Tree Root Intrusion in Sewer Pipes: Causes, Inspection, and Removal
2026-08-31
Tree root intrusion occurs when roots enter underground sewer or drainage pipes through cracks, defective joints, service connections, or other openings. Root growth can restrict the flow area, collect debris, and eventually cause blockages. CCTV pipeline inspection is commonly used to identify and locate root intrusion. Depending on the severity, roots can be removed using mechanical cutting, high-pressure water jetting, or robotic pipe cutting equipment. If structural defects remain after root removal, trenchless rehabilitation such as CIPP may be considered to prevent recurring root intrusion.

UV CIPP, or ultraviolet cured-in-place pipe, is a trenchless pipeline rehabilitation method that uses ultraviolet light to cure a resin-impregnated liner installed inside an existing pipeline. The process typically includes pipeline inspection, cleaning, liner installation, inflation, UV curing, connection reopening, and final CCTV inspection. UV CIPP can provide controlled curing, efficient installation, and reduced surface disruption compared with conventional open-cut pipeline replacement when the existing pipeline is suitable for rehabilitation.
Trenchless pipe rehabilitation repairs or restores underground pipelines with minimal excavation. Common technologies include cured-in-place pipe (CIPP), UV CIPP, pipe lining, robotic cutting, and other rehabilitation methods. CCTV pipeline inspection is typically used before and after rehabilitation to assess pipeline conditions and verify repair quality. Compared with traditional open-cut replacement, trenchless rehabilitation can reduce surface disruption, shorten construction time, and lower the impact on roads, buildings, and surrounding infrastructure.-
