“Demand management” won’t solve Sydney’s water crisis

Sydney’s water storages continue to plunge at an alarming rate that makes the Millennium Drought look like child’s play:

This has prompted the Berejiklian Government to fast-track an expansion of Sydney’s desalination plant, doubling its size in order to provide more than 30% of Sydney’s drinking water:

NSW Water Minister Melinda Pavey… said the expansion of the plant in Kurnell, in Sydney’s south, was a “key element in protecting Sydney’s water security”.

“The expansion of the plant should be undertaken as quickly as practicable and in a prudent and efficient manner to deliver at least an additional 250 megalitres of drinking water per day averaged over a 12-month period,” Ms Pavey said…

“We have never seen dam levels drop this fast in Sydney, so we need to move as fast to shore up our supply.”

At the same time, the Berejiklian Government is also fast tracking housing developments to cater for an additional two million people in Sydney over the next two decades, and will also resort to so-called “demand management” to curb water use:

The NSW Government is to fast-track housing developments for a Sydney population increase of nearly two million people despite a lack of new water sources.

Sustainable Australia Party spokesman Kelvin Thomson said development planners had failed to take into account the water shortage.

‘That level of population growth for Sydney is not sustainable,’ he told Daily Mail Australia on Saturday.

‘State and Federal governments need to look at the role of migration as the driver of population growth.’

The population of Greater Sydney is forecast to rise to 7.1 million people over the next 21 years, according to NSW Government population projection figures updated earlier this month, with more than half of the growth coming from migration…

The extra 1.9 million people projected would create additional demand of 347.7 million litres of water per day.

Each year they would need 126.9 gigalitres of fresh water, which is more than one fifth the size of Sydney Harbour – which holds 500 gigalitres of water…

The Metropolitan Water Plan also talks about cutting people’s water usage through ‘demand management’.

Sydney’s evaporating water supplies are obviously being exacerbated by the federal Government’s ‘Big Australia’ mass immigration policy.

Since the Millennial Drought ended in 2006, Sydney’s population has ballooned by one million people (~20%), which has massively increased water demand.

The maths is simple. With average water use of 183 litres per day according to Sydney Water, the additional 1,000,000 people represents an extra 183 million litres of extra water consumed every day.

Given Sydney’s population is projected by the ABS to swell by around 4.5 million people over the next 48 years – almost doubling the city’s population – driven completely by mass immigration:

And with droughts to become more common and severe and evapotranspiration rates to skyrocket.

The New South Wales Government will need to build a battery of expensive, energy-sucking and environmentally damaging desalination plants along the coast, which will dramatically increase users’ water and energy costs.

These are just some of the many hidden costs of the bipartisan mass immigration ‘Big Australia’ policy that has been undemocratically foisted on the Australian people.
