Cedar Grove Wastewater (Sewage) Treatment Plant

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 concept 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 will open for a period of 20 business days. This will commence 19 February 2018 to 16 March 2018.

In order to make a valid and considered submission you must:

Lodge your submission between the dates of 19 February 2018 to 16 March 2018. You can do this by emailing your submission to: pdadevelopmentassessment@dilgp.qld.gov.au or alternatively, mailing to: EDQDevelopment Assessment team, Department of Infrastructure, Local Government and Planning, GPO Box 2202, Brisbane 4001.

Your submission must include your name, the application reference number (DEV2017/826), and the name of the PDA (Greater Flagstone).

A hard copy of the DA application can be viewed at any Logan City Council Customer Service Centre – Jimboomba, Beenleigh or Logan Central.

Drinking water supply changes in Logan South

Logan City Council is committed to a high-quality, secure water supply for all Logan residents and water customers. From mid-October, Council will be upgrading the water supply to the Logan South Water Supply Zone. This upgrade includes the installation of a disinfection facility which will operate during summer months to provide the best possible health protection to residents. The new facility will run when necessary for the protection of public health.

The works will impact the following suburbs:

  • Cedar Grove
  • Cedar Vale
  • Chambers Flat
  • Flagstone
  • Greenbank
  • Jimboomba
  • Logan Village
  • Mundoolun
  • Munruben
  • New Beith
  • North Maclean
  • Park Ridge South
  • South Maclean
  • Stockleigh
  • Woodhill
  • Yarrabilba

The new facility is necessary to ensure the water network is kept clean and the water supplied continues to meet the stringent requirements of the Australian Drinking Water Guidelines. We acknowledge that chlorine levels in the water may be noticeable to some residents. During the initial operation of this facility, it is possible there may be some initial temporary incidents of discoloured water.  We believe however that residents will understand that the highest standard water supply system possible is essential for community health. You can be assured water supplied by Council will continue to meet all health regulations.

During Works:

  • Some water mains will be flushed, however there should be no need to temporarily interrupt water supply. If any residents and businesses are affected by planned interruptions, they will be provided with written notification at least 48 hours in advance.
  • Some residents may notice a change in the taste, odour or appearance of their water. Temporary discolouration of the water supply can be managed in most cases by running a tap at your property for a couple of minutes. If discolouration persists please contact Council and we will flush the affected water mains if necessary.
  • There are some actions you can take to minimise the odour of chlorine in drinking water.  It is often sufficient to leave tap water in an open jug in the fridge overnight to significantly reduce its odour.  If you choose to filter the water, the filter must contain activated carbon/charcoal to be effective for the reduction of chlorine.
  • The altered chlorine concentration may impact non-drinking uses of water such as fish keeping. We recommend you obtain specialist advice regarding the effects of chlorinated water in such cases.

Council has developed a fact sheet which includes a list of frequently asked questions.

For information regarding rainwater tanks, please refer to the Using your rainwater tank  (PDF 192 KB) fact sheet.

During this time, if you experience persistent discoloured water please contact Council’s customer service team on 3412 3412.

Inflow & infiltration inspection program

The Logan wastewater system experiences large volumes of overflows during severe wet weather events. These types of events have a significant impact on the wastewater network, overwhelming its capacity and resulting in wastewater overflows into the environment.

Stormwater entering the wastewater network as a result of defective, improper and illegal stormwater connections, principally from residential connections, is a major cause of wastewater overflows. By identifying sources and lessening the risk of stormwater entering the wastewater system, Logan City Council is committed to significantly reducing the number of wastewater overflows that occur during wet weather.

With this goal in mind, Council undertakes systematic inspection programs to identify defective, improper and illegal stormwater connections to the wastewater system, in accordance with the provisions of sections 133 and 134 of the Local Government Act 2009. Details of the inspection programs are included below.

For further information please contact Council's Logan Water Infrastructure Alliance on (07) 3412 9600.

Shailer Park

An inspection program in Shailer Park will commence on 1 March 2018. Voluntary Compliance letters will then be sent to property owners where defects have been identified. Council will be liaising with property owners and providing assistance/advice where possible to ensure that these defects are rectified.

Mount Warren Park

An inspection program in Mount Warren Park will commence in mid-March 2018. Voluntary Compliance letters will then be sent to property owners where defects have been identified. Council will be liaising with property owners and providing assistance/advice where possible to ensure that these defects are rectified.

Council appreciates property owners' participation in the inspection program, and the support shown for reducing wastewater overflows into our environment.
