Drain Field Restoration


Signs of Drain Field Failure

Most septic system problems begin with the drain field not working properly.

Common signs of a failed drain field are below:

Septic Odors

When beneficial bacteria colonies are flooded with drainage, they die and produce sulfites that have a bad odor. This is a sign that the bio-mat is no longer being kept in balance by the bacteria.

Slow or Backed Up Drains

When you notice drains in the house are draining slowly or backing up, that could be an early warning sign of drain field failure.


Puddles forming over the drain field or over the septic tank are a sign of total drain field failure. At this point, the ground is no longer accepting wastewater.

Water Returning to Tank

Pumpers observe wastewater in the drain field running back into the septic tank each time it’s emptied.


Causes of Drain Field Failure

Driving Over Drain Fields

Driving over drain pipes can cause them to break and stop working. Gravel filled drain fields will become compressed and limit their ability to absorb water.

Changes in User Habits

Grease and food put in drains or excessive levels of water can overwhelm the septic system. If more people have moved in or extra water is being used, then it may cause septic system problems.

Lack of Regular Pump Outs

Depending on usage, septic tanks must be pumped every 2 to 5 years. Without regular pumping, drain field failure will be caused by solids that should remain in the septic tank migrating to the drain field.

Plant Growth Near the Field

Roots from plants and trees can cause intrusion and damage to the drain field by clogging pipes.

Clay in Soil

The presence of clay in the soil means that an impenetrable layer of hardpan can form, limiting the drain fields’ ability to absorb water.

High Local Water Table

If you get a lot of rain or live near a lake, you may have a high water table in your area. Unless raised, the septic tank may be continuously flooded.

Fixing Drain Field Problems

Regular Pumps

Depending on your usage, schedule a pump for every 2-5 years to keep foodstuff and solid waste out of the septic drain field.

Softening Hardpan

Soil that has turned to hardpan can be restored by applying Septic Perc directly to the field (see application instructions).
For maintenance: Flush one-gallon of Septic Perc down a drain or toilet twice a year to prevent clay soil from turning in to hardpan.

Managing Bio-Mat

The bio-mat is a necessary feature of drain field. It allows wastewater to pass slowly through the soil while being processed. Excessive bio-mat growth stops drainage and can be prevented by applying Mega Bio directly to the drain field through a vent pipe or D-box.

Root Intrusions

Purchase a foaming root remover from a hardware or gardening store and get rid of roots blocking your drain pipes.
