A double wall ribbed storage tank system is provided with the capability of independent monitoring of support rib areas and secondary containment areas of the tank system. The storage tank system comprises (a) an inner storage tank for primary containment of stored liquid with a set of support ribs for strengthening purposes, (b) an outer wall over the inner tank for secondary containment of the stored liquid, (c) rib communication means connecting together the support rib areas, (d) wall communication means connecting together secondary containment areas of the inner storage tank and outer wall, and (e) a monitoring station operably associated with the rib and wall communication means. Any structural damage to a support rib, inner storage tank wall or outer wall is detectable and generally located by the monitoring station.

A double wall ribbed storage tank system for independently monitoring support rib areas for leakage and secondary containment areas for leakage, said storage tank system comprising: (a) an inner storage tank having side walls and end walls to form an enclosed primary storage space for stored liquid

A double wall ribbed storage tank system for independently monitoring support rib areas for leakage and secondary containment areas for leakage, said storage tank system comprising: (a) an inner storage tank having side walls and end walls to form an enclosed primary storage space for stored liquid and further having a set of support ribs extending around the side walls at spaced intervals to create support rib areas encompassed by the support ribs and to add strength to said inner storage tank; (b) an outer wall extending over the inner storage tank to create secondary containment areas between adjacent support ribs and over the end walls for the stored liquid; (c) an independent rib fluid communication means which fluidally connects together the support rib areas; (d) an independent wall fluid communication means which fluidally connects together the secondary containment areas; and (e) a monitoring station operably associated with the independent rib fluid communication means and the independent wall fluid communication means to identify a structural failure in a support rib from a structural failure in the side wall or end walls of the inner storage tank or in the outer wall.
