Root Damage

Roots are a common problem in side sewers. Older concrete and clay pipe side sewers that were not constructed with watertight joints are especially at risk for root damage. Roots can crack pipes and cause sewer backups.

Recommendation

Routine inspection

Minor root

Minor root intrusion.

Typically, minor root intrusions produce no effect on the working function of the pipe.

Inspect three to five years after original inspection.

Routine inspection

Moderate root

Moderate root intrusion.

May or may not affect the working function of the pipe. Root intrusions will likely increase in severity over time.

Inspect three to five years after original inspection.

Routine inspection & cleaning

Severe root

Severe root intrusion.

Severe root intrusion, obstructing 50% or more of the pipe can or will affect the working condition of the side sewer.

Inspect every one to two years. Perform routine cleaning.
