The Role of Microbes in Your Septic System

How the Septic System Works

The septic system actually involves a simple process. We can summarize how the septic system works in three stages.

First, waste and wastewater travels through your household drains and into the septic tank where they split into three layers. There is a top layer of scum, a middle layer of liquid effluent, and a bottom layer of solid waste.

The wastewater flows through the outlet pipe and distribution box toward the drain field. There, the wastewater filters through the soil for treatment.

Microbes in The Tank

There are bacteria in the septic tank that play a crucial role in making the most out of the septic tank’s limited capacity. Aerobic bacteria uses oxygen to digest and break down the top layer of scum while bacteria at the bottom of the tank use anaerobic digestion to break down solid waste into sludge. Almost half of the solid waste is turned into gases such as methane, hydrogen sulfide, and sulfur dioxide. As you can guess, this saves valuable space.

There are also bacteria in the drain field. Anaerobic bacteria and other microbes in the soil form biofilm, a slime layer that holds bacteria together. As wastewater flows out of the perforated pipes in the drain field, the biofilm catches organic waste and removes pathogens.
As you can see, the bacteria both saves space and removes harmful material from the wastewater so that the soil and underground water sources are not contaminated. This is why you should take great care of the bacteria.

Taking Care of the Bacteria

You want the bacteria to be in their best shape. The last thing you want to do is threaten their life, but that is exactly what you would be doing if you poured harsh chemicals and chemical cleaners down your drains.

You can also overwhelm bacteria if you flood the system with wastewater. This is why we recommend homeowners stagger their water usage, opt for water-efficient appliances and plumbing fixtures, and stay away from heavy water users such as a jacuzzi.
