Preparing a Connection Application?

All eligible connection applications will need to be prepared and submitted to us by a Registered Certifier.

A Registered Certifier helps make the approvals process easier by preparing, assessing and submitting your applications for Unitywater's approval.

Our Accreditation Register helps you find the right Registered Certifier to assist with your application. We will then assess the Certification Packages and issue Decision Notices.

We only accept connection applications prepared by a Registered Certifier.

Please note: if you are seeking connection of a single dwelling then you will need a standard connection.
