What happens next

If we approve your consent application, your system needs to be installed as per the approved building and resource consent documentation and conditions.

You will also need to apply for a Code Compliance Certificate (CCC). This is to ensure that the works carried out comply with the building consent and Building Code.

Before you apply for a CCC

The registered drainlayer that installs the system will need to provide:

  • a producer statement-construction (PS3) as soon as possible after the installation work has been completed
  • an as-built site plan showing the location of all elements of the system.

The engineer who is registered with us, needs to:

  • verify the work is completed in accordance with the approved design
  • provide a producer statement-construction review (PS4) as soon as the installation work is completed.

You will also need a copy of the maintenance agreement (from the professional who will be doing ongoing maintenance of the system).
