"[Lot of 2] System of Sewerage for the City and County of San Francisco Sewerage Districts, Main Sewers and Sub-Mains of Districts... [and] ... Sewerage Districts Sewered on the Separate System Location of Sewers and of Pumping Stations",

These two large, striking maps were produced by C.E. Grunsky to document the proposed new sewer system for the city and county. The first map highlights the storm water conduits and the "combined" sewer system, while the second is focused on sewers and pumping stations on the "separate" system (which is mostly along the eastern edge of the city). Both maps show planned streets in San Francisco Bay that would be constructed once infilled. Lithographed by Britton & Rey.
