Need to know about wastewater approval processes in QLD?

When it comes to wastewater in Queensland, we have a few different processes and procedures for the installation of treatment facilities on properties around the state. From small homes to large-scale areas and anything in between, wastewater treatment plants are used to assist those who are not connected to municipal sewerage arrangements in the treatment of sewage from their home.

There are various wastewater systems that you can install on your property, however, each and every arrangement has a range of approvals to be obtained before they can be installed. This is to ensure that you, your household, your neighbours and the environment will not be negatively impacted by the system, which can have a huge range of issues if it isn't the correct system for your needs. If you have any questions regarding wastewater systems, give Express Wastewater a call at 1300 722 517 and we will be happy to discuss your queries.

Wastewater approval

This page covers wastewater approvals generally in Queensland. If you wish to know more information regarding your specific state or territory outside of Queensland, go to your local government website and they should be able to assist. Alternatively, speak to your local wastewater professional.

What legislation applies to wastewater approval in Queensland?

The Queensland Plumbing and Wastewater Code, the Plumbing and Drainage Act 2002 and AS1546.3:2017 are some of the main regulations and legislation that apply to the approval process.

Who is involved in the approval process?

There are two parties who are involved in the approval process: the local government in your area and the chief executive officer.

What approvals are needed?

Approvals must be obtained from your local government, in accordance with the Plumbing and Drainage Act 2018 and from the chief executive officer before you may install any wastewater application on your property.

Local government

If you wish to install a septic system of an on-site sewage treatment plant on your property, you must obtain local government approval. Remember, if you do not have the correct approvals you can not install anything, so take a look at the Queensland Government Local Government Directory if you need some help as to who you need to contact.

Please note that the exact approval process will change slightly depending on your local government, so ensure your research is specific to your area.

Plumbing and Drainage Act 2018

Additionally, you must obtain treatment plant approval in accordance with the Plumbing and Drainage Act 2018. This includes:

New treatment plants seeking treatment plant approval must obtain accreditation against AS1546.3:2017 or AS1546.4:2016.
A new application relating to a greywater treatment plant must comply with AS1546.4:2016 (Domestic greywater treatment systems) and the conformity assessment requirements.
A new application relating to a secondary on-site sewage treatment plant must comply with AS AS1546.3:2017 (Secondary Treatment Plants) and the conformity assessment requirements.

Chief executive officer

Lastly, you must obtain approval from the chief executive officer. To do this, you must submit Form 10 - Treatment plant approval. Go to the treatment plant approval Queensland Government site for more information. The following diagram sets out the chief executive officer process.

Why are approvals needed?

The approval process when it comes to wastewater systems is a very important one. It ensures that all proposed installations are compliant, safe and appropriately designed, as well as being suited to your household and its needs. Additionally, if there are problems with on-site wastewater facilities, this can result in negative effects on you, your neighbours and the environment, which is not ideal for anyone!
