How To Fix A Saturated Septic Leach Field
A septic leach field, or drain field is a critical component of a septic system. It allows wastewater from the septic tank to flow into the drain line and seep into the soil, where it is naturally cleaned and returned to the environment.
However, over time issues with leach beds can occur causing problems for the rest of your septic system. One of these issues is wet grass or pooling above your drain field. This can in turn lead to foul septic odors and slow draining in your home. In this article, we'll look at the most common causes of a saturated leach field and what you can do to fix it.
The Consequences of a Saturated Leach Field
A saturated leach field can lead to backups in your entire septic system. Additionally, it can pollute nearby water sources and harm the environment. In some cases, it can also cause a health hazard, as raw sewage can seep into the ground and contaminate your drinking water.

What Causes Water to Pool on a Leach Field?
What is a Biomat?
A biomat or biofilm is a layer of organic matter that forms on the bottom of a leach field bed and between the bed media. It acts as a barrier between the liquid wastewater and the soil creating a clogged leach field. Over time, the biomat can become too thick, making it difficult for water to pass through. This can cause the leach field to become saturated, which can result in wet grass, backups and foul odors.


Using Bacteria and Enzymes (biologic additives) to Fix a Saturated Leach Field
The most effective ways to fix a saturated leach field is to add additional bacteria and enzymes to the septic system. These biologic additive can break down the biomat and help to restore the flow of water through the leach field.
The anerobic bacteria will literally eat biomat turning it into water and CO2. That's right, you don't need to call a professional septic service company to dig up and replace your drain field, you just need to help it with organic waste digestion!

How to Use Bacteria and Enzymes to Fix a Saturated Leach Field

Wait for the bacteria and enzymes to do their work. This can take several days or weeks, depending on the size of the leach field and the extent of the saturation. Do not use chemicals like bleach or anti-microbial soap as this will negatively effect the helpful bacteria.
-
Check the leach field regularly to monitor its progress.
- Depending on the severity of the problem multiple doses may be required
