Preparing a Connection Application?

Unitywater has a single streamlined connection approval process for non-truck infrastructure to ensure connections to our water and sewerage network are quick and consistent.

We use Registered Certifiers who can be found on our Accreditation Register, and they will help you get your developments to market quicker, with greater control over the time and cost of the application process.

After receiving a Certification Package from a Registered Certifier, we’ll issue a Decision Notice within 10 business days from receipt.

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.

How certifiers help you

Registered Certifiers are external providers that have been fully trained by Unitywater to:

While Unitywater issues the final Decision Notice, Registered Certifiers help with:

  • Assessing developers’ connection applications
  • Preparing Certification Packages, including drafting Decision Notices and Infrastructure Charges Notices for Unitywater’s approval
  • Inspecting works and certifying that the as-constructed condition of the assets meet prescribed standards
  • Preparing requests for Provisional Certificates of Completion and Certificates of Completion
  • Monitoring compliance with conditions of Infrastructure Agreements and Water Connection Approval Agreements and informing us of any non-compliance.

Types of certifiers

Depending on the size, type and complexity of your development project you will need to choose the right certifier for your project You may need to engage a:
