# Sewer Lateral

A sewer lateral is the private pipe that connects a building's plumbing to the public sewer system, usually owned and maintained by the property owner.

## Why it matters

Cracks, root intrusion, bellies and collapses in laterals can cause backups and costly excavation. A camera inspection shows pipe condition without digging. Buyers often order one for older buildings and restaurants.
