ABSTRACT:
An above-ground liquid storage system (2) includes a steel inner container (4) encased within a layer (6) of reinforced concrete. The steel container has an upper opening (12) in an upper wall (10) thereof. An overfill reservoir (14) is positioned within the container below the upper opening so that the contents of the overfill reservoir are protected by virtue of being within, rather than outside of, the container. A fill pipe (18) extends through the overfill reservoir to permit user to introduce a liquid, such as gasoline or fuel, into the container. The fill pipe has an upper end (26) positioned above the upper opening and a lower end (22) positioned below the upper opening. An upper barrier (40), including a cylindrical wall (30) covered by a removable cover (34) to define an operating region (43) above the upper opening, is used to seal the upper opening. The overfill reservoir has a normally sealed drain (44); overfill liquid within the overfill reservoir is drained into the interior (16) of the container by the user opening a normally closed drain valve (46).
