Question: What Is A Drain Field

How does a drain field work?

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.

The drainfield is a network of perforated pipes (or “laterals”) laid in gravel-filled trenches or beds.

Do leach fields smell?

Leach Field Odors The soil treatment area, or leach field, consists of an in-ground drain bed, field, or mound, and there should not be a strong septic odor unless there’s a problem. Have septic system pipes inspected to ensure there are no crushed or broken spots.

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.

How do you unclog a drain field?

Can you park on top of a septic field?

Parking or driving over a septic tank is never a good idea, but it’s even riskier in wet conditions. When the ground soaks up abundant moisture, a large amount of weight (like that of a vehicle) atop the movable soil can cause a shift in the ground.

How do you build a drain field?

How often does a septic tank need to be emptied?

Why does my septic tank fill up when it rains?

Septic systems are designed to only handle wastewater from the house. If runoff water from the storm gets into the septic tank, it will get full and since the soil in the leachfield will be already too saturated, the water will start backing up into the house or from the manhole.

Why doesn’t grass grow over my septic tank?

Lawn grass species prefer moist, high pH soil, and direct sunlight. Growing grass over a septic tank can be challenging due to the acidic, low-pH soil resulting from sewage runoff into the leach field.
