Wave ditch cover / Ditch Cover

Wave ditch cover

Flood is a natural disaster. If it happens in big city, the cost of damage will up to billion dollars. Although it is a natural phenomenon, sometimes human’s behavior often made the situation even worse. According to research, the main reason to result in flood is that human’s garbage obstructs the ditch. The bars of the ditch cover are shaped like a wave. When trash piles up on the ditch cover, the wave-shape bars prevent the garbage to block the ditch gate completely so that water can still flow down swiftly.
