 Does Your Septic System Use Electricity? Understanding the Power Behind Wastewater Treatment


When it comes to septic systems, many homeowners wonder about the role of electricity. Does your septic system use electricity, and if so, how does it impact its operation?

In this blog post, we’ll delve into the world of septic systems and shed light on the use of electricity in wastewater treatment.

Understanding Septic Systems:

Septic systems are a common wastewater treatment solution for homes that are not connected to municipal sewage systems. They consist of a septic tank and a drain field, working together to treat and dispose of household wastewater.

Electricity in Septic Systems:

Whether or not a septic system uses electricity depends on its type and design. Let’s explore the two main categories of septic systems and their electricity usage:

1. Conventional Gravity Septic Systems:

These systems rely solely on gravity to move wastewater from your home into the septic tank and then into the drain field. Since they don’t have mechanical components like pumps, they do not use electricity. Gravity does the job naturally, allowing wastewater to flow downhill.

2. Aerobic Septic Systems:

Aerobic septic systems are more advanced and efficient than conventional systems. They use oxygen to break down and treat wastewater more effectively. In these systems, electricity comes into play as they incorporate aerators or air blowers. These devices introduce oxygen into the septic tank, promoting the growth of aerobic bacteria that accelerate the treatment process. Therefore, aerobic systems do use electricity, primarily for aerator operation.

The Role of Electricity:

So, what does electricity do in an aerobic septic system? It serves several crucial purposes:

  • Aeration: The aerator or air blower injects oxygen into the septic tank. This oxygenation creates an environment where aerobic bacteria can thrive, enhancing the breakdown of organic matter and contaminants in the wastewater.
  • Effluent Pumping: In some cases, septic systems may include effluent pumps to move treated wastewater from the septic tank to the drain field. These pumps rely on electricity to function.

Benefits of Aerobic Systems:

While aerobic septic systems use electricity, they offer advantages such as:

  • Enhanced Treatment: Aerobic bacteria are more efficient at breaking down waste, resulting in cleaner effluent.
  • Smaller Drain Field: Due to improved treatment, aerobic systems often require a smaller drain field, making them suitable for properties with limited space.
  • Reduced Odor: The oxygen-rich environment in aerobic systems helps reduce unpleasant odors associated with septic tanks.


In summary, whether your septic system uses electricity depends on its type. Conventional gravity systems do not use electricity, relying on natural gravity flow.

On the other hand, aerobic systems use electricity to operate aerators and, in some cases, effluent pumps. While electricity is a factor in these systems, it contributes to more efficient wastewater treatment and reduced environmental impact.

Understanding the role of electricity in your septic system can help you make informed decisions about maintenance and potential upgrades.

It’s essential to consult with a professional to ensure your septic system functions optimally and complies with local regulations.

So, to answer the question, “Does your septic system use electricity?”—it depends on the type of system you have.
