Abstract
The invention is a water remover-soil stabilizer, comprised of PVC pipes assembled in a polygonal shape with a discharge pipe at an upper end and connected to a water withdrawal pump. Water is admitted to the lower, horizontal pipe, through a plurality of extremely narrow slits, longitudinally spaced, and laterally extending circumferentially therein which render the section water pervious. After the pit is dug, the invention is inserted into the pit and the pumping is started. The invention withdraws only the water since the width of the slits is less than the diameter of the average sized sugar-sand grain.
