Why Microbes and Bacteria are Essential for Your Septic System

26 September 2023

Septic tanks play a vital role in disposing of wastewater in areas without access to municipal sewage systems. However, these underground waste processors’ fascinating science is often a mystery.

In this article, we will highlight the indispensable role of microbes and the importance of diligent maintenance to prevent the need for septic tank repairs that often.

The Importance of Microbes and Bacteria

Have you ever pondered the secret behind your septic system’s cleanliness? The answer lies in the remarkable work of microbes and bacteria, often overlooked but essential. These microscopic organisms diligently break down the waste that accumulates within your septic tank, ensuring optimal functioning.

In your septic tank, the wastewater naturally separates into three layers: scum, liquid waste, and sludge.

Here’s where microbes step in:

  • Anaerobic bacteria – working without oxygen, these bacteria target the sludge at the tank’s bottom. They transform up to half of the solid waste into gases like methane, hydrogen sulfide, and sulfur dioxide.
  • Aerobic bacteria – these microorganisms use oxygen to digest the waste, primarily breaking down the top scum layer.

Regular septic tank maintenance, including pumping out accumulated sludge, ensures that these microbial communities remain balanced and effective.

Microbes in the Drain Field are the Nature’s Quality Control

The middle part of the somewhat cleaned wastewater moves from the septic tank into the drain field, where it soaks into the nearby soil.

In addition to the treatment of wastewater in drain fields, there is another fascinating process that occurs – the formation of a biomat. This is a thick, tar-like bacterial slime layer created by anaerobic bacteria and other microorganisms in the surrounding soil.

The biomat adjusts itself based on the amount of biomass and wastewater, serving as an efficient filter for the effluent. It acts as a natural quality control system, slowing down the water’s flow and feeding on remaining nutrients, enhancing the cleaning process. The biomat also removes harmful biological entities like viruses and pathogenic bacteria through filtration and adsorption.

Filtration and Adsorption are Ensuring Water Purity

As the wastewater navigates through cracks, fissures, and pores in the soil and biomat, it undergoes filtration. This process traps particles and bacteria, further purifying the effluent.

Microbes adhere to soil particles, particularly capturing small viruses that could otherwise pass through the filtration system. Once immobilized, these pathogens eventually perish, contributing to overall water purification.

Maintaining Your Septic System

Maintaining your septic system properly is crucial for its health and efficiency. Regularly pumping the septic tank to remove accumulated sludge is essential. Maintaining an optimal balance of microbial populations within the tank is important to ensure proper functionality for a long time.

Your septic system relies on an intricate network of microbes and bacteria to function effectively. Understanding these microorganisms’ vital role and committing to regular maintenance ensures that your septic system remains in top working condition. Embracing the microbial world will benefit your property’s sanitation and contribute to a healthier environment.
