Sewer Line Replacement in Carrboro, NC

Carrboro's lines: what's in the ground

OWASA treats wastewater for both Carrboro and Chapel Hill at its Mason Farm plant, which handles about 7 million gallons a day through a network of roughly 350 miles of sewer. When OWASA's smoke testing turns up defects in a private lateral, it asks the owner to fix them. That makes the pipe under your yard your project, though OWASA doesn't spell out the exact point where its part begins, so check before you sign anything.

Housing here is a mix. The median Carrboro home dates to 1988 and about 29% were built before 1980, according to ACS 2019-2023 estimates, with a big share from the 1980s. Then there are the historic mill houses in the Carrboro Historic District around Shelton Street, which are the most likely to still drain through old clay or cast iron. The 1980s homes generally have plastic pipe, so when they fail it is more often a belly from settled soil or a crack from later digging.

Warning signs

• Backups that come back soon after a cleaning
• Water rising in the shower when a toilet is flushed
• A sewer smell outside near the cleanout
• Patches of grass that stay green or wet over the line

Timing and planning

Settle the permit question early. Carrboro's Inspections Division requires a permit to install, alter or repair a service system, and applications go through the Town's PIPER online portal. Some addresses near town fall under Orange County or Chapel Hill instead, so the Town suggests using its GIS "In Carrboro" tool to check jurisdiction first. If you already know the line is failing, scheduling the work in drier weather keeps trench restoration simpler than waiting for an emergency backup.
