If you’re a homeowner who’s never had a septic system before, you may be curious about how they work. While the tank and pipes are the most commonly known parts, the leach field, or septic drain field, is also an integral component of the setup. 

A Guide to Septic Leach Fields

How Does a Septic System Work?

It’s important to understand the system as a whole to understand how the leach field works. When waste goes down your home’s drain, it ends up in your septic tank, where it’s naturally separated by weight. Food particles and other solids end up on the bottom of the tank, while fats, oils, and greases float to the top. In the middle is a layer of wastewater, known as effluent.

What Is the Role of a Leach Field?

As the tank's levels rise, the effluent leaves the system, exiting into the drain field. This field comprises a sizable area where several pipes run into a bed of gravel. The pipes are full of small holes, allowing the effluent to escape and disperse evenly throughout the gravel.

After the effluent filters through the aggregate layer and into the soil, bacteria will feed on and get rid of the remaining organic matter and pathogens in the wastewater.

What Are the Common Signs of Drain Failure?

If a leach field is failing, you may notice water pooling on your lawn or grass becoming discolored. If a tank is not pumped regularly, sludge can build up and clog the drain pipes, keeping effluent from being able to escape. If you notice water pooling on your lawn, or the grass becomes discolored, your tank may need to be pumped to reduce sludge levels.
