1951 Press Photo Plant workers clean silt from reservoirs along the Mississippi.

These water plant workers are cleaning the silt from tanks in which the city's drinking water is produced out of the muddy Mississippi. Plans now call for an automatic system of cleaning these tanks. This will eliminate the need for shutting the tasks for periodic cleanings, thus increasing the water-producing capacity of the plant.
