Improvements on key Brisbane water supply asset now complete

Significant refurbishment work has been carried out on one of Brisbane’s largest water supply assets to boost water security across the region.

Sparkes Hill Reservoir

A number of improvements were made to the Sparkes Hill Reservoir, which holds up to 16 per cent of Brisbane’s water supply.

Seqwater Chief Executive Officer Neil Brennan, said the need for improvements at Sparkes Hill were identified following an engineering assessment in 2018. 

“The Sparkes Hill Reservoir holds up to 94 megalitres of water and is an important part of the SEQ Water Grid,” Mr Brennan said.

“The reservoir was originally constructed in the 1970s and just like our dams and treatment plants these are long-life assets and require continual monitoring and maintenance.”

Mr Brennan said the delivery of the refurbishment work had created up to 75 jobs and that completion of the project had improved the long-term reliability of the reservoir and network.

Work included improving the stability of the reservoir roof, designing and installing internal roof support brackets, strengthening internal columns, and sealing the entire roof structure with a liquid membrane to better protect the stored drinking water.

During the upgrade, the smaller reservoir on site was ramped up to provide the alternative supply.
