In other
words, when I have a big storm over my house, just how much
rain am I getting? Let's say your house sits on a one-half
acre lot. And let's say you get a storm that drops 1 inch of
rain. You've just received 13,577 gallons of water on your
yard! A big bath holds about 50 gallons of water, so if you
could save that inch of water that fell you could take a
daily bath for 271 days! (Careful now, that 13,577 gallons
of water weighs over 56 tons ... so don't put it in your
bathtub all at once).
Let's expand that to a city.
Atlanta, Ga. had corporate boundaries
that cover about 87,000 acres (1988). A 1-inch rainstorm
deposits 27,152 gallons on one acre, so during this storm
Atlanta receives 2.36 billion gallons of water.

guess how much water falls during a rainstorm. |
