146 gallons of water
Further explanation
The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people (father, mother, brother, sister).
If one person consumes 2 liters of water, then one house will consume about 8 liters a day.
Which will take up 2 gallons in 5 days.
1 Year = 365 days
365 days : 5 days (2 gallons) = 73 (gallon water refill frequency)
73 x 2 = 146
So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.
That is the calculation of the use of gallons for consumption, not for bathing, washing, pooping, urinating, etc.
