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.

Building on the preliminary business case completed by Building Queensland in 2017, the detailed business case is investigating the construction of Nullinga Dam and improvements to the existing water supply scheme. This more detailed assessment is analysing the project’s economic and financial viability, taking into consideration social and environmental impacts.

Request for information

To inform the demand profiles underpinning the detailed business case, a request for information has commenced. Building Queensland and SunWater are seeking information from interested parties about their potential water requirements from the proposed dam to support business and agricultural opportunities in the Mareeba Dimbulah Irrigation Area. Information about the nature of potential demand, including preference for priority and reliability as well as indicative prices, form part of the request.

The request for information closes 3 August 2018.

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