In this article, we will delve deeper into the inner workings of a septic system, exploring each component and its role in the overall treatment process.

What Is A Septic System?

A septic system is an on-site wastewater treatment system that is commonly used in areas where properties are not connected to a municipal sewer system. It consists of several components, including a drain line, septic tank, drainfield, and distribution box, that work together to collect, treat, and dispose of wastewater.

What Are The Components Of A Septic System?

  • Drain Line

A drain line is a pipe or series of pipes that carry wastewater from various sources, such as sinks, toilets, and showers, to a septic tank.

  • Septic Tank

A septic tank is a large, watertight container typically made of concrete, fiberglass, or plastic that collects all the wastewater from your home. The tank separates solids and oils from the water and allows them to settle at the bottom of the tank while allowing the liquid to flow out into the drainfield.

  • How Does A Septic Tank Work?

A septic tank may seem complicated, but the way it works is actually quite simple. Here is the step-by-step process of how a septic tank works:

  • Wastewater collection: All wastewater from your home flows into the septic tank through the inlet pipe.
  • Separation: Once inside the tank, the wastewater separates into three layers—scum, effluent, and sludge.
  • Treatment: The effluent undergoes further treatment inside the septic tank. As the wastewater passes through the tank, naturally occurring bacteria and other microorganisms in the tank break down and digest the organic matter in the wastewater.
  • Effluent discharge: The partially treated wastewater exits the septic tank through the outlet pipe and flows into the drainfield.
  • Sludge and Scum Removal: Over time, the sludge and scum layers in the septic tank will gradually build up, and they will need to be pumped out.


Also known as a leach field, this is where the wastewater from the septic tank goes to be filtered and treated further. A drainfield is typically made up of a series of perforated pipes or chambers buried in gravel-filled trenches in the soil. The pipes allow the wastewater to be distributed evenly over a large area of soil. The wastewater is further filtered and treated by naturally occurring bacteria and other microorganisms in the soil.

Distribution Box

This is a small box that connects the septic tank to the drainfield pipes and helps to regulate the flow of wastewater. The distribution box evenly distributes the wastewater from the septic tank to the drainfield.
