Thanks for this posting. There is certainly a rich array of collected materials by Jon on www.sewerhistory.org ; I hope this work will continue.

I noticed a rather graphic display of how engineers were thinking a hundred years ago along the Pacific coast near Los Angeles.

The History of Sanitary Sewers says
"Over the past twenty years, Jon Schladweiler, the Historian of the AZ Water Association, has researched and collected materials related to the history of sewage conveyance systems. Many of these have been displayed in a traveling exhibit entitled “The Sewer History Exhibit” The overall collection of sewer history materials covers the era from approximately 3500 BCE through the 1930s CE. The purpose of this website is to house this dynamic collection of materials about the evolutionary development of sewers over the past 5500 years, and to provide a location for the sharing and distribution of information to others. The donation of additional photos, sketches, articles, books, or other sources of historical information on the history of sewers is appreciated. This website is an educational, non-profit endeavor. Its intent is to offer some insight into the history of sewers and the role its operators, engineers, and builders have played in making our environment, homes and communities better and healthier places to live.
