A septic system is installed on property not serviced by municipal sewer lines. It features a tank that separates household waste into three layers: sludge, effluent, and scum. The remaining material, free of solid matter and oil, is then discharged to the drain field for final treatment. However, not all properties have enough room to support the standard model, in which case an aerobic system can be installed. Here’s how the two options differ.

What's the Difference Between Standard & Aerobic Septic Systems?

Standard Septic System

The septic tank is situated underground and connected to the home’s plumbing via an inlet pipe. Wastewater is discharged to the tank through this line, where it is broken down into a top scum layer and bottom sludge layer. The middle section of effluent is treated by anaerobic bacteria, and the liquid exits the tank through several perforated pipes. It is released into the drain field and surrounding soil. As the fluid trickles through the layers of earth, harmful coliform bacteria, viruses, and nutrients are removed before it is recirculated into the groundwater supply.

A standard septic system should ideally be placed on high, level ground to minimize the chances of flooding. Installers must also steer clear of sloped areas and any land that’s situated too close to bodies of water or obstructions—like power lines or tree roots.

Aerobic Septic System

The aerobic system is slightly more complicated since it depends on oxygen to treat the waste that enters a tank. After the materials are separated, the effluent is discharged to a neighboring aerobic tank, where it is exposed to an aerator that pushes air bubbles through it. The oxygen supports the system’s bacterial content, which is essential for efficiently and properly breaking down waste. The liquid is discharged to a pump tank, where it is treated with a disinfectant.

Often, an aerobic system is an ideal choice when there’s less room available for a larger conventional system. This option treats waste very quickly, making it an especially sensible choice for a sizable household.
