What is the primary function of bacteria in a septic system?

The primary function of bacteria in a septic system is to break down organic waste. In septic systems, these microorganisms play a crucial role in the decomposition process by digesting the solids that accumulate in the septic tank. This biological activity is essential for the proper functioning of the system, as it helps convert waste into simpler substances that can be further processed by the soil in the drain field.

Bacteria break down organic materials through a series of biochemical reactions, reducing the volume of solids and preventing the system from becoming clogged. Their operation minimizes odors and reduces the risk of system failure by facilitating the effective treatment of wastewater. This decomposition process is why maintaining a healthy population of bacteria is necessary for the longevity and efficiency of septic systems.
