How can excessive tree roots affect a septic system?

Excessive tree roots can significantly impact a septic system by infiltrating and clogging pipes. The roots of trees and larger plants naturally seek out water sources, and in the process, they can grow towards the septic tank and the accompanying drainage pipes. Once these roots penetrate the system, they can obstruct the flow of wastewater, leading to backups, reduced efficiency of the septic system, and, in some cases, complete system failure.

This clogging results in an inability for the septic system to effectively handle waste, which can cause various issues including unpleasant odors, surface pooling of sewage, and ultimately costly repairs or replacement of the septic system. Proper maintenance and the strategic placement of trees and plants can help prevent these types of issues.
