Operation
The region of Banská Štiavnica lacks significant sources of flowing surface water. That is why tajchy were designed to store water derived from precipitation. Channels with the overall length of 72 km diverted water from the rain and melting snow to sixty reservoirs. The whole system could accumulate 7 million m3 of water. The water then flowed through 57 km of channels to water wheels, which powered seven pumps equipped with a pendulum-action system. The pumps removed excess groundwater from mines and the water wheels later also provided energy for mining, processing, metallurgy, and mills.

Famous quotes containing the word operation:
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
“Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.”
—Francis Bacon (1560–1626)
“You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
—Thomas Henry Huxley (1825–95)
