ABSTRACT:
A draining well (2) extending downwardly from the bottom (3) of an underground cavity for storing liquefied gas under pressure has an upper portion (9) of large area and a lower portion (10) of smaller area. The volume of the upper portion is sufficient for filling a service tube (5) with water up to its hydrostatic equilibrium level. This enables the depth of the draining well to be reduced and thus makes such a storage facility cheaper to produce.
