ABSTRACT:
An underground secondary containment system that is preassembled to a large extent at a manufacturing site prior to shipping to the site of installation. In this manner, the time expended at the site of installation in installing the underground secondary containment system is reduced. The underground secondary containment system includes a double walled fuel storage tank having isolated adjoining compartments for storing two different grades of fuel. A pair of dispenser sumps are mounted on the fuel storage tank at opposite ends thereof. A pair of tank sumps are mounted on the fuel storage tanks above the corresponding compartments. Each tank sump is connected to each of the dispenser sumps via flexible piping which extends along the exterior of the fuel storage tank. In this manner, two different grades of gasoline can be provided to each dispenser without utilizing piping disposed internally of the fuel storage tanks. The provision of separate tank sumps which are not located below above ground dispenser units permits ready access to the pump and associated fittings.
