A water table is a geological layer on a planet. Comprised of water, this layer was a key precondition to supporting life on Class M world. The ability to access and exploit the water table was a key part of the Federation's terraforming process.

One water table that was specifically known was that which was found on Velara III. It was a very thin ribbon between the sandy surface soil and harder rock layers below. (TNG: "Home Soil")
