SEPTIC SYSTEM OWNERS: WHAT YOU NEED TO KNOW ABOUT SEPTIC SYSTEM DRAIN FIELD FAILURE
The drain field receives septic tank effluent. It has a network of perforated pipes laid in gravel filled trenches or beds in the soil. Wastewater is distributed through the pipes to the gravel layer where filtering takes place before it enters the surrounding soil.
The soil below the drain field provides the final treatment and disposal of the septic tank effluent. After the effluent has passed into the soil, most of it percolates downward and outward, eventually entering the ground water.
There are different types and designs of septic systems and almost all of them rely on the ability of the soil to absorb water.
