My sewer is backing up into my basement. What should I do?

This could be the result of two things: 1—There is a blockage or restriction in your lateral (your private line from your house to the City’s main sewer line), or 2—There is a blockage or restriction in the City’s main sewer line. If a backup happens, it is a good idea to call the City to have an employee come and check our main line for problems. If the City’s main sewer line is not blocked, then you will need to call a plumber to look at your line.
