Why should the area around a septic system be kept clear of heavy vegetation?

Keeping the area around a septic system clear of heavy vegetation is crucial to prevent roots from invading the system. Roots from trees and shrubs can grow into the septic tank and the drainage field, leading to potential blockages and damage. When roots penetrate these components, they can obstruct the flow of wastewater, resulting in system malfunctions and costly repairs. Additionally, the presence of roots can disrupt the intended function of the septic system, which relies on a delicate balance of soil and microbial activity to treat and filter wastewater properly. Maintaining a clear zone around the septic system helps ensure its effective operation and longevity, safeguarding the investment and protecting both the environment and public health.
