Septic systems are an essential part of many homes and businesses, serving as an onsite wastewater treatment system. It is crucial that you understand how your septic system works to keep it in good working order and to avoid any costly repairs.

Components of a Septic System

1. Septic Tank

The septic tank is the primary component of a septic system. It is a large, underground tank that is typically made of concrete or fiberglass and is responsible for the initial treatment of wastewater. The septic tank provides a place for organic material in the wastewater to settle and decompose, while allowing the water to separate and move on to the second stage of treatment.

2. Drain Field

The drain field is a network of perforated pipes or chambers that are buried in an underground gravel bed or sand. The drain field allows the wastewater to be dispersed into the soil, where further treatment occurs by the soil’s natural bacteria.

3. Inlet and Outlet Pipes

Inlet and outlet pipes connect the septic tank and drain field to your home’s plumbing system. The inlet pipe connects to the toilets, sinks, and other fixtures in your home, directing wastewater to the septic tank, while the outlet pipe carries the treated wastewater from the septic tank to the drain field.

Functioning of a Septic System

1. Collection of Wastewater

The primary function of a septic system is to collect wastewater from your home or business and channel it to the septic tank. This could include waste from your toilets, showers, sinks, washing machines, and dishwashers.

2. Separation of Solid Waste

Once in the septic tank, the wastewater is separated into three layers: The first layer, known as the scum layer, contains solid materials that float on top of the wastewater, such as grease and oils. The second layer, known as the middle layer or effluent, is the liquid layer that is cleared of solids. The bottom layer contains the solid waste materials or sludge.

3. Treatment and Dispersal of Wastewater

As the wastewater enters the septic system, it undergoes a natural biochemical treatment process that involves the action of bacteria in the tank. This bacteria decomposes and helps break down the organic waste material in the wastewater before it is eventually released into the environment. Once the wastewater is treated, it is directed to the drain field for dispersal into the soil.

4. Maintenance of Your Septic System

To ensure that your septic system functions efficiently, regular maintenance is necessary. This entails having your system pumped every three to five years, depending on the size of your tank and the amount of wastewater produced. Regular maintenance also includes performing a septic inspection periodically. Your licensed septic professional will evaluate the state of your system by inspecting the components of your septic system and conducting a dye test. This test helps identify any problems in the system, such as clogs or leaks that need repair.


Proper functioning of your septic system is crucial for the overall health and well-being of your home and the environment. Understanding the components and functioning of your septic system can help you maintain it properly to prevent any untoward incidents. Adequate care of your septic system is not complicated, but requires some efforts. A good rule to follow is, never do anything that could harm or cause damage to your system. By following these tips and taking good care of your system, you can avoid costly repairs, protect your community’s water quality, and keep your family healthy and safe.
