Showering is a significant use of water in American homes. On average, individuals typically take 8-10 minute showers every day, using about 17 gallons of water each time.
If everyone in the city of Flagstaff with its current population took showers like that - 365 days a year - it would add up to almost 460 million gallons of water annually; an amount equivalent to about 10% of the water in Lake Mary when it’s filled to the brim.
