I own a small business and have been told my sewer line that leads to the city's main sewer line needs replacing. The cost is so much, is there anything I can do to get the city to help?

It's a long shot but can't hurt to ask the city. Maybe they can suggest a less expensive repair other than total replacement of the line. Who told you that replacement was the only option and based on what type of inspection? Did you get a second or third estimate?
