At its most basic level, septic installation requires choosing between two types of bacteria. Anaerobic bacteria breaks down waste in conventional or standard septic systems while aerobic bacteria does the same job in a system of the same name. Here, learn about the differences between the systems to determine what’s right for your property.

Standard Septic Systems

This septic system features a tank, perforated pipes, and adjoining drain field. The tank collects all household plumbing waste for separation, with solid waste sinking to the bottom to slowly break down via anaerobic bacteria. Grease, fat, and any other floatable matter rise to the top of the tank. Wastewater vacates the tank through the perforated pipes and into the drainfield where it naturally filters through the soil before reaching groundwater.

A standard or anaerobic system is right for your property if you have the space for a drain field and the landscape slopes slightly to promote efficient wastewater drainage. You must also have “percolating” soil, as clay and other compact soils do not absorb and clean wastewater efficiently. Standard systems are also cheaper because they don’t require as much labor to install.

Aerobic Septic Systems

An aerobic system relies on three tanks to deal with liquid and solid waste. All waste enters the first tank from household plumbing where it settles into layers like the traditional version. However, wastewater in aerobic systems gets moved to a second tank that circulates air bubbles to keep aerobic bacteria active. This bacteria cleans wastewater quickly before it’s sent to a pump tank for one final cleansing. The water is then dispersed through property sprinkler heads.

Since aerobic septic installations do not require drainfields, sloping landscapes, or non-compact soil, they are ideal for smaller, flatter properties. This system costs more than standard versions due to its complexity; however, it reduces monthly utility bills by providing lawns and gardens with recycled water. It also includes an alarm that alerts you to any issues. Standard systems provide warning signs through sewage odors, plumbing backups, and soggy drainfields; however, routine septic tank cleaning easily prevents these issues.
