Septic vs. Sewer: What Chapel Hill Homeowners Should Know

Most homes within Chapel Hill proper connect to OWASA's municipal sewer system, but properties toward the rural edges of Orange and Chatham counties, including much of the area around Fearrington Village, rely on private septic systems instead.

How to Tell Which You Have

Check your OWASA bill or property records; if you don't have a sewer line item, you likely have a septic system. A septic tank access lid in the yard is another clear sign.

Maintenance Differs Significantly

Municipal sewer connections require little homeowner maintenance beyond keeping the lateral line clear. Septic systems need periodic pumping, typically every three to five years, and more careful attention to what goes down the drain.

Warning Signs Differ Too

Sewer backups often trace to root intrusion or a collapsed lateral line, while septic backups more often mean a full tank or a saturated drain field.
