Why is the Kingborough Sewerage Upgrade happening?

The upgrade of the sewerage system is being undertaken for various reasons including:

  • The project will benefit the Kingborough area, both now and for future generations, by consolidating and enhancing the Kingborough sewerage system
  • An upgraded Blackmans Bay Sewage Treatment Plant will centralise waste from local catchments and treat it to a higher standard before it is discharged into the Derwent Estuary and ensure it complies with environmental regulations
  • The proposed upgrade will provide enhanced odour management at the existing Blackmans Bay STP
  • The proposed upgrade will see underperforming sewage treatment plants at Electrona, Margate and Howden closed
  • The proposed upgrade will service future growth and provide sufficient capacity for continuing development within the region
  • A consolidated system reduces ongoing costs by reducing several treatment plants to one site.

What are the benefits of the Kingborough Sewerage Upgrade?

The proposed upgrade will benefit the Kingborough area in a variety of ways including:

  • Providing greater capacity and enhanced odour management.
  • Reducing ongoing costs by consolidating several regional monitoring systems to one site.
  • Providing sufficient capacity for future growth and continuing development within the region.
  • Improving effluent quality and ensure discharge into the Derwent Estuary complies with environmental regulations.

Why is the Blackmans Bay Sewage Treatment Plant being upgraded?

The Blackmans Bay Sewage Treatment Plant has been operating for 30 years and is nearing the end of its service life. Additionally, residents have reported noise and odour issues and the effluent discharged to the River Derwent has not always fully complied with EPA requirements. 

An upgraded Blackmans Bay STP will improve effluent quality and ensure the discharge into the Derwent Estuary complies with environmental regulations. 

Increasing capacity at the Blackmans Bay STP will cater for population growth and future demand. 

Has TasWater done a full environmental assessment for the Blackmans Bay Sewage Treatment Plant?

TasWater's Development Application has been approved by Kingborough Council and the Environment Protection Agency. This included a Development Plan & Environmental Management Plan. These documents were assessed under the Environmental Management and Pollution Control Act 1994 (EMPCA). 

How was the pipe route chosen?

The Blue pipeline route decision was based on a range of important criteria such as community views, environmental considerations, engineering considerations, cost and operational efficiency over the life of the system. 

Can I connect to the proposed sewerage pipeline, once complete?

The Kingborough Sewerage Upgrade project is a proposed upgrade to the existing sewerage system. There are no plans to connect new customers and new developments to the sewerage pipeline as part of this project. However, this project would provide capacity for future connections once complete.

The proposed pipeline is a pressurised sewerage main, not a gravity main. This means it is not possible for properties to connect directly into it without appropriate infrastructure in place.

If approved, once the Kingborough Sewerage Upgrade Project is complete, a request for sewerage connection can be submitted to TasWater through the usual development application process. This can be done via calling TasWater on 13 6992 or email enquiries@taswater.com.au for connection enquiries.
