This is an unusual map of the city of San Francisco that documents existing and proposed water supply infrastructure of the Spring Valley Water Co.

The most striking feature of the map is its illustration of the topography of the city, elegantly achieved by a combination of contour lines and color-coding. The power of the Spring Valley Water Co. and the extent to which San Francisco relied on its monopoly is on full display, with existing and proposed reservoirs, existing and proposed pumping plants, and existing and proposed conduits all plotted.

The only example of this map we have ever seen.


The Union Litho. Co.

The Union Lithography Company was a commercial printing house based in San Francisco and active in the first half of the 20th century.
