So about 10.5 inches of rain would be needed to attain the full 13,000 gallon capacity. Minus the water that is used between rainstorms.

Would be interesting to see how effective this system is in parched areas of the country.

Yeah, like where I live in the Great Basin Desert, where if we get 5 inches of rain in a normal year we are blessed.
