SURFACE FOR CONTROLLING LIQUIDS

摘要

A liquid-controlling surface, comprising a formation comprising a plurality of individual cells for containing liquid, each of said cells having a cell wall; a plurality of distribution channels, one connecting each cell to each adjacent cell, each distribution channel being positioned on the internal cell wall at a height so as to channel liquid to the adjacent cell when a cell liquid level exceeds a predetermined limit; a perimeter wall for preventing liquid from leaking to an area outside the wall.
