Abstract
A double walled storage tank includes an outer wall, an inner wall, a plurality of ribs disposed between the inner and outer walls, and a plurality of annular spaces between the ribs. The annular space between each pair of ribs is connected to other annular spaces only at the top of the tank. When a leak occurs in either the outer or inner wall, the annular space corresponding to the leak will at least partially drain while the other annular spaces will remain full. Thus, the leak location can be determined by simply examining the annular spaces between pairs of ribs.
