Spot is downhill from the tank, gradual slope.

Just called the folks at the county (Wake County, NC 919 856-7400) and gave
them my address. They will research the property and let me know in 3-5 days
what they find on the original septic plan..

Thanks for the suggestion,
Robert

Interesting idea - 'big hole filled with rocks and sump pump'

My first reaction is to say no, definitely not a failed septic line. It
is
more than 100' from our septic tank, and on the other side of the house.
But, who knows?

100' from the tank is nothing when you consider the lines running from
the tank are several hundred feet long. Is this spot up or downhill
from the tank? If downhill, is there a big drop, or a gradual one? Any
chance you could find the original septic permit, from builder or
possibly county, to find where the drain field was supposed to be
located?
