Important customer update

We're improving how we manage billing issues and potential privacy incidents, including actions we're taking as part of our enforceable undertaking. Learn more.

During the Victorian State election caretaker period (3-28 November 2026), we'll only publish web content and updates that are in line with the caretaker conventions.

Life support machines and priority support

If you’re a customer with additional needs, we can give you priority notice when your water supply is interrupted.

We can offer you additional support if:

  • you use a life support machine at home
  • someone in your household uses a life support machine
  • you need a continuous water supply for other reasons.

What kind of support do we offer

We’ll contact you directly:

  • when there is an unplanned interruption to your water supply
  • at least four days before a planned interruption to your water supply.

You may also be able to get a life support concession (for haemodialysis machines). 

How to register your household

Generally, your health service provider will tell us about your situation. Your health service provider could be your doctor, nurse or hospital social worker.

If you’re not sure whether your health service provider has registered your household for priority support, contact us:

  • call 13 44 99. Note: we’ve temporarily extended our call centre hours. You can reach us by phone Monday to Friday 8am to 7pm, and Saturday and Sunday 9am to 5pm (closed public holidays).
  • email lifesupport@gww.com.au.
