How to Find Your Leach Field?

An introduction to locating leach fields

The piece of land where a septic tank drains all the wastewater before sending it back to the underground water table is called as a leach field or leach drain. It is also known as seepage field or drain field.

Uninterrupted functioning is vital for the efficient function of a leach field. It is very important to find or locate the location of your leach field since you must avoid landscaping, placing plants that are deep rooted or installing any other major building projects above or near the leach field. Luckily, there are various clues that may help you find your leach field. If the records of septic installers leach field repairs or building plans are inaccessible to you, then it may be very difficult to guess the location of the entire leach field.

If any kind of obstruction or tree root has not infiltrated or damaged the installation, then identifying the length of each distribution line would be viable. The uniqueness of each field may vary in regards to factors such as area size, land slope, location of well and obstacles such as rocks, buildings and trees.

Following Are Some Instructions For Finding Your Leach Field:

1) After following the drainpipe from your home to the septic tank, if you find that the tank and the drainpipe are underground, inspect them in the ground with a rebar rod. A rectangular raised region or depression, survey stakes, an electrical box or pipes can also identify a septic tank.

2) A downhill observation of the area shows that leach fields pull water downhill using gravity. By your observation from the septic tank, if the grass is greener or if the vegetation is intense, you have located the leach field. The ground may emit septic odors or can be soggy if the pipes buried in your leach field are broken.
3) Check out for a leach field on a day when the ground is covered with snow. The snow accumulated over a leach field melts faster as compared to the surrounding area.

4) In order to find the location of the leach field inspect the ground with a rebar rod and locate the leach field by following the septic tank’s end.

5) You can also contact your health department and enquire for your septic system’s record drawing. If the drawings are available, then you will see the location of the components of the septic system. In order to find the location of your drain field, measure the distance.

6) By examining your property’s outline, you may find clues for underground water such as furrows or depressions. Typically, the elevation of the drain field is lower than the septic tank and the house.

7) If you are unable to find the location of the leach drain on your own, then you can call a septic tank professional. He will help you find the metal pipes with the help of electronic detectors.


Henceforth, by utilizing any of the above given methods, one can easily find out the location of a leach field (or at least get close).
