Aura and Harmony Program

Unitywater’s program of works will provide essential water and wastewater services for the growing Aura and Harmony communities on the Sunshine Coast.

With a projected population of 50,000 residents in Aura by 2050 and 21,000 residents in Harmony by 2036, this program is vital in meeting the future demands of the communities, ensuring their long-term sustainability and development.

The program includes three major projects:

Unitywater is committed to delivering sustainable and reliable infrastructure that will improve the network's overall reliability, meet water and wastewater demand for its customers, and deliver significant benefits to the growing region.

The construction contract was awarded to McConnell Dowell in March 2023. Construction activities are well underway and progressing well. The program is anticipated to be complete by late 2026, weather and construction conditions permitting.

    How many trucks of concrete does it take to pour the base of a 12 megalitre water reservoir?

    To paint a picture, one megalitre is the size of an Olympic-sized swimming pool and recently it took 38 trucks six hours to deliver 280 cubic meters of concrete for the foundation of the new Tanawha Reservoir.

    Project details:

    • The Harmony Water Project includes construction of a new water reservoir at Tanawha and installation of 2.6kms of new water pipeline from the reservoir to Harmony in Palmview.
    • Construction commenced in mid 2023 and is expected to be completed by late 2026, weather and construction conditions permitting.
    • Together with our construction partner McConnell Dowell, we are working closely with the local community to keep them informed about the project and reduce any disruption.
