For each tenancy to be separately metered, the existing meter would remain at the property boundary as the master meter, with each tenancy individually metered via subtract meters.

To apply, the Owners Corporation must submit a Water Service Application with a hydraulic plan that is prepared by a suitably qualified plumber or hydraulic consultant.

The following requirements apply:

• All flow through the master meter must also be metered through subtract meters, such that the sum of flow through the master meter minus the sum of flow through the subtract meters is zero. 
• The hydraulic plan must clearly confirm that there are no connections between the master meter and the subtract meters (for example an unmetered connection to an external hose tap). 
• The hydraulic plan must show the current pipework configuration and any proposed alterations on the privately owned component of the properties’ water service to demonstrate that these alterations are able to be carried out. Please note: plumbing and drainage fees apply for internal plumbing works. 
• Council's Smart Metering Devices must be installed on the master and all subtract meters. Learn more about Smart Metering.

The Owners Corporation nominated plumber will be responsible for the supply and installation of the subtract meters. The subtract meters will need to be compatible with Council’s smart metering devices (i.e. Elster meter).

If the existing main meter servicing the property is older than 15 years it will be replaced by Council as part of our meter replacement program. If a larger water service is necessary, the plumber or hydraulic consultant will need to indicate on the hydraulic plan the required size and charges may apply. Please note that any meter service greater than 25mm will require a backflow prevention device to be fitted to the customer's side of the water meter. The customer will be responsible for the installation of the device and associated costs.
