Keep informed about the Mount Barker Wastewater Facility upgrades, the Mount Barker Wastewater Facility Environmental Improvement Program, recycled water discharges to the Mount Barker Creek and much more.

The Mount Barker District Council currently operates the largest South Australian Council Community Wastewater Management Scheme utilising proven management processes and procedures. It is a licensed Water Industry Entity and considers itself well positioned to provide wastewater solutions to the future growth areas.

The existing Mount Barker Wastewater Treatment Plant services wastewater catchments within the Mount Barker, Littlehampton, Nairne and Brukunga townships.

In December 2010 the State Government rezoned a large amount of land within the Council area (particularly in Mount Barker and Nairne townships) to accommodate state population growth. This Ministerial Development Plan Amendment (MDPA) resulted in the rezoning of approximately 1,300 Ha as residential development and many developers in the MDPA area have signed agreements with Council (approximately 3000 lots) to provide wastewater services.

The major township of Mount Barker has been growing at a consistent rate of 2.5% p.a. for the past decade and is forecast to grow by 64% over a 20-year period based on population data obtained from the 2016 census of 33,810 to 55,416 by 2036. This rezoning will almost certainly ensure that this trend continues in the foreseeable future. With this growth Mount Barker will become the second largest city in the State after Adelaide.

In response, Council is developing a strategy to upgrade and expand existing wastewater and recycled water infrastructure to service growth within the MDPA area and also to provide acceptable levels of service to existing customers during the growth period. The upgrade and expansion of infrastructure will reflect Council’s future strategies by considering public health outcomes and best practice wastewater management principles.

The Mount Barker Wastewater Treatment Plant currently treats an average dry weather flow (ADWF) of approximately 4.2 ML/day using aerated lagoon followed by pre-treatment storage lagoon and tertiary treatment processes. The treated effluent is either discharged to the Mount Barker Creek via Laratinga wetlands or diverts for further treatment to produce South Australian standard Class A reclaimed water for reuse. Council's strategic objective is to achieve 100% reuse of recycled water and is working diligently to achieve this outcome.

  • Council builds on its reputation as a leader in wastewater management

    Share on Facebook Share on Twitter Share on Linkedin Email this link
    05 August, 2020

    Mount Barker District Council is working hard to improve its environmental performance with respect to the treatment of wastewater. A condition of Council’s wastewater licence with the Environment Protection Authority (EPA) is the development of an approved Environmental Improvement Program (EIP).

    A draft EIP went out to community consultation in May and the final program was endorsed by Council at its June meeting.

    Last month, Council’s EIP was officially approved by the Environment Protection Authority.

    Mayor Ann Ferguson says, “Council’s Wastewater Environmental Improvement Program demonstrates leadership in the protection and enhancement of the local environment.”

    The overarching requirement of the EIP is for council to minimise the discharge of treated wastewater to Mount Barker Creek and maximise the use of recycled water coming from the Wastewater Treatment Plant.

    The EIP will result in improvements to the Mount Barker Creek and the Laratinga Wetlands over the longer term and this in turn will benefit those people in the community that live or recreate along the creek.

    “As we deal with issues around climate change and population growth, we need to make sure our wastewater management is able to meet these challenges now and for future generations.” Mayor Ferguson added.

    The approved Mount Barker Wastewater Environmental Improvement Program can be viewed from Council’s Your Say website https://yoursay.mountbarker.sa.gov.au/mount-barker-wastewater-facility
