LEONARDO DE VINCI'S WATER PUMP INVENTION
WATERHIJMACHINES
THERE IS DUTCH TEXT ON THE BACK
Leonardo did much work with water pumps and wells. During Leonardo's time man
had already built up considerable knowledge in these areas and Verrocchio was an
experienced hydraulic engineer; it was him who first introduced Leonardo to the subject.
Though much of his work was in no way new, or revolutionary, he did come up with a
number of improvements on items like the Archimedean screw. Leonardo's version
had much less seepage and friction, so was more reliable. Leonardo designed a
waterwheel which, through the use of two of these screws, would be able to fill a
water tower, perhaps for the town water supply. Another possible use for Leonardo's
design was the draining of swamps.
