A sewer cleanout is a pipe covered by a cap that rises from the sewer lateral line to about four inches above ground level near the property line. If the cleanout is buried or hidden, the property owner is responsible for making it readily accessible. If a cleanout is not present, one should be installed at the property line by a licensed plumber.
The county is responsible for maintaining the wastewater lines from the main trunk to the sewer cleanout at the property line. In the event of a sewer backup, call the county first at 410-535-1600, ext. 2329, and a technician will diagnose the problem. If the sewer line and main are found to be clear or if the location lacks a property line cleanout, the property owner is responsible for repairing the blockage.
