How many gallons will a person drink in a leap year?

A person typically drinks about 2 to 3 liters of water per day, which is roughly 0.53 to 0.79 gallons. In a leap year, there are 366 days, so a person would drink approximately 193 to 289 gallons of water over the year, depending on their daily intake. This estimate can vary based on individual needs, activity level, and climate.
