It just so happens that I have data on our monthly water bills for the last 14 years; our utility reports in terms of cubic feet, so our average of ~11 cubic feet per day for a 4-person family is ~20 gallons per person per day, compared to the average of 83 gallons per person per day for California.
I will offer my usual complaint that while averages are informative, I would really like to see distributions of water usage by district. LA Times, show us some side-by-side boxplots so that we can see whether the average is due to a generally high usage in the population, or whether that average is pulled up by a few citizens with their own private Sea Worlds.
