You can buy sections of a plastic pipe, about 3' in diameter and one to
three feet long. (At septic tank dealers) A lid fits on the top segment.
After you remove the concrete cover (permanently) run the plastic sections
to within 6" of the surface, put on the lid and cover it up with dirt or
flagstones, or whatever.

No more digging. Easy to find and pump the next time. Many owners have to
pump their tank every two years, or so. You can also check the level of
sewage and sediment quite easily.

I've got a standard resisdential septic system. It was installed 6 1/2
years ago, I live outisde of Colorado Springs. The diagram I have for the
system shows one holding tank, with a line going out to the leach field.

My question is, if I dig down to the lids on the holding tank, is it
possible to check the solids level to determine if I need the thing pumped
out?
