Abstract
Abstract Liquid containment apparatus comprising a metal storage tank mounted within a liquid impermeable, cast concrete vault. An open-topped, reinforced cast concrete vault base includes an internal thermal liner, liquid impermeable membrane, vault seal, tank cradles and support legs. Sloped interior walls, a sump and siphon facilitate liquid and/or condensate removal from the base. A vault cover is integrally cast with the tank and supports a number of projecting fill, vent, gauge, inspection, and siphon standpipes. Chamfered edges at the cover and lift hooks facilitate cover removal, alignment and tank inspection.
