Call for water supply interest in Nullinga Dam

17 July 2018

A detailed business case for the proposed Nullinga Dam is underway with Building Queensland leading its development in partnership with the project proponent—SunWater. The proposed dam is in far north Queensland on the Walsh River within Mareeba Shire Council, approximately 55 kilometres south-west of Cairns and 24 kilometres south-west of Mareeba.

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 is an important step in the development of the detailed business case. Estimates of the yield of the proposed Nullinga Dam have been undertaken and recent studies have identified options for between 55,000 and 88,000 megalitres of medium priority allocations.

The detailed business case is investigating the construction of Nullinga Dam as well as improvements to the existing water supply scheme. It will determine the feasibility of the proposed future water infrastructure project. Based on the preliminary business case analysis undertaken by Building Queensland in 2017, this project has been identified in Building Queensland’s Infrastructure Pipeline Report as a priority for the state.

The request for information closes 3 August 2018. If you are interested in participating in this confidential request, visit the Marsden Jacob website.
