How Does a Septic System Work?


Most of us don’t think about how our septic system works. In fact, most of us take it for granted. However, it is a very complex system that does a very necessary job.

Without a septic system, we would not have nearly as an effective a method of safely disposing waste. In this video, you will learn more about the systems and engineering behind a septic system.

A septic system is composed of two compartments. Everything first goes into the initial compartment. Solids then either sink to the bottom or float to the top. In the middle, dirty water is drained into a second tank. The second tank is connected to a pump filter that pumps water out of that tank about every twenty minutes. This water goes to a treatment pod where it is cleaned. The water drips over a stratum which houses bacteria. These bacteria are crucial because they convert ammonia in the water into nitrogen. The water then continues to drip to the bottom of the pod where it is transferred to the sand filter. The sand filter then disperses the water safely into the ground where the water reengages with the water cycle.
