"Snake wall"

Interesting installation to fix the inlet problem. I like the "snake style wall" to block the leafs while the rainwater flow into the inlet. If we can built the inlet point with a higher elevation than surrounding area and plant some plants to clean the rainwater, this interesting installation will not be used in this area. However, it is really interesting as a landscape element, and we should use it as a part of design in somewhere. Also, if it is possible, I will not use the plants to instead the "snake wall"( someone tell me the real name please), as a rainwater cleaner, it is really "easy clean" and "easy change".
