lCANBERRA, AUSTRALIA — Australian Prime Minister John Howard says it will take $7.8 billion dollars (US) to fix the drought-plagued continent’s water supply, a January 25 Associated Press story on MSNBC reported.
All eyes should be on Australia and its drinking water problem because – guess what – your country might be next.
Technological advances stemming back to the Victorian era in England are seriously catching up with us.
1) MIFSLA. That stands for mix first separate later. Mixing grey and black water together, then cleaning it, letting it out into natural watercourses – or worse – letting it out into the sea where is is irrecoverable in principle – only to turn it into drinking water which you use to flush the toilet may have worked back then.
Today it requires a lot of work, a lot of energy and uses too much of the available water.
2) Piped water. Piped water, although more environmentally friendly as drinking water than bottled water, has to be chlorinated to travel down the pipes. Chlorination is associated with carcinogenic bi products. No technical solution to that seems to be on the horizon expect for placing POU (Point of use) purifying devices in every home. (See link for details of one solution)Howard, calling for radical and permanent changes, tsays of the he water shortage “it is one of the greatest challenges of our time, …..the current trajectory of water use and management in Australia is not sustainable.”
