How can trees and shrubs affect an OSSF?

When considering the impact of trees and shrubs on an On-Site Sewage Facility (OSSF), tree and shrub roots can indeed pose a significant threat. These roots have a natural tendency to seek out water sources, which can lead them into the underground components of the sewage system. As the roots infiltrate the system, they can cause structural damage to pipes, infiltration into septic tanks, and blockages that can result in system failure. This can lead to expensive repairs and environmental issues, underscoring the importance of proper landscaping around OSSFs.

While trees and shrubs may contribute positively in various ways, such as improving system efficiency through shade or aiding in water balance, these potential benefits do not outweigh the risks posed by root intrusion and damage to septic systems. Understanding this is crucial for the maintenance and longevity of an OSSF.
