In the example shown at left, our client is pointing to an area of obvious fill across the yard in front of his new home.

Everywhere else at this home site was thick with trees and also was swampy. The septic system tank and fields were almost certainly going to be in this (improperly prepared) mounded area.

Look in the distant photo at the original grade and you'll see that the contractor put the mound in a natural swale which turned out to be a natural creek - the system lacked sufficient fill soil - effluent moved from the leach field to the stream the contractor had buried, and simply appeared at the end of the mound. But that's another story.
