Carrboro's housing and sewer

Carrboro is a former mill town just west of Chapel Hill, and its houses span a long stretch of time. Census survey figures put the median home at 1988, with a large 1980s share and about 29% built before 1980. The oldest are the mill houses in the downtown historic district around Shelton Street, where original drain lines may be cast iron or clay. Newer neighborhoods from the 1980s on are mostly plastic pipe, which rarely fails on its own but still collects grease and soap residue.

OWASA provides sewer service for the Carrboro-Chapel Hill community and treats it at the Mason Farm plant. The public main is OWASA's. The lateral from your house to the main is the owner's, and OWASA asks owners to repair private laterals when its smoke testing finds defects. If a repair turns up after cleaning, check jurisdiction first: Carrboro's Inspections Division handles permits through its PIPER portal, but some nearby addresses fall under Orange County or Chapel Hill instead.

Options for a line that keeps clogging

Signs it's time to call

• You've cleared the same drain more than twice this year
• Sinks and tubs on the lowest level gurgle or back up together
• A sewer smell near the cleanout or a floor drain
• Water comes up in the tub when the washer drains

Seasonal notes

Root intrusion in older clay laterals tends to show up in the warm months, when trees are growing hard and seeking water. Kitchen lines often clog in late fall and over the holidays, when more cooking means more grease down the sink. If your house has a history of either, scheduling a cleaning ahead of those stretches is easier than dealing with a backup at a bad moment. If OWASA's smoke testing ever flags a defect on your lateral, a camera pass after cleaning will show the plumber exactly where it is.
