ABSTRACT:
A method of making a storage tank comprises forming a cylindrical-shaped inner tank with integral support ribs and forming an outer wall comprised of a series of sections which are at least partially separated from the inner tank's walls between each set of support ribs. Each outer wall section is bonded to side walls of adjoining ribs at a distance of less than about 90% of the height of the support ribs such that the ribs protrude from the outer surface of the storage tank system. The inner and outer walls of the system are both strengthened by the common support ribs. Secondary containment is provided by the outer wall. A monitored storage tank system is provided by the use of a leak detection means to monitor the closed space defined by the rib interiors, the outer wall and the storage tank.
