Introduction to Aerobic Septic Systems: Basic Overview and Functioning

Aerobic septic systems effectively and efficiently manage wastewater from homes, businesses, and other establishments. They are often used as an alternative to traditional septic tanks. An aerobic septic system relies on mechanical, biological, and chemical reaction to break down solid waste and material and purify the effluent for discharge into the environment.

Aerobic septic systems comprise a tank, an aerator, and a pump chamber. The tank collects the wastewater that enters and holds it for some time to allow solids to settle out. This is necessary for the material to be broken down into smaller particles.

The aerator injects oxygen into the wastewater, creating an environment where beneficial bacteria can thrive and break down organic matter. Finally, hot water from the pump chamber pumps effluent out to the drain field, which is filtered before being discharged into the environment.
