Learn how it Works – Basic Processes that Occur inside a Septic Tank

Being the man of the house requires from you to know at least something about every particular system that you have installed in your house and in its vicinity. Whether it’s heating, cooling or water pumping system you need to know the basics in order to avoid humiliating yourself when you encounter a problem with one of those systems. Imagine calling for a handyman to fix something and trying to describe the problem without any knowledge of how that system works. In water processing and pumping systems like the ones used by septic tanks, we have four basic principles on which a septic tank processes water.

Water initially passes through an inlet. This septic water is full of scum, grease, oil, and sludge. For water to exit the tank into the fields it needs to be processed. This occurs due to a chemical process that happens inside the tank where the sludge goes down on the bottom, water stays in the sedimentation zone and scum floats on top. This is called the separation process where natural chemical compounds are decomposing and rearranging its structure.

This is possible due to the structure of a septic tank. Basic septic tanks have an outlet, inlet, vents and two chambers inside the tank that are used for separations of septic water. Without this exact structure, natural chemical processes that occur once the septic water goes through an inlet wouldn’t be possible. Due to vents that allow limited amount of oxygen to enter, than then acts as a catalyst for the process of separation to begin, water inside the tank is able to stay in the sedimentation zone. After water is separated a certain amount of it goes into the second chamber that is partially opened.

In the second chamber, the amount of sludge and scum is brought to a minimum allowing larger quantities of purified liquid to exit via outlet into the fields. Now that you know the basics of how septic tanks work you will be able to determine and describe a problem you are encountering with the septic system with greater ease than before.
