Sewer History

Over the past fifteen years, Jon Schladweiler, the Historian of the Arizona Water & Pollution Control 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 Collection Systems Historical Photo and Artifacts Display". The Sewer History Exhibit and website houses a dynamic collection of material about the evolutionary development of sewers over the past 5500 years.  This 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 may have played in making our environment and communities better places to live.

The WEF Collection System Committee (CSC) assists in sponsoring the Sewer History exhibit and website.
