There is a danger that Adelaide could run out of water by the summer of 2008-09 after disappointing rains this winter failed to recharge the city's main supply from the Murray River. Little rain means little runoff. The possibility of the South Australian capital forced to rely on emergency supplies of water from January 2009 can be averted only by well-above-average rainfall next winter in the Murray-Darling Basin.
However, the chances of the city's estimated eight months of storage being replenished before next winter are fading because the likelihood of above-average rain over the next three months is low.

The implication is that we are now running the system on inflows without any dams. Where is the water going to come from in the future? How come Adelaide has not planned for alternative water supplies, including desalination, water recycling and stormwater harvesting?
The Rann Government has been hot on publicizing climate change but has done no planning for water apart from restricting demand for water in the form of a bucket-only watering policy. This is in such a contrast to Western Australia, which is approaching the water scarcity problem with a long-term solution in mind Perth has a desalination plant that has been operating since November and has the capacity to deliver 45GL/annum. By 2011 another plant there will deliver an additional 50GL/annum with possible upgrade to 100GL/annum. That 95GL is equivalent to about half what SA Water delivers to Adelaide each year.
Why not Adelaide? Why is a taskforce just looking at this? Where are the plans for storm water retention and recycling? Why isn't the Rann Government being pro-active to take advantage of the opportunity to become a world leader in water management and then export our expertise and solutions across the world?
Update:6 September
Darryl Gobbett, an economist writing an op-ed in The Advertiser says:
Adelaide needs to turn off its Murray tap and leave this valued water resource to our state's irrigators and rehabilitation of the river. We must look more closely at desalination plants and place more focus on harvesting the city's rainfall, recycling, making our water distribution more efficient as well as getting the right price structures in place. Adelaide should be securing its own core independent water supply and possibly building three or four water desalination plants over the next five years, harnessing stormwater and increasing recycling.
Gobbett rightly points the finger at the Rann state government. He says that the State Government's blinkered focus on cutting water consumption by merely turning off the taps is hampering SA's long-term ability to solve the water crisis, and:
The State needs to adopt a new mindset to solve its water crisis. By putting all our eggs in the Murray basket, we are closing our minds to market-based and technological solutions on our doorstep. There is also no certainty the other states will continue to let the water flow even if it rains heavily. We should be under no illusions – they will look after their own businesses, farms and householders first for power and water.Already water restrictions in the eastern states have reduced their electricity generation. We need an independent solution.
What we have is an incompetent Government that is unable to plan long term for water infrastructure investment . The State Government's long-term strategy for the state's water supply has been to pray for rain while tinkering around the edges. This has resulted in the imposition of harsh water restrictions as a means of conserving existing supplies.

i wonder if there are any circumstances short of imminent death that will awaken ozzies to the need for democracy.
on present form, they'll be saying: "please sir, may we have food/water/a place to sleep" right up to the end. it can only be genetic.
