Septic System Basics What Are the Different Types of Septic Systems?
All septic systems consist of two basic components: a septic tank and a drain field. The septic tank is where wastewater is housed and treated—solid matter and scum separate from wastewater liquid while anaerobic bacteria help to break down the biological waste. Treated wastewater, or effluent, travels from the tank to a drain field, where it can leach into the soil. A well-maintained system should last for over 20 years .

Conventional Septic Systems
As the name suggests, conventional septic systems are basic systems. There are two kinds of conventional systems: one that uses gravity as the way to move wastewater from the tank to the leaching field, and one that uses a pump to move water. Septic tanks in gravity systems are placed on a higher plane than the drain field, which helps water to flow into the tank and then to the drain field. In pressure distribution systems, a pump helps to distribute treated wastewater over the entire drain field, which is much more efficient.

Alternative Septic Systems
Alternative septic systems operate similarly to basic septic systems, only that they utilize additional methods to treat wastewater. For example, mound systems are needed in areas where the soil is too shallow or too dense, or where the water table is high. Leaching fields in these systems are raised above ground level like a mound, and a dosing chamber or pump chamber is employed to collect treated wastewater from the septic tank. It then pumps up and distributes the water to the raised drain field. Other alternative systems, such as aerobic treatment units, use oxygen in their septic tanks to expedite the break down of biological waste products. Sand filter systems are used in areas where the soil is limited.
