Wastewater treatment
The Development Application (DA) has been approved for the bioreactor (secondary treatment) upgrades.
On 12 May 2025, we submitted an amendment to the approved bioreactor development approval (DA#202341913) to the Environment, Planning and Sustainable Development Directorate (EPSDD).
The application is currently open for public notification from 29 May until 20 June 2025. This gives stakeholders and members of the community another opportunity to provide submissions and participate in these projects.

The timing of the DA for the biosolids treatment renewal project is yet to be confirmed.
Our wastewater treatment process
Our wastewater treatment process
Our wastewater treatment plant has served Canberra’s needs for decades, but some of our assets are ageing and elements of the treatment process are nearing capacity. We have a responsibility to protect our environment and continue providing high-quality wastewater services to our community. To do this we need to upgrade, or replace, elements of our treatment process.
Our plans include two significant projects for our primary wastewater treatment plant, Lower Molonglo Water Quality Control Centre (LMWQCC). The first project is focused on our bioreactors and the other targets biosolids.
After rigorous assessment of a number of options, we have now selected technologies for each project. To find out more about the options considered and our decision making process visit our project page.
Timeline – phase one engagement
The purpose of phase one of our engagement was to inform further communication and engagement on the projects and to test our thinking and decision-making approach.
Timeline – phase two engagement
The purpose of phase two of our engagement is educate the broader community about the projects, test ideas and seek feedback.
