Watch Rain Barrels Filling in Real-Time!

A single inch of rain falling on 1000 square feet of rooftop will generate 600 gallons of harvestable water! That’s enough to fill 11 standard sized rain barrels!

Watch for yourself to believe it! The 8-barrel (440 gallon) BlueBarrel System in the video will fill with less than 1.5″ of rain falling on the 450 square-foot rooftop area.
