PROBLEM TO BE SOLVED: To provide liquid storage facility which allows for monitoring thickness of a liquid storage container by means of a simple method.SOLUTION: A metallic container 1 stores liquid, and a monitoring tube 2 is inserted into the liquid in a direction of depth thereof and has an internal space thereof partitioned from a space for accommodating the liquid. Measurement target sections (such as a wall surface of the monitoring tube 2) are arranged to be exposed to the space inside the container 1 and to be located at different positions along the depth direction, and comprise members made of the same metal as the container 1. The monitoring tube 2 is provided so that thickness of the measurement target sections are measured using a thickness measurement device inserted therein and the measurement results are used to monitor thickness of the container 1 at positions corresponding to measured positions in the depth direction. |
