MidCoast Water awards Nabiac Water Treatment Plant tender

The provision of an additional water supply system to support MidCoast Water’s largest water scheme has reached another milestone with the awarding of a $9.8 million tender to construct a water treatment plant at Nabiac awarded to Stirloch Pty Ltd.

The construction of the Nabiac Water Treatment Plant is part of the $34.6 million Nabiac Inland Dune Aquifer Water Supply System project, which will ultimately deliver a second water source to the region and support the Manning scheme.

The Manning scheme supplies 36,000 customers in the area from Crowdy Head in the north to Tarbuck Bay in the south.

In making the decision to award the contract, MidCoast Water chairperson John Turner said that Stirloch Constructions Pty Ltd was one of four shortlisted tenderers for the water treatment plant construction. Stirloch were ultimately successful in obtaining the contract after an extensive process to ensure best value and demonstrated capability to deliver the desired outcome.

“The other pleasing news is that the tender assessment process resulted in a reduction in the planned budget for the project in the order of $800,000,” Mr Turner said.

The connection of a second water source for this large area will provide security of supply in the event of extended dry weather and backup in the event of equipment malfunction.

“When operational the Nabiac system will allow us to reduce the volume of water we extract from the Manning River during times of low flow, this both improves water security and environmental outcomes for our communities,” MidCoast Water’s general manager Ken Gouldthorp explained.

The project has three main components, the establishment of an extensive bore network, a water treatment plant approximately five kilometres south-east of the Nabiac township and a pumping station at Darawank, next to the Lakes Way. Both the bore network and pumping station elements of the project have been completed.
