Nullinga Dam and Mareeba Dimbulah Water Supply Scheme Improvements

Building Queensland is leading the development of the Nullinga Dam and Mareeba Dimbulah Water Supply Scheme Improvements Detailed Business Case in partnership with SunWater. The proposed Nullinga Dam site is located on the Walsh River in the Atherton Tablelands. It has been proposed as a future water supply to serve growing urban demand in Cairns and to stimulate irrigated agriculture in the region.

Extending on the preliminary analysis completed in 2017, the detailed business case has so far investigated possible reforms to the Mareeba Dimbulah Water Supply Scheme (MDWSS), additional channel upgrades and the potential Nullinga Dam. Some MDWSS channel upgrades are already funded by the Australian Government’s National Water Infrastructure Development Fund.

Building Queensland expects to complete the detailed business case in Q2 2019 before presenting it to the Queensland Government for consideration.
