ACCIONA and BMD have been selected by TasWater as the preferred bidder for the design and construction to the existing Blacksman Bay Sewage Treatment Plant which is valued at A$39M.
The existing sewage treatment plant has been operating for 30 years and is at its end of its service life. An upgrade will be needed in order to accommodate the future growth in Kingborough. This upgrade will increase capacity from 4.1 Million Litres per Day to 8.5 Million Litres per Day.
The upgrade to the sewage plant will include construction to earth works, new roadways, new buildings and new tanks as well as equipment installation and commissioning. An Environmental Management Plan will be required before construction in order to evaluate site management, erosion control, air quality, flora and fauna, noise management, and traffic management.
Location: Kingborough, Tasmania
Our role: Introducing a wastewater treatment process called Intermittently Decanted Extended Aeration (IDEA) which is combined with Sequential Batch Reactor (SBR) technology in order to provide a cost efficient way of treating wastewater.
Infrastructure: Kingborough Sewerage System
Project Value: A$39M
Estimated completion date: 21 months to design and construct
Maintenance Period: 24 months of performance evaluation
ACCIONA and BMD will be the delivery contractors for the project with design and construction to the upgrade of the existing Blackmans Bay Sewage Treatment Plant.
Current treatment capacity 4.1 Million Litres per Day
Increase of treatment capacity to 8.5 Million Litres per Day
Construction of a new sewage pipeline to take waste from Margate, Electrona and Howden to the Blackmans Bay Sewage Treatment Plant
21 months to design and construct
The Kingborough Sewerage Upgrade Project will introduce a wastewater treatment process called Intermittently Decanted Extended Aeration (IDEA) which will be combined with Sequential Batch Reactor (SBR) technology in order to provide a cost efficient way of treating wastewater
Closure of 3 existing and underperforming sewage plants at Electrona, Margate, and North West Bay Golf Club
One of the sustainable components of this project will be to treat the wastewater without any chemical dosing, utilising Ultra Violet disinfection instead of chlorine this will help to promote a safe environment for the plant operators and reducing any impacts on the environment
This upgrade will improve the existing odour issues at Blackmans Bay and Dru Point (Margate)
The construction of the new pipeline known as the Blue pipeline route were considered on community views, environmental consideration, engineering considerations, and lastly on cost and operational efficiency
ACCIONA and BMD have been selected to lead the design and construction of the Kingborough Sewerage Upgrade Project. Design and construction will take 21 months, and a 24 month performance evaluation period. The project is currently underway.
