Notice: This is my first upload and it is work in progress. Please give me feerdback on what to improve or upload your improvements right away.
Origin/Idea: I have a 80 L water tank on my balcony to store water for my bonsai irrigation system. However, the rooftop where I collect the rainwater from is quite dirty after a dry period and the irrigation system gets clogged. This divice should collect some of the dirt in a pipe and close it afterwards. Then, the clean water is collected and the first flush water can drain slowly. For further understanding, please read this article:

THe two pipes where glued together with water resistant superglue. to ensure a nice closure of the top part of the pipe.
I also added a coarse filter for the initial collection into the pipes.
I have not tested the system thoroughly, so this is work in progress.
I also plan to integrate a fine-mesh filter after the bypass to further sort out dust before it is collected in the main tank.
