DIY Rainwater Diverter


One of the most important parts that you need when building a rainwater catchment system for your home is a first flush diverter. The device simply allows the initial rainwater runoff from the roof to bypass your catchment barrels; preventing bird droppings, dust and other contaminants from entering your system.

There are commercial units on the market but I prefer to try and save some money with a DIY version. I have seen some designs over the years for a rainwater diverter that made me feel like I needed a PHD to figure them out, but the video above made me feel the exact opposite. It’s so simple that I felt dumb for not even thinking of it; I’m definitely replacing our current diverter setups this spring with this method.

For further information on rainwater collection the Texas Water Development Board put together an excellent rainwater collection manual as seen below.
