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.
If professionals replaced the sewer line in your yard, then you should be good for 75 years or so, with no further service needed.
I’ll take sewer over septic any day, septic is a problem that needs maintenance and attention and is a nightmare to replace.
