Australia is on track for a significant expansion of desalination capacity \u2014 converting seawater to freshwater \u2014 to meet the needs of a swelling population at a time of declining average rainfall.<\/p>\n
The world\u2019s driest inhabited continent is projected to build or expand 11 desalination plants worth more than A$23 billion ($15 billion) over the next 10 years, according to a research report by Dominic McNally at Oxford Economics.<\/p>\n

\u201cOur population growth forecasts imply an additional 190GL\/year in household water demand across major cities by 2035, while the booming data center industry also threatens to rapidly expand urban water use,\u201d he said.<\/p>\n
\u201cThis growing demand coincides with falling average rainfall in major population centers, increasing the vulnerability of existing infrastructure.\u201d<\/p>\n

\nWater construction activity slowed after 2010 as a severe drought receded. However, recent dry periods have reignited interest in water security and coincide with a new boom in water infrastructure investment, including desalination, McNally said.<\/p>\n<\/blockquote>\n
Households regularly face summer water restrictions at times of drought, particularly in the southern state of South Australia, which is mainly classified as arid or semi-arid. Oxford reckons that over the next 10 years, demand for drinkable water will increase by more than 10% in some areas.<\/p>\n
Meanwhile, BHP Group plans to spend\u00a0A$840 million to bolster its Olympic Dam underground copper project in South Australia.<\/p>\n

Oxford says this, together with other nearby resource projects, will require a desalination plant to service increased mining and refining activity, by pumping water from the Spencer Gulf.<\/p>\n
\nGreen hydrogen and ammonia production also require significant energy and fresh water, favoring production in arid regions like the Pilbara in Western Australia and Gladstone in Queensland, Oxford said.<\/p>\n<\/blockquote>\n
Industrial uses will drive particularly strong construction pipelines in WA, SA, and QLD in the late 2020s, it added.<\/p>\n
\u201cThis has renewed interest among water authorities, proposing expanding desalination capacity as part of their asset investment plans over the coming decade,\u201d McNally said.<\/p>\n
