Back in 1887, Fred Eaton, the City Surveyor, drew up plans for a proposed sewer system for the City of Los Angeles.  He estimated a cost of $1,000,000 to construct the proposed system.  A report from consulting engineer Rudolph Hering supported Eaton’s work and suggested spreading fields for the system.

I like how everything flows to one location, “Outfall Sewer”, at the lower left corner of the map.  I wonder if some of that infrastructure is still there today?  Check it out on the Huntington Digital Library site.

For you high-res junkies, here you go!
