A method of making a storage tank system comprises forming an inner containment wall comprised of a series of wall sections onto the interior walls of a cylindrical-shaped ribbed storage tank. Each wall section is bonded to the tank\s side walls at a distance of less than about four inches in height from the tank wall. Primary containment is provided by a tank formed of the wall sections and inner end caps. A monitored storage tank system with secondary containment is provided by the use of a leak detection means to monitor the space defined by the inner containment wall and the storage tank.
