An underground storage facility for various liquids, such as gasoline, has a cylindrical storage tank within a substantially rectangular vault. The bottom wall of the vault is inclined downwardly, and any liquid leaking from the tank will run down the bottom wall and accumulate in the lower end of the vault. A vertical pipe is supported within the vault, such that the lower end of the pipe is raised just above the inclined bottom wall of the vault, and such that the upper end of the pipe extends through the vault and above the ground. A rod or other implement may then be inserted into the pipe to detect the accumulation of liquid in the lower end of the vault. The top wall of the vault has a removable manhole cover providing access to the interior of the vault for in situ repairs to the tank. The entire assembly is an integral fabricated structure that is lowered as a unit into the ground.

An underground facility for the storage of liquids, comprising a fabricated unitary structure adapted to be lowered into the ground as a unit and buried therein, the structure including a substantially rectangular, substantially totally enclosed vault having a top wall, a bottom wall, and four side walls therebetween, the side walls forming respective corners therebetween, a storage tank substantially disposed completely within the vault, the vault and tank having an access clearance therebetween sufficient to accommodate a repair person, spaced means supporting the storage tank within the vault, at least one substantially vertical pipe supported within the vault and disposed substantially adjacent to a respective corner thereof, the pipe having a lower end terminating above the bottom wall, the pipe further having an upper end extending through the top wall and above the ground, the pipe being sufficiently large to suitably accommodate a rod therein, thereby facilitating the detection of leaks from the storage tank into the vault, and the top wall having means therein providing access to the interior of the vault, whereby in situ repairs may be made to the tank, the bottom wall being inclined downwardly with respect to the top wall, wherein the vault has a lowermost portion at one end thereof for accumulation of leakage from the tank, wherein the pipe terminates just above the lowermost portion, and wherein the spaced means supporting the tank within the vault accommodates the relatively unimpeded flow of any leakage from the tank along the inclined bottom wall of the vault to the lowermost portion thereof.
