Kingborough Sewerage Upgrade Project

Update April 2017

The Development Application for the upgrade to the Blackmans Bay Sewage Treatment Plant has been approved by Kingborough Council and the Environment Protection Authority. Construction work will start on this project in the coming weeks.

This work is part of the broader Kingborough Sewerage Upgrade Project, designed to improve environmental outcomes and meet the needs of the fast-developing Kingborough area. This project will see the under-performing Electrona, Margate and Howden sewage treatment plants closed down, and their flows diverted to Blackmans Bay for more effective treatment.

The current Blackmans Bay Sewage Treatment Plant has been operating for more than 30 years and while it has done a good job, it is nearing the end of its serviceable life. The upgraded Blackmans Bay plant will offer a significant improvement in odour and noise in comparison to the existing plant, and increase capacity to treat a higher volume of sewage to a better quality with more reliability – accommodating future growth in Kingborough.

More information on construction will be provided here as it becomes available. For now, if you are after more information on the Blackmans Bay Sewage Treatment Plant upgrade, read our most recent newsletter here.

The contractor

The tender for this project has been awarded to a joint venture between BMD Constructions and ACCIONA Agua, collectively referred to as the BAJV.

  • BMD Constructions is part of the BMD Group, a well-established Australian provider of engineering design, construction and development. They have experience in multiple projects in water and wastewater, including upgrades and expansions of sewage treatment plants at Ludmilla in the Northern Territory, and Christies Beach in South Australia.
  • ACCIONA Agua is one of the most respected international contractors in the water industry, providing water solutions to more than 50 million people in 20 countries. Among their projects is the construction and operation of the world’s largest sewage treatment plant in Atotonilco, Mexico.

As TasWater's contractor, BAJV is required to develop an Environmental Management Plan prior to construction to account for site management, erosion control, air quality, flora and fauna, noise management, traffic management and other issues.

About the Kingborough Sewerage Upgrade Project

The Kingborough Sewerage Upgrade Project includes three key components:

  • Upgrading the Blackmans Bay Sewage Treatment Plant
  • Constructing a new sewage pipeline to take waste from Margate, Electrona and Howden to the Blackmans Bay plant
  • Closing three existing, under performing (non-compliant) sewage treatment plants at Electrona, Margate (Dru Point) and in the North West Bay Golf Club, and pumping sewage from those areas to the new Blackmans Bay plant

Project benefits

The Kingborough Sewerage Upgrade Project will:

  • Consolidate and optimise the Kingborough area sewerage system and includes closing three under-performing sewage treatment plants at Electrona, Margate and Howden
  • Address historic odour issues at Blackmans Bay and Dru Point (Margate) treatment plants, and allow for future growth in the Kingborough region as well as ensuring assets deliver reliable service for future generations
  • Deliver significant environmental benefits, such as releasing better quality effluent into the Derwent Estuary and preventing effluent flowing into North West Bay
  • Enable TasWater to meet Environment Protection Authority compliance.

This long-term sewerage strategy for Kingborough follows a recommendation from Kingborough Council in 2009. TasWater has been engaging with the Kingborough community since 2013 (while it was still Southern Water) on the Kingborough Sewerage Project.

The new sewage pipeline

The proposed pipeline from Electrona, Margate and Howden is currently going through its own separate approvals process and TasWater is in discussions with Kingborough Council, Parks & Wildlife and the Federal Department of Environment and Energy regarding various aspects of this project, including the proposal to run part of the pipeline through the Scarborough Fire Trail in the Peter Murrell Reserve.

TasWater believes the selected route presents a low risk in terms of both construction and operation. It has been selected based on an analysis of multiple criteria, including environmental and engineering factors such as geology, topography of land, the power needed to pump waste through the pipe, the length of the pipe, the amount of pressure in the pipe and reducing sewage detention times to prevent odour.

This route passes through the Peter Murrell Conservation Area (not the State Reserve within it), running underground along the reserve’s perimeter and the Scarborough Fire Trail. The pipeline will follow an existing water main through the Scarborough Fire Trail, which also already contains an existing sewer main and above ground power lines. The proposed pipeline also runs beneath the Lady Penryhn Fire Trail from the west end of Lady Penryn Drive through to Burwood Drive, in an existing infrastructure corridor adjacent to an existing sewage pump station.

You can see the route selected here (during community consultation this was previously referred to as the 'blue route').

By selecting this route, TasWater is able to save at least $2 million in both construction and whole-of-life costs to the project. Savings of this kind are needed so TasWater can continue to invest in much-needed upgrades to drinking water and sewerage systems throughout the state.

If this route is approved, TasWater will work within the limitations established in our environmental management plan and any approval conditions. Through careful planning, management and implementation, vegetation removal will be minimal and we do not anticipate any loss of endangered species or residential amenity.

Construction will be finished in the second half of 2018.

TasWater consultation

TasWater’s community engagement is designed to both inform the community about the project and provide an opportunity for the community to discuss details and provide feedback.

On this project, TasWater has worked with the community to ensure that concerns and aspirations are directly reflected in the alternatives developed and to provide feedback on how community input influenced the decision.

TasWater understands the importance of engaging with our communities and will continue to communicate with residents as we strive to deliver optimal outcomes for the entire community.
