What is a Soil Drain Field?

A Soil Drainfield is one of the two main parts of a conventional septic system that you can find in a large portion of the country. The septic tank is the other dominant feature of private sewage systems. A Soil Drainfield functions as a Natural Waste Water Filtering System to remove impurities before septic tank liquids are distributed back into to the earth and groundwater below.

Septic Tank | Drainfield | Well Water

Most people have a basic understanding of what a Septic Tank is and what it does. However, if you ask anyone who has spent their lifetime paying for city water and sewer services about a Drainfield you may get a blank stare. Chances are pretty good that if you have Well Water that you also have a septic tank and drain-field located on the property.

 

5 Layers of Septic Soil Drainfield

The science of how a Septic Drain-field Works relies upon Chemical and Biological Processes as the effluent (septic tank liquids) percolate through the soil below the drainfield area. Soil that is a bit dry and contains lots of oxygen is much better than clay-type soil. Original soil that is permeable is best suited for several feet below the drain field surface. Layers of a typical Septic Drainfield:

  1. Ground Surface
  2. Backfill
  3. Perforated Pipe
  4. Washed Gravel
  5. Original Permeable Soil

 

How Does My Septic Drain-Field Work?

There is usually around 100 feet distance between a Well and a Septic Tank. The Soil Drainfield is even a further distance away because water that flows out of the septic tank then goes into the drainfield and filters through gravel filled trenches or beds. The wastewater is organically treated as it absorbs through the soil beneath the drain-field before it eventually makes it all the way down to the groundwater.
