This historic 1913 photograph depicted the interior of a hypochlorite plant located in Duluth, Minnesota. The image revealed some of the details of the piping, and the control box machinery inside the facility. The device was an integral component of the city's water filtration system. This was 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.
