How can landscaping affect the efficiency of a septic system?

Landscaping can significantly impact the efficiency of a septic system, particularly through the interaction of plant roots with the septic infrastructure. Roots from trees and shrubs can infiltrate the septic system, including the pipes and the drainfield, potentially leading to blockages or damage. This infiltration can disrupt the flow of wastewater and inhibit the proper functioning of the system. If roots penetrate the pipes, they can cause leaks or clogs, which can lead to system failures and costly repairs.

The correct understanding of this dynamic highlights the importance of careful planting around a septic system. It is advisable to select landscaping plants that have shallow root systems and to maintain sufficient clearance around the system components to ensure optimal performance and longevity of the septic system.
