The Harmony Water Reservoir is the newest piece of major water infrastructure on the Sunshine Coast, standing at 10 metres high and 40 metres across.
Unitywater CEO, Anna Jackson, said it would support about 7,800 new homes.
“We provide essential, safe, reliable and sustainable water and wastewater services, and this asset is part of our broader Aura and Harmony capital delivery program to cater for these growing communities,” Ms Jackson said.
“An interesting design feature of this project is its construction, which comprises 40 concrete panels – all of them poured on site – that were raised up and pulled together with steel cables, the same technique used to make a wine barrel,” she said.
“It’s a significant piece of infrastructure, delivered in collaboration with our construction partner McConnell Dowell, that is now supplying water to homes in Harmony through a 2.6-kilometre pipeline from the reservoir.”
Sunshine Coast Mayor, Rosanna Natoli, attended the milestone event and said it highlighted the important investment in essential services for the growing Sunshine Coast.
“Harmony is one of our region’s key master-planned communities and this will be of enormous benefit to those who call it home,” Ms Natoli said.
“Delivering the right infrastructure to support much-needed housing for the Sunshine Coast is so important as our population grows,’’ she said.
The Harmony Water project is part of Unitywater’s broader Aura and Harmony Program which when completed, will have delivered 27.6 kilometres of water and wastewater pipelines, two large water reservoirs, and a new wastewater pump station, to provide essential services for more than 71,000 future residents of Aura and Harmony.
The program won the 2025 UDIA Queensland Excellence Award for Community Engagement.
