There are numerous types of sewer pipe materials.
One is "Orangeburg", made from cellulose fiber and tar.
It deteriorates after....50 years!
(I'm not suggesting you have this; just a heads up)
History of the pipe here:

and:

Problem, as seen from Tempe, AZ:

Quote: "the average person should not be allowed to do..."
In many cities/counties, he wouldn't be allowed to do it
without a permit.
Not only are injuries possible, but every utility imaginable
may be buried nearby. In 1950 the prevailing practice was to
bury the city water line in the *same* trench as the sewer lateral.
Oh, the water line may have been elevated a foot or so on a "ledge",
but it was in the same trench. Running a trench machine thru that
is almost a guarantee of a water line break.
