Description:This 1936 diagram, which had been digitally enhanced and colorized, illustrated the means by which polluted water might be transferred from an elevated container, at one level, to a container on a lower level, and the method of preventing such contamination.
The purpose of these images and the requisite training was focused on protecting water supplies from bacterial contamination due to incorrect disposal of waste, such as sewage, in order to prevent water-borne diseases. The descriptive information accompanying this drawing referred to a governmental publication, which contained instructions describing how to correctly place and build such a device. The specific citation was, “Minnesota State Board of Health, Plumbing in Relation to Public Health, 1938, p. 20”.
