|Future project: water catchment in rain barrels|
I bought most of my barrels off of CraigsList and have been trying to garner as many as possible, much like my little 20lb propane tanks (of which I have about eight).
The plan is to create a system much like LDSPrepper demonstrating in his YouTube video here. He incorporated a runoff tube that not only collects a majority of the sediment and debris but it can also be quickly drained via a threaded cap at the end.
I will probably use this system to water the garden but it certainly has more possibilities. I'm thinking about a configuration that consists of two columns, one on each side of the window. This will also be a good location to keep it hidden from view.
