Choosing Between an Aerobic or Conventional Septic System

March 15, 2021 10:48 pm Published by Writing Staff

If you don’t have access to municipal sewer lines, you’ll need to install a septic system on your property. If you don’t have one, there is no way to safely dispose of waste. That is a health and safety hazard.

As you decide on the particulars of your septic system installation, one of the decisions you’ll need to make is whether you’ll invest in an aerobic or a conventional septic system. Both are effective ways to separate waste and treat your wastewater. The main difference is that aerobic systems use oxygen to achieve that goal, and conventional systems do not.

Here is an overview of the advantages and drawbacks to either system type.

Conventional septic systems

Conventional systems are also known as anaerobic septic systems, which simply means they do not use oxygen to process your wastewater. This is the most common type of system around the United States. There is very little oxygen present in the tanks. Instead, conventional systems use an underground tank. Solid waste sinks to the bottom of the tank, while the wastewater (effluent) rises to the top. A layer of scum is typically present at the top.

This type of system relies on anaerobic bacteria to break down both liquid and solid waste. The effluent is pushed out into a drain field, while the solids remain in the tank. These systems need to be pumped about once every three to five years, depending on how heavily they are used.

Aerobic septic systems

Aerobic septic systems are more complex. Instead of a tank and a drain field, these systems use a trash tank, treatment plant and pump tank to treat your wastewater. Both the liquid and solid waste enter the tank, where they separate into layers. Instead of immediately moving to the drain field, however, the waste percolates with the help of an aerator. Aerobic bacteria start breaking down both the liquid and solid waste.

After the waste is aerated, it’s pumped into the pump tank, where the water is treated using a disinfectant. The aeration helps keep the aerobic bacteria alive so they can break down the waste, which is faster and more effective than using a conventional septic system.

Which type of system should I choose?

There are certain advantages and drawbacks to both kinds of systems. Generally, aerobic systems require more maintenance, and the pump and aerator require electricity to operate. If you want to keep your costs down—and if your household is small—a conventional system may be best.

However, aerobic systems don’t require a large drain field, and they often come with an alarm to alert you to malfunctions. This is extremely helpful in preventing costly repairs or hazardous accidents. You’ll be able to fix the problem (or call your local septic contractor) far sooner than you might with a traditional septic system.
