Cedar Grove Wastewater Treatment Plant – Stage 1

About this project

Council’s Logan Water Infrastructure Alliance is designing an advanced wastewater (sewage) treatment plant at Cedar Grove. This facility will provide essential services to the growing community in the Queensland Government’s Greater Flagstone Priority Development Area (PDA).

Under the Queensland Government’s ShapingSEQ South East Queensland Regional Plan 2017, Logan City’s south west region is identified as a major hub for residential, commercial and industrial development. This region includes the Greater Flagstone PDA.

As development progresses and the population increases in the PDA, additional critical infrastructure such as water and wastewater pipelines and treatment facilities will be required.

Current status

Design of Stage 1 of the Cedar Grove wastewater treatment plant is underway. Activities include conducting a range of technical studies and engaging with Queensland Government agencies, community members and other stakeholders about infrastructure concepts.

A draft master plan (PDF 1603 KB)for the wastewater treatment plant site has been prepared.

A public notification period for Council’s Material Change of Use application (DA Application number is DEV2017/826) for Stage 1 of the wastewater treatment plant is expected to commence in February 2018.
