On my latest visit to the Toronto Archives and the Toronto Public Library Archives, I found some very interesting photos of the Toronto sewer system and those who worked on it.

The images date back to the late 1800s and show some of the workers throughout the years as well as the design and materials used on our early sewers.

Take a look at the pics and let us know anything interesting you notice via social media.
