A grease trap is a small underground tank positioned between your home’s drain line and the septic tank. It acts as a filtration system designed to seize grease, oil, and fat (also known as FOG) before entering the septic tank.

How a Grease Trap Works

Wastewater flows through your septic system’s grease trap, where cooler temperatures cause FOG to solidify and float to the trap’s surface. Meanwhile, the remaining wastewater, sans the FOG, flows through an outlet pipe and continues its gross journey to the septic tank for treatment.

Why Are Grease Traps Important for Septic Systems?

FOG can wreak havoc on your septic system in a few ways:

Clogged Drain Lines 

FOG buildup can do real damage by solidifying in your pipes, leading to slow drains and, eventually, complete blockages, resulting in backed-up toilets, bathtubs, sinks, and showers.

Overwhelmed Septic Tank Bacteria 

Your septic tank’s healthy (or good) bacteria break down waste. An inrush of FOG disrupts this balance, inhibiting the septic tank’s ability to function well.

Damaged Drainfield

A clogged septic tank can lead to untreated wastewater overflowing into the drainfield. This effluent can pollute the soil and groundwater and even cause the drainfield to fail.

The Importance of Regular Septic Service and Your Grease Trap

Like any filtration system, grease traps need regular cleaning to maintain effectiveness. A qualified septic service company can pump out the accumulated FOG, ensuring your grease trap continues to function correctly.

Here’s what a qualified septic service professional can do for your grease trap:


A septic service can assess the condition of your grease trap and identify any potential problems.

How Often Should You Have Your Grease Trap Serviced?

The pumping frequency depends on several factors, including the size of your grease trap, the amount of FOG produced in your household, and the size of your septic tank. An experienced septic service company can advise you on a recommended schedule for your specific situation.

In Conclusion

Installing and maintaining a grease trap is your investment in your septic system’s health.
