You can request minor changes to existing water or sewerage infrastructure by following our application process.
Unitywater approves and undertakes the work, but you must pay the cost of any changes you request.
Important note for water and sewerage alterations
If your alteration is part of a larger construction or development project then you do not need to apply for a separate alteration. You are able to request any alterations as part of your development application.

Changes to existing water meters
You may ask us to:
-
convert your meter from above ground to below ground
-
raise or lower your meter box
-
move your meter horizontally
-
install a lockable valve next to your water meter
-
test or replace your water meter (the cost of this is refunded if meter is found to be faulty).
To request any of the above, please submit the following application via the Development Portal.
Submit a Connection Services Application
To increase the size of your standard metered water service connection to a size greater than 25mm, this is to be applied for via a Unitywater Accredited Certifier. The Accreditation Register lists Registered Certifiers who will prepare, assess and submit your application (Certification Package) to Unitywater.
- Upon approval to increase the size of your standard water service connection, you will need to submit a Development Works Application via the Development Portal.
Please include the following with your application form:
- the lot and plan of your property
- the owner’s written consent
- for water meter relocations - a dimensioned locality plan showing your preferred meter location
- for meter size reductions - a hydraulic or certifiers certificate.
If you need help locating your water meter you can check our infrastructure map. You can also request to have someone locate it for you, but you will be charged for this service. Please view our prices.
As a business can I reduce the size of my meter?
You can contract a licensed plumber to complete a hydraulics review of your metering arrangements. A hydraulics review assesses a property’s water use requirements to determine if the property can downsize to a smaller water meter, and therefore pay lower access charges.
If you are able to downsize your water meter(s), you will need to submit a Connection Services Application via the Development Portal, along with a copy of the hydraulics report.
Submit a Connection Services Application
Please note: downsizing your water meter will incur a cost.
Your business can also install water efficient devices and appliances to help to minimise both sewerage and water usage charges on your bill.
