A method of making a storage tank system comprises forming a series of outer wall sections over a cylindrical-shaped inner storage tank. Each outer wall section is bonded to the inner tank at a distance of less than about 1/2 inch in height from the inner tank. The inner storage tank is strengthened by the wall sections. Partial secondary containment is provided by the outer wall sections. A monitored storage tank system with partial secondary containment is provided by the use of a leak detection system to monitor the closed spaces defined by the outer wall sections and the inner storage tank.
