If your property isn’t connected to a municipal sewer, then a septic system is necessary to ensure safe and efficient wastewater removal. But there are different varieties of systems. Standard and aerobic systems have noteworthy differences in how they operate, which can greatly influence which one is best suited for your needs. Here’s what you should know.

Standard Septic Systems

When most people think of getting a septic tank, they’re picturing a standard, or anaerobic, system. These options consist of an underground tank that collects solid and liquid waste.

The waste separates out into sludge and scum layers, which are gradually broken down by bacteria. Water typically remains in the tank for 24 hours before it passes through additional treatment tanks and is released into the drain field. 

Because of the long process to break down waste, a standard system could be overloaded and release contaminated water into the soil if it’s too small for the property’s water usage. However, these systems are generally reliable and are much less expensive than aerobic tanks.

Aerobic Systems

In an aerobic system, water goes through a trash trap before entering a compartment that introduces air into the tank. Because the bacteria and solid waste are kept in suspension by the airflow, the bacteria break down the waste faster. The bacteria settle out of the water when it reaches the calm compartment, then is sent back to the aeration area.

Thanks to their superior cleaning capabilities, aerobic systems are often used in areas where a standard system would struggle, such as properties with poor soil percolation or flat land.
