An underground secondary containment system (A) 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 (A) includes a double walled fuel storage tank (B) having isolated adjoining compartments (2, 4) for storing two different grades of fuel. A pair of dispenser sumps (C, E) are mounted on the fuel storage tank at opposite ends thereof. A pair of tank sumps (D, F) are mounted on the fuel storage tanks above the corresponding compartments. Each tank sump (D, F) is connected to each of the dispenser sumps (C, E) via flexible piping (12) which extends along the exterior of the fuel storage tank. In this manner, two different grades of gasoline can be provided to each dispenser (C, E) without utilizing piping disposed internally of the fuel storage tanks. The provision of separate tank sumps (D, F) which are not located below above ground dispenser units permits ready access to the pump (6, 16) and associated fittings.
L'invention porte sur un système de confinement souterrain secondaire (A) en grande partie préassemblé en usine avant son expédition sur le site d'installation. Ainsi, le temps passé à mettre en place le système de confinement sur le site d'installation peut être réduit. Ledit système de confinement (A) consiste en une citerne de stockage (B) de carburant à double paroi comportant deux compartiments (2, 4) contigus séparés pouvant recevoir deux types différents de carburants. Deux orifices de remplissage (C, E) sont placés aux extrémités opposées de la citerne. Deux regards de visite (D, F) sont placés au-dessus des compartiments correspondants. Chacun d'eux (D, F) est relié à son orifice de remplissage respectif (C,E) par une conduite souple (12) extérieure à la citerne. On peut ainsi fournir deux types différents de carburants à chacun des orifices de remplissage sans utiliser de conduites disposées à l'intérieur des citernes. La présence de regards séparés (D, F) non situés en position basse au dessus des distributeurs au sol permet un accès facile à la pompe (6, 16) et aux équipements associés.
