ABSTRACT:
An enviromentally sound, non-contaminating underground liquid large storage tank leak containment, detection and alarm system containing: an impervious, steel reinforced, parallelpiped, non-fibrous concrete tank-containment vault. The vault has a fill pipe, a dispenser pipe, a vent pipe, and a vertical leak detection and pumpout pipe. Readily removable leak detection means are located near the vault floor within the leak detection and pumpout pipe. An electrical alarm is triggered by the leak detection means. The term "parallelpiped" describes the three dimensional vault configuration where the rectangular end walls and side walls, and the lid and floor portions are substantially parallel and each of the interior angles is approximately ninety degrees.
