The way to increase water availability in the future.

[go-tazz]

This is one way of increasing water availability in the future and if other states followed WA's example we would

have a more secure water supply as  Western Australia is the only state to run a full-scale groundwater

replenishment scheme.

Only problem I see with the fracking going on,it could destroy some of those aquifers and contaminate them.

I've always mentioned dams or pipes from up north in Qld to bring down water to go into dry rivers and

replenish those systems and town that rely on them and this would/could help stop towns running out of

water as another option.

Lake Eyre is a salt lake so why pump the water there?

You would then need a desalination plant for it to be of any use.

The new scheme will put the water into the Warrego.

@roge - we've got plenty of big rivers in the north of this country.

Or use solar power to crack sea water into fresh, and ship it far less distance to where it's needed. You're talking several thousand kilometres to get it from a foreign country.

"The theory behind the original Bradfield Scheme was that increasing irrigation and sustaining bodies of water in central Australia would ameliorate the climate, leading to increased rainfall, an expansion of fertile farmlands, greater agricultural production and food exports, and the creation of additional jobs.

That theory has largely been debunked over the following 80 plus years, but the new proposal does draw on some elements of the first plan — namely providing drought relief and driving agricultural production.

Instead of floodwaters being funnelled to Lake Eyre, the LNP's revised scheme would see the water travel into the Warrego River in south-west Queensland, which is a catchment within the Murray-Darling Basin."

The great artisian basin is absolutely huge, but there are individuals, irrigators and companies sucking water out of it at an astonishing rate in places. Around ten to fifteen years ago I attended a number of public meetings from concerned farmers who use the basin for stock water.

The government hydrologists who spoke at the meeting advised that the government was working on a mining policy which would see the basin drained of useful water in 200 years. What they didn't address was whether the reduced hydraulic pressure due to water mining would see an inflow of coastal and inland saline water into the aquifer and what the effects of large scale irrigation would have on salinity. They also didn't address the issue of water theft which was a well known problem amongst farmers even that far back.

400 kms from PNG coast to the first major river system in Australia - thought might be able to reverse flow southwards down various river systems but if not a dedicated channel system 

Narva Bay to Greifswald gas pipeline under the Baltic Sea is 1231 kms 

Victoria's north-south pipeline 70 kms 

Fresh water dumping into the sea from a large river on southern coast of PNG = 6 mega litres per second 

Be nice to capture some of that

We could tow the D-28 iceberg to Australia.

It would be a nice output but not as this stage but it could be the way it might have to go if the fracking poisons

the underground water aquifers and there is no safe water here in Aus.

The government seems to stuff everything else up that they get involved in so the destruction of the water

availability is certainly something else they could stuff up and their record in regards to water supply so far

certainly isn't the best.

I know the project would be mind-boggling , would have to be a viaduct for most of the way and a pipeline under the shipping channel , maybe more plausiable redirecting flows of some of the coastal Queensland rivers back inland via tunnels bored through the mountains - as for fracking and the potential perils , and what our Govt is doing to ensure safety , would be an interesing post subject

The Victoria River discharges, on average, 158 cubic metres per second. That's 1.58 megalitres. Less in the dry, more in the wet. As your PNG river would. And a helluva lot closer to Australia. And no having to negotiate with other governments.
