|Description:||This historic 1922 drawing depicted an improperly constructed “drilled” well for municipal use. An obvious hazard was the location of the privy to the right of the station, which was shown draining downhill toward the pump house. It also revealed a dangerous arrangement of the suction-type pump, which had been located in a pit that drained overflow to a sewer. However, with this configuration, there was the potential for contamination should the sewer ever back up, due to flooding.|
The descriptive information accompanying this drawing referred to a governmental publication, which dealt with this topic. The specific citation was, “Minnesota State Board of Health, Division of Sanitation, Water Supplies and Sewerage Systems for Municipalities, March, 1923, p. 14”. This was one of a series of instructional images used by the Minnesota Board of Health, in order to train its state public health workers. The purpose of these images and the 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.
