If you have a septic tank, you may be aware of how biomat can build up in the drain field. Biomat is a bacteria that can form in the septic tank's drainfield, and if left unchecked, it will not allow the effluent from the septic tank to go into the drain field. The waste will eventually go back into the septic tank and then travel back into your home if nothing is done about this problem. Here is what you need to know about septic tank issues and how to repair them.

Drainfield Replacement

Replacing the drainfield should be the last resort when it comes to repairing your septic tank problems. It can become very costly to have done, which involves excavating your yard to dig out the drainfield and replace it with a brand new one. 

Hydro Jetting

A more practical solution to clear the drainfield is to use hydrojetting. This involves shooting a powerful stream of water into the header line to clear out everything that is inside the pipes. However, know that the process can be rough on your septic tank if it is not made with the right materials. If the system uses ceramic drain tiles or PVC pipes, hydro jetting can be rough enough to damage the pipes underground. 


Terralifting is a unique repair option that involves blowing air into the septic tank to break apart the biomat in the lines. Large equipment is placed in the yard on top of the drain field pipes. The equipment is capable of piercing the lines so that it can get the air into them from directly above rather than go through a cleanout. 

Chemical Treatment

You can try putting in a special chemical treatment solution directly into the septic tank's distribution box. The chemicals are designed to breakdown the biomat and get the waste flowing out of the tank once again. This is a potentially easy solution to dealing with biomat, so try this before you attempt any of the other solutions.
