ABSTRACT:
An overflow containment system for metal or fiberglass liquid storage tanks mounted within a liquid impermeable, secondary storage space. An open-topped, reinforced cast concrete base includes an internal thermal liner, liquid impermeable membrane, vault seal, tank cradles and support legs which define secondary and tertiary containment spaces. Sloped interior walls direct liquid and/or condensation to a sump region and a siphon assembly. A vault cover is bonded to the tank and supports a number of projecting fill, vent, extraction, inspection, and monitor/siphon standpipes. Chamfered and flanged edges at the cover and lift hooks facilitate cover removal, alignment, and tank inspection. A spill containment collar is mounted about the fill pipe and a drain pipe directs spillage to the secondary storage space of the base.
