Applying for treatment plant approvals

If you're a treatment plant manufacturer, you need to understand the requirements and processes for treatment plant approvals.

The requirements for treatment plant approvals are under the Plumbing and Drainage Regulation 2019. The regulation includes provisions about:

  • transfer of ownership
  • amendments of treatment plant approvals
  • reporting and inspection powers where the chief executive considers that a particular treatment plant either:
    • is susceptible to systemic failures
    • may not be operating in accordance with the approval.

See the documents to accompany an application for a treatment plant approval.

New approvals

On-site sewage treatment plants

A new application relating to a secondary on-site sewage treatment plant must comply with Australian Standard AS1546.3:2017 (Secondary treatment plants) and the conformity assessment requirements.

Greywater treatment plants

A new application relating to a greywater treatment plant must comply with Australian Standard AS1546.4:2016 (Domestic greywater treatment systems) and the conformity assessment requirements.

Renewing existing approvals

If you already have approval that expires before 1 January 2021, you can apply to renew your existing approval before it expires. Your treatment plant must comply with the Queensland Plumbing and Wastewater Code (2017). The treatment plant approval would then remain valid until 1 January 2024.

If your current approval expires after 1 January 2021 and you want a renewal, your treatment plant will need to comply with the current Queensland Plumbing and Wastewater Code (2019).
