That's what I was thinking, sand, but I had no sand on hand this

A few years back, I found another similar hole but smaller. *id the
same thing, filled it with bolders and I haven' seen any errosion.

I'm not sure why that other hole was there. Does a typical septic
system have two chambers spread appart?

This past weekend I filled the hole with rocks and bolders.

Really, really bad idea. Before going further, get a load of sand
(that's SAND!) and start filling it. Bank run gravel may settle
eventually, but sand will compact between the rocks many times faster.
Keep it a foot below grade until next summer, then do the topsoil and
grass seed routine.

*hat you did was fine. *Excellent in fact.
ust put 6 inches of
topsoil and grass sod over your 6 inch deep depression for now and
then add sand or topsoil as it continues to settle over the next few
years.

You know our land is continually moving and corrections have to be
made even in those places where there was no hole. *Telephone poles
and fences show leaning posts after just a very few years and animals

big boulders bad, as the dirt he planned putting on top filters down
it migrates into the old leach field, and requires continiuos
replacement.

lots of old septic tanks were reused as a leach field for downspout
drains. hopefully thats not the case here.

abandoned and forgotten septic tanks and pits left over from sewer
disposal are pretty common.

these were abandoned long before laws were enacted on proper disposal.

my best friend uses his old tank for downspout water disposal. I saw
in the tank recently his dad filled it with garbage when it was taken
out of service over 50 years ago. he dug it up to check the lid, which
was still in remarkably good condition for its over 100 year age.

my buddy was concerned the lid might be rotting.

truckload of sand way cheaper than bags- Hide quoted text -

Your wrong

My home was built on farmland in 1950/ A hand dug well was in my back
yard and filled with rock and boulders at that time 1950. a neighbor
watched it being filled in.......

I moved here in 1972 and it was still the neighborhood dirt dump site
and continued to be till the 1990s. I added many truckloads of dirt to
finally stabilize it.

The water tends to carry the fill away. Note the OP tank had water in
it draining no doubt to the original field.

Just dump dirt boulders in there and it will endlessely sink
