If you go to school in the city, you probably don’t give much thought to the cool water that flows from the water fountain with the press of a button.
Now put yourself on the prairie in a one room schoolhouse in the late 1800’s and the picture changes.
Well – that’s a deep subject, back then there was no water department, no rural water district. Instead, the water supply for each homesteader was independent from his neighbor’s down the road. Everyone dug their own well, and so too did the school.
The depth of a well in Kansas varies greatly according to location. A well near a river or creek might need to be dug as little as 20 feet or even less to strike water, but a well for a little school house standing on a high lonely hill might need to go down much further, sometimes, more than a hundred feet before striking water. (If you want some facts and figures on wells in Kansas for the year 1895, check out The Report of the Kansas State Board of Agriculture, first quarter, page 109. Notes on some Kansas wells. You can also visit the World’s largest hand dug well in Greensburg, Kansas at at depth of 109 feet, completed in 1888.) BigWell.org
In the earliest days, the water was drawn with a pail on a rope and pulley. But it didn’t take long for a new-fangled invention called a water pump to make life easier for the school marm and her thirsty kids.
How did the pump work?
It is all a matter of air pressure. When you stick a pipe down the well into a pool of water at the bottom, air inside the pipe pushes down on the water in the pipe, and air outside the pipe is pushing down on the water in the well, which in turn pushes up. All is in balance.
But now let’s say little Johnny or Timmy, Susy or Jane begins to vigorously pump the handle sucking out the air inside the pipe. (At the soda fountain, Johnny and Susy creates the same reaction with their straws in a root beer float.) The water pressure in the well remains the same, but there is no counter acting force pushing the water down the pipe, so it begins to gush out the faucet.
Note, that the vacuum pump only works to a depth of 34 feet more or less, depending on altitude, since that is when the atmospheric pressure in the well reaches equilibrium with the vacuum in the pipe. Want the details?
