How A Septic Tank Works: A Brief & Complete Guide

Septic tanks are an important part of any home’s plumbing system, as they help to treat and dispose of wastewater. Knowing how septic tanks work is essential for homeowners who want to maintain the health and functionality of their septic systems.

In this blog post, we’ll explain the main components of a septic tank, how they work, and who should clean them for proper maintenance. All you need to know is here below. Let’s dive in!

The Main Components Of A Septic Tank

Three main components make up a septic tank: the inlet, the septic tank itself, and the outlet. Let’s talk about them.

  • The inlet is where wastewater from your home enters the septic tank. 
  • Inside the septic tank, the waste is broken down by a combination of bacteria and other microorganisms, which helps to remove harmful contaminants and prevent clogs or backups.
  • The septic tank outlet then releases treated water back into the environment, while any solid waste is collected and disposed of through the septic tank’s drain field.


If you want to ensure that your septic tank continues to function properly, it is important to perform regular maintenance tasks like cleaning the inlet, inspecting the septic system components, and checking for signs of clogs or other issues. 


How A Septic Tank Works

A septic tank is a large, underground tank that collects and contains waste from your home. It’s responsible for breaking down the waste and preventing it from entering the groundwater or local waterways. When wastewater enters a septic tank, it moves through several stages of treatment. 


  • The first stage is sedimentation, where heavier solids sink to the bottom as lighter solids stay on top. 
  • In the second stage, anaerobic bacteria break down organic matter at the bottom of the tank. This process produces gasses trapped by a floating scum layer on top of the wastewater. 
  • During the third stage, effluent (wastewater) emerges from the tank and flows into a drain field for further treatment and safe disposal.


Septic tanks are an important part of any modern wastewater system, requiring regular maintenance to keep them functioning properly. 


Professionals Should Pump Your Tank

To ensure they’re working properly, septic tanks need to be cleaned regularly by professional septic tank cleaners. DO NOT ATTEMPT TO PUMP IT YOURSELF, as you run the risk of getting sick from exposure to disease-causing bacteria. Here’s why.

Septic tanks are sealed containers that use anaerobic bacteria to break down black water and help remove contaminants like viruses and bacteria. Over time, these bacteria can deplete if they’re not properly replenished. This can lead to an imbalance in the tank and cause problems like poor waste treatment, sludge buildup, and even overflow if not caught in time.

This is why it’s so important to have your septic tank cleaned by a professional. Only experienced cleaners will know how to replenish the bacteria properly.
