The sewer lateral is yours
The private sewer lateral, the pipe carrying wastewater from your home or business to the public sewer, is the property owner's responsibility. Columbia Water sends letters to owners when it finds a broken or defective lateral and encourages them to have a plumber fix it, because defects let stormwater and groundwater into the system and can lead to backups.
