A septic system is powered by bacteria—microorganisms that keep your septic tank working properly. Without them to break down the waste, the tank could clog or overflow. Use the following guide to learn more about these bacteria and how to keep them alive.

How Bacteria Work With a Septic System

Certain types of bacteria naturally occur in a septic system. They feed off of organic waste products, breaking them down into liquids and gasses.

There are two types of bacteria present in a tank: aerobic and anaerobic. Aerobic bacteria require oxygen and use solid waste as food. Anaerobic bacteria are smaller and don’t require oxygen. During bacteria digestion, solid waste is eaten, digested, and excreted by the anaerobic bacteria. This transforms the substances into gas and liquid form, where they are discharged through the drain field.

How to Protect a Tank’s Bacteria

If the bacteria in your septic system die, the tank will quickly fill with sludge, causing a plumbing emergency. Homeowners should engage in behaviors that protect the bacteria and help them thrive.

Avoid dumping harsh household cleaners down the drain, including bleach, drain cleaners, and disinfectants. While these substances kill harmful household bacteria, they’ll also kill the good bacteria in the septic tank. Other substances to avoid flushing or dumping down the drain include antibiotics, paint thinner, insecticides, and non-biodegradable detergents.

Avoid adding extra bacteria, enzymes, or activators to the septic tank. Since the bacteria in a tank occurs naturally, it’s unnecessary to introduce new bacteria into the mix. While it may seem like a good idea to add to the colony of bacteria, this can do more harm than good.

Have your septic tank inspected and pumped regularly to help the bacteria perform their jobs. Although bacteria do a great job of breaking down waste, a sludge still forms at the bottom of the tank, consisting of waste that can’t be digested. Get the tank pumped every three to five years. However, you may need more frequent pumpings if you use a lot of water or have a large family. Regular pumps and inspections ensure the effectiveness of the bacteria in a tank.
