What would cause the grass above the septic tank to turn brown? Usually the grass is green above the septic tank, but for the past few days the grass have been turning brown and you can definitely see where the septic tank is and how big it is. Any ideas?

I believe you are right. It is not just above my septic tank that is turning brown. My whole yard is dying. My garden is dead and I guess the trees will be next. I thought we would get rain yesterday but it passed us by. We need a little moisture.

Could it be too much nitrogen and nutrients on top of all that extreme heat you are experiencing in the south?

During extreme dry conditions the grass will dry out faster over the tank, because there is less soil to hold the moisture.

:ditto: :ditto: only about 6 inches..
Really? Our septics here are much deeper than that. Our home is 22 years old and the tank is ~ 36" down. No wonder we don't get this condition even in the dog days of August. :)

Yup, it's definitely the depth issue; ours does the same thing in OHIO!! Oh, and it hasn't exactly been a dry year so far, but last time I looked, it was slightly brown over our tank. Oh, and yeah, we only have 6-9" of dirt covering the tank.

Depending upon the frost line and whether you have a basement, the tanks can be quite deep.

Now the hazard for us here in VA is that the collar going down to the tank will fill up with water during a heavy rain and can cause backflow problems in the basement.

Definitely the heat build-up from decomposing waste matter. If it's dry conditions the heat will evaporate any moisture in the ground and cause the grass to turn brown, especially if the tank is only 6-12" below grade like ours.
The grass doesn't die, just goes dormant & will come back once moisture is replaced.

This year hasn't been a problem yet, with all the rain we've had.

Bright side...in the winter time the snow also melts there first!!!:snowing:

If it is a gravity system the tank is set to catch a pitch to the leach field. Freezing the tank is not a problem if the tank is biodegrading the way it is supposed to. I live in the northeast and the tank at my flat farm is even with the ground and it has no issues.
