Barwon Water has reached a significant milestone in upgrading Birregurra and its water supply by completing a 19-kilometre underground pipeline connecting the town to Colac’s water supply.
The remaining works, including the construction of a storage tank, are on track to be finished by August, marking a crucial step towards ensuring water quality, security, and sustainability for the community.
Barwon Water’s General Manager of Planning, Delivery, and Environment, Seamus Butcher, thanked the community for its patience while the exciting project was underway.
“Connecting the town to Colac’s water supply offers significant water savings and enhanced water quality for customers while reducing environmental impacts and costs,” Butcher said. “The upgrade will ensure high-quality and affordable water services for existing customers and accommodate future growth in the region.”
Butcher said the town’s treatment plant had reached the end of its operational life. Barwon Water analysis found the best approach to managing the town’s supply was connecting Birregurra to Colac’s supply.
“As this new water supply option is already treated at the Colac Water Treatment Plant, it alleviates the need to treat it at the old Birregurra plant, significantly reducing electricity usage, reducing carbon emissions and electricity costs. Many factors were considered, including our ability to ensure water quality, water security, environmental impacts, carbon emissions, cost, and bushfire resilience.”
Butcher said the supply upgrade would also save water by reducing losses from evaporation from the Birregurra storage basins, particularly during summer, and through other system efficiency improvements.
“The upgrade will ensure we can continue to provide high quality, affordable and secure services for our existing customers and cater for future growth.”
Construction of the pipeline, which will span from Forrest Street in Colac to Bowden Street in Birregurra, began in May 2023. The route follows road reserves and farmland, and above-ground infrastructure such as storage tanks and pressure-reducing valves will be installed along it.
At present, Birregurra’s water is sourced from the open Wurdee Boluc and Birregurra channels and stored in open basins before treatment.
As part of the upgrade, Birregurra customers will receive fluoridated water.
Fluoride is added to Colac’s water supply under the direction of the Victorian Government’s Department of Health.
The Colac water supply system, which can be connected to the Geelong system if needed, has the capacity to meet Birregurra’s demand, ensuring a seamless transition to the new water source.
The successful completion of the 19-kilometre pipeline represents a significant step forward in securing Birregurra’s water future, providing residents with reliable, high-quality water services for years to come.
It adds to the more than 6,850 kilometres of pipes that Barwon Water manages across the region.
Works on the remaining elements of the project are expected to be finished in August.
