Date Apr. 15, 1993A structure having at least one layer (3.1), for example three layers (3.1, 3.2, 3.3), of a number of juxtaposed sheet blocks, in which the sheets are shaped so as to define between themselves a series of vertical cells for water storage, and a series of horizontal cells in the height of the blocks for water drainage. The horizontal cells communicate with the vertical cells. The structure is light, inexpensive, easy to install without requiring heavy handling means, and is especially useful in underground water reservoirs.
