There is sewer backing up in my house, what do I do?

Call the Sewer Department (603) 485-5600 immediately. Someone will come out to see if there is a blockage in the main line or the homeowner's line. If the blockage is in the main line, the sewer department will clear the blockage. If the problem is in the homeowner's line, it is up to the owner to call a plumber and correct the issue.
