When is the City Responsible for Sewer Lines and Plumbing Repair?

Sewer line backups and replacements are plumbing nightmares that can be both tedious and expensive. Homeowners are obviously responsible for their own residential plumbing, such as a clogged sink drain. However, what about problems with the sewer system past your property line, or problems with a sewer line from the house to the street? Basically, you want to know, when is the city responsible for sewer lines and plumbing repair?

There are some cases where the city or municipality will be held responsible to fix, while others will leave the homeowner responsible.
