Properties without connection to a public sewage facility, rely on septic systems for wastewater treatment—either an anaerobic (standard) or aerobic system. Current and potential homeowners should know the merits and drawbacks of each. Here’s a brief comparison.

Standard vs. Aerobic Septic Systems

Anaerobic septic systems are deemed more traditional and conventional because they’re more commonly installed. In an anaerobic septic system, the bacteria inside the septic tank don’t require oxygen to thrive. Once wastewater settles inside, anaerobic microorganisms begin to break down solid wastes. Afterward, gray water moves into the drain field where it percolates through the soil.

On the other hand, an aerobic septic system makes use of separate compartments to treat wastewater. It relies on oxygen-loving aerobic bacteria to decompose waste faster and more efficiently. Since there’s little to no oxygen present, an air pump aerates the second tank to facilitate the consumption of waste by bacteria. The effluent then flows into the third compartment for another round of disinfectant treatment, resulting in cleaner water pushed into a smaller-sized drain field.

Choosing Between Them

Cost

In terms of overall costs, anaerobic septic systems are less expensive to install because of their inherent simplicity. They require only one septic tank to treat wastewater. Their aerobic counterparts need three tanks. One acts as a trash trap, and two are needed to thoroughly treat effluent. As a consequence, aerobic septic systems have higher upfront costs.

Available Space

Anaerobic septic systems, which allocate some treatment of wastewater to the drain field, require an expanse of unused, graded land. In contrast, aerobic systems require smaller plots for the drain fields because the water they expel is cleaner.

Soil Type

Not all types of soil are suitable as drain fields. Suitability depends on a soil’s capacity to absorb water. A percolation test will reveal if your soil drains moisture quickly and effectively. If it can filter water with ease, an anaerobic septic system may work in your favor.
