Question: 1 / 400

How can tree roots affect a septic system?

They can invade and damage pipes, leading to blockages or system failure

Tree roots can significantly affect a septic system primarily by invading and damaging the pipes, which can lead to blockages or even system failure. The roots are naturally drawn to the moisture and nutrients present in the effluent from the septic system. As they penetrate the pipes, they can create clogs that impede the flow of wastewater, resulting in backups or overflows. Additionally, if the roots continue to grow within the system, they can cause physical damage to the pipes themselves, leading to costly repairs and potential system replacement. Maintaining healthy distances between large trees and septic components is crucial to avoid these issues.
