What is accreditation and certification?

Unitywater now uses Accredited Entities and Registered Certifiers to assess applications to connect developments to our water and sewerage network.

Accredited Entities are responsible for the work of Registered Certifiers, providing them with the right support and oversight to fulfil their obligations.

As a Registered Certifier, you become authorised to submit Certification Packages to Unitywater for approval. This involves certifying that engineering designs and constructed assets comply with the relevant approval requirements and design standards.

All applications to connect to non-trunk infrastructure will need to go through an Accredited Entity.

How it works

Individuals and businesses can apply to become an Accredited Entity, and individuals can apply to become a Registered Certifier. We provide free training to approved candidates.

You can become certified in one or more of three categories: Minor Connection Certifier, Major Connection Certifier or Construction Certifier.

Once registered, your details are listed in our online Accreditation Register so developers can easily find your services.

To find out more about what’s involved, download the Unitywater Accreditation and Certification Manual.
