A double-walled, below-grade, modular, liquid containment vault that contains one or more primary storage tanks. Dispensing pumps and sundry conduits and support equipment are attached to or supported to a cover or top wall of the vault. The outer shell or base and primary tanks of the vaults can be constructed from concrete, steel, fiberglass or other composites. In concrete and steel vaults, the cover is secured to the primary tanks. The cover can also be bound to the walls of the outer shell. The pumps can be coupled to a remote control and communications kiosk. A manhole turret provides access to a ventilated secondary containment and inspection space within a base unit. Spill and overflow containment turret assemblies surround fill and vent pipes in the cover and direct spillage to the secondary storage space. Tertiary and auxiliary containment is also provided for spillage from the dispensing pumps and backup storage for the overflow containment assemblies. Additional standpipes communicate with the secondary containment and inspection space and support additional monitoring and inspection equipment.
