Approximately how many gallons of water are used per year in a typical home? 1 million gallons 500,000 gallons 150,000 gallons 1
Advocard [28]

146 gallons of water

<h2>Further explanation </h2>

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 <em>(father, mother, brother, sister). </em>

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 <em>(2 gallons)</em> = 73 <em>(gallon water refill frequency) </em>

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, <em>not for bathing, washing, pooping, urinating, etc. </em>
