The utility was recognised for the reconfiguration of the Coolum, Suncoast and Maroochydore sewage treatment infrastructure.
The project was completed in 2014 and resulted in the closure of the Suncoast plant, a move which is estimated to save Unitywater $A57 million over the lifetime of the plant.
Simon Taylor, Unitywater Executive Manager of Planning & Capital Development, said the project was a good example of the innovative thinking practiced at Unitywater.
“Traditional thinking would have seen us simply create bigger versions of the existing treatment plants. However our engineers thought outside the square and delivered a solution that actually closed down a plant, drilled a pipeline under the Maroochy River and built a wetland at the Coolum plant to help treat sewage,” said Mr Taylor.
In 2014 Unitywater received an honourable mention at the Australian Water Association awards for work on the Maleny Sewage Treatment Plant and Wetland project.
