I’m a Plumbing contractor, is this your house you are talking about?

If a house lasts long enough then the line in the yard will have to be replaced, just as the line to the septic eventually gets replaced, but other than that, the septic is the one that requires routine maintenance, not a sewer line.

One installs a sewer line from the house to the property line when the house is built, and that should be it for 50 or 70 years.

The pipes lasted over 60 years. During the drought, tree roots ate the clay pipes. The house was originally built for septic, so when the pipes were replaced it was tricky to find the best "path" to the street line, which is a longer distance than septic would be. The original sewer work wasn't all that efficient. I'm up to code now, and the plumbing service stands by their work.

Since I always, since childhood, had septic, I am very careful about what goes in the system. So for me, it (and being stuck with town water) seems like punishmet for other people's careless use.
