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 and flanged edges at the cover and lift hooks facilitate cover removal and alignment, and tank inspection. The cover and tank are cast in alignment to one another at an elevated, multi-section molding form having sliding wing sections.
