Could Australian cities run out of WATER? Fears Cape Town-style drought could soon hit the country

Could Australia run out of water like Capetown in South Africa? One scientist has raised fears

Scientist Dr Ian Wright has concerns about the dwindling water supplies in Perth

Adelaide is the next most water stressed capital in Australia, the scientist said

Sydney, Melbourne and Brisbane have major dams with big storage capacity

Cape town has much less storage capacity and is close to ground zero

A scientist has questioned whether Australia’s water-stressed capitals including Adelaide and Perth could suffer a Cape Town like disaster. 

The South African city, double the size of Perth, is currently a natural disaster area and desperately fighting ‘Ground Zero’ day. 

Perth has suffered increasing water stress for nearly 50 years, with inflows shrinking by 90 per cent since 1974, according to a Western Sydney University scientist.

Dr Ian Wright believes the ‘situation in Capetown’ is similar to Perth, which he says has suffered a reduction in inflows by nearly 90 per cent since 1974. 

‘For it’s two million people the inflows equated to only 15.6 litres per person per day, yet in 2015/6 Perth residents consumed an average of nearly 350 litres per day, he wrote in The Conversation. 

He discussed the city’s reliance on desalination and groundwater which is considered controversial and expensive.

‘Perth is the only Australian capital to rely so heavily on desalination and groundwater for its water supply,’ he wrote. 

He said Australia’s next ‘most water-stressed’ capital is Adelaide and east coast cities have also experienced water stress. 

But it is not all doom and gloom.

Brisbane, Melbourne and Sydney have built large dams with massive storage capacity for residents, Dr Wright reassured readers in his article.

He said Brisbane’s storage capacity works out at one million litres per resident when storages are full, compared to just 225,000 litres per resident in Capetown.   

‘Capetown is constructing a number of small desalination plants while anxiously waiting for the onset of the region’s formerly regular winter rains,’ he said.

This trend is worrisome.

Water stress, thinking of 3/4 of the Earth’s surface covered by water.
