Australia's Critical Water Shortage

[Bob Moseley (RIP)]

Hi all - one of my good mates has just sent me these images of our country's latest effort regarding water conservation. Impressive isn't it. He also informed me that two people on the payrole, at $28 an hour, are local aboriginals who are following the excavations to make sure no bones or artifacts are dug up. Good job if you can get it. I'm not sure what the guy standing next to the excavator is doing, maybe dust control.

Hi all - as a followup, my mate obtained these specific instructions from the contractors. These would negate any margins of error.

PIPE SPECIFICATIONS

1. All pipe is to be made of a long hole surrounded by metal or plastic.
2. All pipe is to be hollow throughout the entire length, do not use holes of different length than the pipe.
3. The internal diameter of the pipe must not exceed the overall diameter otherwise the hole will be on the outside.
4. All pipe is to be supplied with nothing in the hole so that the water, steam or other stuff can be put inside at a later date.
5. All pipe should he supplied without rust as this can be more readily applied at the job site. Note some suppliers are now able to supply pre-rusted pipe if available in your area. This product is recommended as it will save a great deal of time on the job site
6. All pipes over 500ft (153m) in length should have the words “Long Pipe” clearly painted on each end so the contractor will know it as a longer pipe.
7. Pipe over 2 mile (3.2km) in length must have the words “Long Pipe” painted in the middle so the contractor will not have to walk the entire length of the pipe to determine whether or not it is a long or short pipe.
8. All pipes over 6 inch (152mm) in diameter must have the words “Large Pipe” painted on it so the contractor will not mistake it for a small pipe.
9. Flanges must be used on all pipes. Flanges must have holes for bolts quite separate from the big hole in the middle.
10. When ordering 90, 45 or 30 degree elbows be sure to specify right or left hand otherwise you will end up going the wrong way.
11. Be sure to specify to your supplier whether you want level, uphill or downhill pipe. If you use downhill for going uphill the water will flow the wrong way.
12. All couplings should have either right hand or left hand threads but do not mix the threads otherwise as the coupling is being screwed on one pipe it is being unscrewed from the others.
13. Where pipe is being installed in a “non pressure situation (e.g. gravity return over flow or drain) the word “Top” must be painted in a prominent position so that the water runs only in the bottom of the pipe
14. The word “End” showing where the hollow pipe stops and solid pipe begins shall be clearly marked on all such sections. No length shall have an “End” more than halfway from the middle or more than one “End” per length.
15. Each pipe length must be marked with an arrow denoting the direction of flow on each end.
16. Pipes will be either “Uni-directional” or “Bi-directional and in such cases will bear the arrow symbol with the arrow head pointing to where the conveyed material is supposed to go. N.B. care must be taken to see that Bi-directional pipe does not have arrowheads pointing toward each other or a “no flow situation will develop with the resultant high pressure causing a permanent deformation or rupture. Similarly, arrowheads should not point away from each other or the converse situation will develop when the centre hole will stretch (with consequently reduction in diameter) and flow stranguration will occur.

Bob..
Those spec's must have been issued by the Australian military..who got them from the Canadian Military..who got them from the U.S Mil...........etc..

Great specs..

Mmmmmmm what can I say it all seems a bit of a pipe dream,its dream time, better have another go at that flagon,

It's all common sense really. Obviously the British Military haven't adopted them yet.
