Septic systems come in two varieties, standard and aerobic. Although both systems accomplish the same goal—the breakdown of sewage and effluent treatment—each achieves this objective through different means. When installing a new septic tank on your property, understanding their differences as well as their advantages and disadvantages will help you more effectively collaborate with your contractor. Here’s what you should know about standard and aerobic septic tanks.

Standard Septic Systems

In a standard septic system, waste enters the septic tank and settles at the bottom. Liquid waste floats to the top. Anaerobic microbes, which are active in the absence of oxygen, break down both liquid and solid waste, producing wastewater effluent that then passes through the treatment tank before it’s deposited in the drain field that surrounds your tank.  

Aerobic Septic Systems

Aerobic septic systems have three compartments: a trash tank, a treatment plant, and a pump tank. Like standard septic systems, solid and liquid waste enter the trash tank and settle in layers. Wastewater then travels to the treatment plant, where an aerator circulates the liquid to create oxygen bubbles that speed breakdown. Aerobic bacteria decompose waste more quickly than anaerobic microbes.

Septic System Comparison

Because standard septic systems are simpler in construction, they’re often less expensive to install. Conventional tanks typically have alarms that alert owners to potential system malfunctions, helping them avoid costly repairs.

Although more expensive, aerobic systems often release cleaner water and require a smaller drain field. They’re a smart choice for those with less space. In some cases, impermeable soil, or soil that does not allow water to percolate efficiently through to groundwater reservoirs, necessitates the installation of an aerobic septic system.
