Baffled vs. Non-Baffled Septic Tanks

If you’re a septic system owner, you may have heard about baffles and their significance in your tank. Septic tank baffles play an important role in the functionality and longevity of your system. In this blog post, we’ll explore baffled vs. non-baffled septic tanks, understanding the purpose of baffles and why they matter in your septic system.

What is a Septic Tank Baffle?

First things first, what exactly is a septic tank baffle? A baffle is a wall inside the septic tank with a hole in the middle that naturally filters the floating scum and the settled solids within the tank. The wastewater comes into the tank through the inlet pipe, solids settle to the bottom, grease floats to the top, and the effluent, or grey water in the middle, flows through the wall to the outlet side of the tank.

How Does a Septic Baffle Work? 

The baffle is the first line of defense in your septic tank. Its role is to direct incoming wastewater downward and beneath the water’s surface. By doing so, it prevents the disturbance of settled solids within the tank. There are a few types of baffles, such as a wall baffle or a sanitary tee. A wall baffle extends below the water’s surface and helps stop solids from entering the drain field. Sanitary tees, on the other hand, redirect the wastewater downward without fully submerging it. This action protects the settled solids and pushes clarified effluent toward the outlet baffle.

The filter on the outlet pipe is called a “filter and housing,” sometimes known as a “baffle T-filter.” Situated at the opposite end of the tank, it serves as a barrier to ensure that only the clarified effluent leaves the tank. It prevents the solids from escaping into the drain field, preserving its integrity. The filter and housing also keeps floating scum from entering the outlet pipe. For this reason, it plays a significant role in maintaining the overall efficiency of your septic system.

Should my Septic Tank have a Baffle?

Now that you understand the importance of baffles, let’s discuss whether you need a baffled septic tank. In ACE’s opinion, the short answer is yes. Baffled septic tanks are the industry standard for a reason. Here’s why you need baffles:

  1. Effluent Quality: Baffles help ensure that only the clarified effluent leaves your septic tank, maintaining high water quality throughout the treatment process. Without baffles, there’s a higher risk of solids and scum entering the drain field, potentially clogging it.
  2. Extend System Lifespan: Properly functioning baffles protect your septic system, prolonging its life and preventing costly repairs or replacements. Without baffles, you’re more likely to experience issues that could lead to system failure.
  3. Prevent Drain Field Clogs: Baffled septic tanks efficiently retain solids within the tank. Without baffles, these solids can enter your drain field, clogging the pipes and causing failures.

Since septic tanks are manufactured with or without a baffle, they can’t be installed or removed without replacing the entire tank. For a healthy septic system, baffles are not optional. They are an integral part of a well-maintained septic system. If you’re concerned about your septic system’s baffles or suspect they might not function correctly, it’s important to seek professional assistance.
