The Conditions of Connection are imposed under Section 145 of The Water Act.

Planning to build near Barwon Water assets

Any construction within one metre of a Barwon Water asset (eg: pipeline) or in a Barwon Water easement is defined as a build over.

To build near our assets, you must first obtain build over consent.

Developers who require specific water requirements will also need to apply.

Connecting in an unserviced area

If you would like to connect in an area not currently serviced by Barwon Water, contact us to find out more about servicing options. We recommended you ask your plumber, builder or project manager to assess servicing options prior to applying.

You might be able to connect via a new private connection, or a private connection owned by another party. You would need to obtain consent from the other owners and enter into a supply by agreement.

A submeter is a meter that is installed in a multi-unit development (eg: units, townhouses, apartment complexes, commercial buildings). A submeter allows multi-unit property owners to measure individual water use.

We recommended you have your plumber assess options prior to making an application.

You need to apply to Barwon Water to have submeters installed.

Step 3: Review the application

Once an application has been submitted Barwon Water will review your application. We may contact you for further information.



Step 4: Make payment

Payment is usually made online as part of the application to connect.

Further costs may be charged if additional work is required (e.g. asset protection for a build over or a supply by agreement).



Step 5: Notify Barwon Water to fit meters

As part of the plumbing works at a property, your plumber will make provision for a water meter (and a recycled water meter, in dual pipe subdivisions).

Your plumber will then contact us to organise to fit meter(s).



Step 6: Submit a drainage plan

When work is complete, a drainage plan is to be submitted to us. A drainage plan shows the basic layout of a property and the location of sewerage pipes and the connection to the sewerage system.

Barwon Water is the custodian of all drainage plans in our region. If works are required in the future, these plans may be required.
