I used to work for a company that cleaned and inspected pipe, primarily sanitary sewers. Cleaned and inspected pipes as small as 4" and as large as 110". When we cleaned the 110" pipe, we actually lowed an ATV down into the sewer with a modified snow plow on the front to push the solids to a manhole. Did that job for about 15 years.
SO, as bad as your story sounds, I've got several that make yours seem like a sunny walk in the park.
And these days I work at a sewer treatment plant, it's not often but we have times every now and then that we have to do a nasty job. Thankfully it's usually a controlled mess and we have of PPE on.
