The proposed Nullinga Dam site is located on the Walsh River in the Atherton Tablelands and has been proposed as a future water supply to serve growing urban demand in Cairns and to stimulate irrigated agriculture in the region, by supplementing existing supplies.
The potential for population increase stemming from the development of the proposed Aquis Resort is a driver of high-series water demand projections in Cairns.
The Business Case will be delivered by Building Queensland in two stages. The first stage will involve the development of a Preliminary Business Case.
The Preliminary Business Case will investigate the potential for Nullinga Dam and other options to address the identified future water supply shortfall in the region. The scope of work will include water demand assessments, preliminary analysis of costs, risks and benefits, consultation with key stakeholders and recommendations for the future of the project.
The Preliminary Business Case is anticipated to be delivered to government for consideration in the first half of 2017. Subject to the outcomes of the Preliminary Business Case and government approval to proceed, the second stage will involve Building Queensland undertaking a full Business Case.
The Preliminary Business Case is being led by Building Queensland in partnership with the Department of Energy and Water Supply and SunWater. It is funded from the Australian Government National Water Infrastructure Development Fund.
