Northern Water Supply - Business Case. Have Your Say!

Published 9th February 2023

Exploring a new secure and sustainable water supply for the future.

The Northern Water Supply (NWS) project is one of a number of projects being considered for the Upper Spencer Gulf as part of the State Government’s plan to decarbonise local industry, provide for future jobs and economic development, and position the region as a global leader in the net-zero economy.

As part of the NWS, the South Australian Government is assessing the potential for a new and sustainable water supply for the far north and Upper Spencer Gulf. The project aims to sustainably support regional communities and industries now and into the future.

This assessment takes the form of a business case which will evaluate the environmental, social and economic benefits and impacts of building a seawater desalination plant in the region, along with a 450km pipeline which will transport the desalinated water to communities and industries across the region, including the emerging Hydrogen industry.

We are currently looking at where might be most suitable to conduct in-depth studies on the feasibility of building a desalination plant and your views are a critical part of identifying issues/risks and opportunities/benefits that should be considered as part of the assessment process. This will in turn help inform the government’s decision on whether to further progress the Northern Water Supply project beyond the current phase.

Three sites have been identified as potentially feasible. These are shown below. For more information about the how a study site will be chosen see the study site selection fact sheet
