Septic Tank Sludge Disposal

Septic Tank Sludge Disposal

Septic Tank Sludge Disposal


How do I get rid of "dry" septic tank sludge?

I recently dug out the sludge from an "out of use" septic tank. The sludge is the consistency of moist dirt. It is black, sticky and greasy. I have about 2 cu yds (800 pounds).

Can I use it as land fill and put it back in the soil? Do I need to dry it out first and then roto-till it in? I suspect the nutrients make it a good soil amendment, but the texture is so fine, I feel it would clog the soil.

There is enough here to choke a horse. <grin>


RE: Septic Tank Sludge Disposal

Will any local wastewater treatment authorities, septic tank pumpers, porti-potty renters take it off your hand?  That is the easiest solution.  Most of them are set up to handle sludge.

If not, check with your local DNR, EPA.  There are methods for land disposal of the sludge; but, the methods are determined by the nutrient value and metals levels of the sludge.  You don't have much to dispose of; but, you must still do it within regulations.
