The drainfield is a shallow, covered, excavation made in unsaturated soil. Pretreated wastewater is discharged through piping onto porous surfaces that allow wastewater to filter though the soil. The soil accepts, treats, and disperses wastewater as it percolates through the soil, ultimately discharging to groundwater.

How do septic field lines work?

Why is my grass dying over my drain field?
As temperatures increase, grass draws more moisture from the soil beneath it. The soil above leach lines is shallower than the soil in the rest of the lawn, so it holds less water compared to the rest of the lawn, causing grass directly above the lines to dry out and turn yellow.
