In the early years, before specialized equipment came along to help clean sewers, one unique approach to cleaning a sewer was practiced:
First a rat was caught and put in a cage which was set down in the invert of the sewer at a manhole. Next a rat terrier dog was put into the next downstream manhole; with a tag line tied to it. When the dog sensed the presence of the rat, he would run up through the sewer towards the cage … dragging the tag line with him.
The dog was then lifted to the surface and the tag line used to pull through a rope — which, in turn, was used to insert heavier tools, etc., into the sewer. The Early Years of Sewer Maintenance.
