ABSTRACT:
Tank secondary containment system, principally for underground fluid storage tanks such as for fuel storage, which is applicable to both single wall tanks and double wall tanks for providing secondary, double wall fluid containment in the regions of access pipe fittings and pipe connections, which are the places most prone to failure. For double wall tanks, the invention completes the secondary containment which is conventionally only partially afforded by double wall tank construction. Access fittings at the top of the tank and at least lower portions of their respective function pipes which extend to surface equipment are surrounded by tubular secondary containment covering, the lower portion of which is preferably a riser, which is bonded and sealed to the outside of the tank for either a single or double wall tank, and for a double wall tank may extend through an aperture in the outer wall down to the inner wall. If desired, the secondary containment covering may extend coextensively with the function piping to surface equipment.
