Not normally. Your home insurance was designed to repair or replace your home if something covered happens to it. Usually, anything below ground isn't covered. Now, if your home is destroyed and the insurance company rebuilds your home, they will usually pay to hook your sewer up, but not to repair or replace the pipes. if you think about the things that can happen to a home, a sewer pipe really can't have those things happen to it.
My big question here is: what the heck happened to your sewer pipes that you want covered? Insurance is designed to repair damage that is sudden and accidental. There aren't many things you can do to a sewer pipe that are sudden and accidental. About the only thing I can think of is if someone working underground hits a sewer pipe and breaks it. In this case the company working there is responsible for any damage they may cause.
