Good stuff. We are moving to a small village in Panama and it blows my mind there that no one (I look) harvests rooftop rainwater there.

In the particular village we are relocating to the government turns on the water for 12 hours and then turns it off for 36 hours! So, here we are in an area that can get 200" of rain in a year and, if you have friends and family over, you can't even shower.

Currently we have a few of those blue barrels and an elevated 500-gallon tank but none of it is harvested from our rooftops. We just fill everything up during that 12-hour stretch. It's one of the first projects I plan to tackle when we move there permanently in 2017.
