This historic 1912 photograph revealed some of the interior machinery inside a hypochlorite plant in Stillwater, Minnesota. This device acted as an integral component of the water filtration system for the town’s potable water supply. This is one of a series of instructional photographs used by the Minnesota Board of Health to train public health workers. The focus of the images, and the training effort was to promote sound practices involved in protecting potable water supplies from bacterial contamination.
