In the old days dogs and rats were used to clean sewers.

In the early years, before specialized equipment came along to help clean sewer piping, one unique approach to cleaning a drain was practiced:

sewer cleaning historyFirst a rat was caught and put in a cage which was set down in the invert of the sewer at a manhole.

Second, 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 into the sewer. The Early Years of Sewer Maintenance.
