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.
