Rain water storage

[grnspot110]

Good idea, thanks for the pictures. I see the 2 gutters empty to the pipe, that emptys into the three barrels. Does the end closest to the camera just 90 to the ground for anything to overfill out (if that makes sense )? I can't quite make out the smaller pipes on the bottom, I see how they collect from all 3 tanks. how do they empty? Thanks. Mark

2" pipe is overflow, 3/4" pipe at bottom goes underground to the greenhouse about 10' away, there it is hooked to a small pump. Up to the green garden hose behind the sprayer (2nd pic.).
