Water Questions & Answers
How much water does the average person use at home per
day?
Estimates vary, but each person uses about
80-100 gallons of water per day. Are you
household
water is to flush the toilet, and after that, to
take showers and baths? That is why, in
these days of water conservation, we are starting to see
toilets and showers that use less water than before.
Many local governments now havg laws that specify that
water faucets, toilets, and showers only allow a certain
amount of water flow per rninute. Water agencies i n some
areas, such as here in Atlanta, Georgia, offer rebates if you install a water-efficient toilet. In
fact, I just put in two new toilets and received a rebate of $100 for each. Yes, they really do
use a lot less water, For your kitchen and bathroom faucets, if you look real close at the
head of a faucet, you might see something like "1.0 gpm", which means that the faucet
head will allow water to flow at a maximum of 1.0 gallons per minute.
NOTE: Our data here is very general in nature...just to give you a quick idea of your water
use. There are some other Web sites that will give you a much more detailed and accurate
estimate of your per-capita water use:
