Interpreting Water System Maps

Example of a portion of a water system map

In many editions of fire insurance atlases of large towns or cities, there was a separate map, frequently an inset but sometimes rather substantial in size, showing the water distribution system. Such a map might be accompanied by a description of pumping station equipment, pressure, sizes of mains and water lines, the types and distribution of fire hydrants, and so forth.
