aboriginal tunnels for water...

Vishwanath Srikantaiah, 53, is a water activist and has been working in the space for over 27 years. Mr. Vishwanath is also a columnist for The Hindu, who writes weekly columns about water preservation. A Civil Engineer, and Urban & Regional Planner by profession, he has worked with HUDCO(Housing and Urban Development Corporation) for 14 years. Vishwanath or popularly known as @zenrainman, started a club while he was in HUDCO. “We started a small group called the rainwater club in 1994. We used to collect documents and information about rainwater harvesting and put it up on public domain.”

MY FINAL COMMENT: The only geographical area and civilization NOT to have extensive dug wells is the original people of Australia. Incidentally they did not have the wheel too. Is the well and the wheel connected? - zenrainman
The hypothetical connection between wells and the wheel is a rather questionable one. What qualifies as a well - naturally found between rocks (surely this must have some value in an arid zone), hand-scooped or dug with tools? The aboriginal concept of a well is often aligned with water tunnels. And, as Aboriginal had no need for a wheel, the whole hypothesis seems to stumble away from any possibility of validity. Further, wells were not even necessary to provide for crops. Perennnial crops, such as kangaroo grass, did not need ploughing and did not generate a loss of topsoil. Just random rain was enough for the crop. No need for irrigation. Finally, what does this hypothesis hope to achieve? One civilisation is more advanced than another? One civilisation progresses faster than another? Surely, comparing water management skills of different societies would have more value, improving modern society's water management understanding. 

FIRST MACHINE: The first known reference to a machine dates to the ancient Near East circa 5000 BC, when it was first used in a simple balance scale, a lever.  In ancient Egypt circa 4400 BC, a foot pedal was used for the earliest horizontal frame loom. In Mesopotamia (modern Iraq) circa 3000 BC, the shadouf, a crane-like device that uses a lever mechanism, was invented for irrigation.  In ancient Egypt technology, workmen used the lever to move and uplift obelisks weighing more than 100 tons. Archimedes referred to the lever in the 3rd C B.C. So a connection between the wheel and water seems even more remote, the closest being a shadouf.
