property-owner’s responsibility to make sure the plumbing on their property meets Australian standards. 

    For this reason, all plumbing work should be completed by a licensed plumber. 


    How do I check if there is a cross-connection between my drinking and recycled water pipes?


    The drinking water and recycled water pipes at your property must be completely separate from each other. Hunter Water’s contractor, H.L. Mullane, inspected all homes to ensure this was the case and there are no cross connections on your property.

    If you have any plumbing work completed we advise you to complete a simple self-check to make sure there are no cross-connections.

    We suggest you complete this cross-connection check once a year.

    1.  Turn off your drinking water meter. Leave the recycled water meter (purple) on.

    2.  Slowly turn on each hot and cold tap in the laundry, sink, bath and shower, one by one. Each tap should run dry after a very short time (less than thirty seconds). If a tap continues to run, it may be attached to the recycled water supply. This is called a cross-connection, and you should contact Hunter Water urgently. Turn off each tap.

    3.  After all taps have run dry, flush all toilets. Each toilet should refill normally as they are connected to the recycled water supply.

    4.  Disconnect your washing machine and run the tap it was connected to. If it runs dry, your washing machine is connected to drinking water. If the tap continues to run, it is connected to recycled water. Some property owners elected to have their washing machines connected to recycled water – this is fine.

    5.  If you would like to check your dishwasher, bidet or any other device, test it now. These appliances should not run because the drinking water has been turned off (see step 1). If they do run, they are connected to recycled water and you should call Hunter Water immediately.

    6.  Now go outside and test each tap. The outside taps connected to drinking water should run dry. The outside recycled water (purple) taps should continue to run as normal.

    7.  Make sure all taps are turned off. Slowly turn your drinking water meter back on. Please note to turn all taps on slowly next time, as there may be air in the pipes for a short time.
