What can damage the integrity of the septic system over time?

Heavy machinery over the system area can cause substantial damage to the integrity of a septic system. When heavy equipment is operated on or over the septic system, it can compact the soil, leading to reduced permeability. This compaction can hinder the natural function of the soil in filtering and treating the wastewater, potentially causing backups and system failure. Additionally, the weight of heavy machinery can physically damage components of the system, such as tanks and pipes, further compromising its ability to operate effectively.

In contrast, regular maintenance is essential for ensuring the longevity and proper function of a septic system. This includes tasks like pumping the tank and inspecting components to prevent issues before they become severe. While the use of bacteria additives can be debated in terms of necessity, it generally does not damage the system if used appropriately. Rainwater infiltration, although it can affect the system's capacity and function, typically does not cause direct physical damage in the same way heavy machinery does.
