Gaining approvals to connect your development to our water and sewerage network can be a complex and involved process, involving multiple professionals.
We’ve made the process more manageable by training and accrediting a large pool of Registered Certifiers who can assist you with each stage of the approval process.
They assess connection applications and prepare Certification Packages for Unitywater’s consideration. We assess these Certification Packages and issue a Decision Notice.
Our Accreditation Register lists an extensive range of Registered Certifiers to choose from, or you can find out more about Using a certifier here.
