Traditional Gravity System
The traditional gravity septic system is the most common type of septic system found in residential areas. This system relies on gravity to transport wastewater from the house to the septic tank and then to the drainfield. As wastewater flows from the house into the septic tank, solids settle to the bottom, and the liquid effluent flows out to the drainfield through a series of perforated pipes. The drainfield is a designated area in the yard where the wastewater is treated and eventually absorbed into the soil. This system works best in areas with plenty of space and well-drained soil.

Pressure Distribution System
In areas where the soil is not suitable for a traditional gravity septic system, a pressure distribution system may be installed. This type of system uses a pump to evenly distribute the effluent from the septic tank to the drainfield. The pump applies pressure to the effluent, allowing it to be distributed more evenly throughout the drainfield. This ensures that all areas of the drainfield receive an equal amount of wastewater, preventing any one area from becoming overloaded.
Mound System
A mound system is typically used when the soil conditions are not ideal for traditional gravity or pressure distribution systems. In this type of system, an additional layer of soil or sand is built up above the natural soil surface to create a mound. The septic tank is located below the mound, and the effluent is pumped up to the top of the mound, where it is distributed and treated before being absorbed into the natural soil. Mound systems are effective in sites with high water tables or shallow bedrock.
Aerobic Treatment Unit (ATU)
An aerobic treatment unit, or ATU, is a type of septic system that uses oxygen to enhance the treatment process. This system is designed to provide a higher level of treatment than traditional systems and is often used in environmentally sensitive areas or where space is limited. The ATU contains a chamber where bacteria break down and treat the wastewater. Oxygen is continuously supplied to the bacteria through an air pump or diffuser. The treated effluent is then disinfected before being discharged into the soil or a designated area.
Advanced Treatment System
An advanced treatment system, also known as a pretreatment system, is typically used in areas with strict water quality regulations or sites with limited soil absorption capacity. This type of system utilizes additional treatment steps, such as filtration, disinfection, or chemical processes, to further treat the wastewater before it is released into the environment. Advanced treatment systems are designed to remove a higher percentage of contaminants and ensure the effluent meets specific water quality standards.
Understanding the different types of septic systems is important for homeowners, contractors, and regulators involved in the installation and maintenance of septic systems. Each type of system has its own advantages and limitations, and the suitability of a particular system depends on various factors such as soil conditions, lot size, and local regulations. By considering these factors and working with qualified professionals, individuals can ensure the proper selection, design, and functioning of their septic system.
