Water storage: Rainfall/tank size equation
In one book or another, I recall reading an equation that inputs the annual
rainfall and roof size in square feet (apologies to metric-based folks) and
outputs the # of gallons of water that can be reclaimed from said roof in a
year. I'm looking to determine the best size for a cistern for this
rainwater for our wet season/dry season climate in northern California.
If anyone has this equation a little closer to hand than I seem to, I'd
appreciate hearing it from you.
Thanks in advance,
The First Amendment went too far. It should have said, "Congress shall
make no law".
