Not the same thing. A "French Drain" or a "Drywell" is a hole into which water
goes to percolate into the soil.
A sandrock sewer is an actual sewer. Sanitary sandrocks here carry effluent
which eventually winds up at the Pig's Eye sewage treatment plant. Storm
sandrocks carry rainwater which ends up in the Mississippi River. We used to
have combined sewers here, but a Federal Court Order caused us to separate the
entire system a few decades ago.
