Abstract
A below-grade, modular cast concrete containment vault which contains one or more primary liquid storage tanks. Dispensing pumps and sundry conduits and support equipment are attached to or supported within a cast concrete base cover or a conduit and equipment chase and chase covers. The base cover or chase is supported on the vault base. The pumps can be coupled to a remote control and communications kiosk. A manhole permits access to a ventilated secondary containment and inspection space within a vault base. A remote fill base and a sealed conduit contain liquid and vent piping and couple to the chase. Spill and overflow containment assemblies surround fill and vent pipes in the vault base cover, chase cover and remote base and direct spillage to the secondary storage space. Tertiary and auxiliary containment is also provided for containing leakage and spillage and backup storage for the overflow containment assemblies.
