Description:This historic diagram, which had been digitally enhanced and colorized, depicted a cross-sectional representation of a properly constructed “flowing” well that was being used as a farm’s potable water supply. The pipe was sunk far into the ground allowing for maximum natural filtration offered by the surrounding rocks, sand, and gravel. The end of the pipe was protected against damage, while any water overflow was directed through a drain away from the water source. The receptacle used for capturing the water never touched the sources, thereby, reducing the chances for contamination.
Published in 1919, this was one of a series of instructional drawings used by the Minnesota Board of Health to train its state public health workers. The purpose of this and other like images, and the training was focused on protecting potable water supplies from bacterial contamination. The descriptive information accompanying this drawing referred to a governmental publication with instructions describing the correct placement and construction of a detached home privy. The specific citation was, “Minnesota State Board of Health, Water Supplies and Sewerage Systems for Farm Residences, July, 1919, p. 25”.
