Understand what a certificate to connect is

A certificate to connect is an official approval issued by Council that authorizes connection, disconnection, upgrade or change to its Three Waters network water supply, wastewater, and stormwater systems as required by a development using only a prequalified contractor.

It is typically required for:

• Service connections for new developments or dwellings
• upgrades or relocations of existing connections
• permanent disconnections (for example, for demolitions or decommissioning)
• Temporary disconnections during construction or maintenance

Process
  1. Application: Developers or property owners submit an application to the council, detailing the type of connection, chosen contractor from the pre-qualified list, submit required work pack and pay associated fees.
  2. Development Contribution: Developer completes payment for development contribution as required.
  3. Approval: The Council reviews the application, checks compliance, and issues the certificate.
  4. Execution: The physical connection is carried out by a council pre-qualified contractor.
  5. Inspection & Sign-off: The Council inspects and signs off the work to confirm compliance before the connection work becomes operational.
