Underground storage vault
First Claim
1. Liquid containment apparatus comprising:
- (a) a base having a plurality of sidewalls that project from a bottom wall to define an open cavity;
(b) tank means mounted within said open cavity for containing a liquid;
(c) means for defining secondary storage space between said tank means and the side and bottom walls of said base;
(d) an annular chase having raised sidewalls that border a through aperture that extends substantially the full length of said open cavity and that mounts to the sidewalls of said base, wherein said chase includes a plurality of pre-mounted conduits that couple to said tank means and wherein said chase includes an aperture through a sidewall and an elastomer seal cast into said sidewall and a fastener for securing said seal to a conduit having a bore aligned the aperture at the chase sidewall; and
(e) a plurality of cover that mount to said chase sidewalls to cover said open cavity.

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.
