8. Other indoor uses. Your family also uses water indoors in

How much water is used if each family member uses another
5 gallons per day?

9. Lawn watering. How many times a week does your family
water the lawn? About how many minutes do you water each
time?

This survey will tell you approximately
how much water your family uses daily.
1. Showers. How many showers does your family take in a
day? About how long is each shower?
X =
Number of showers Number of minutes Total shower time per day
2. Baths. How many baths does your family take in a day? A
half-full tub is about 18 gallons, a full tub about 36 gallons.
X =
Number in family Number of baths Total baths per day
3. Toilet flushes. How many times a day does your family
flush the toilet? (The average is four flushes per person.)
X =
Number in family Flushes per day Total flushes per day
4. Toothbrushing. Most family members brush their teeth
twice a day for about two minutes each time. Leaving the
faucet on while brushing wastes a lot of water. How often
does your family brush?

Column 1
Column 2 Column 3 Column 4
Now figure your family’s total water use.
Copy your answers from the previous page into column 3 below.
Where there is a choice, use the “High Flow” numbers in column 2 if your house has
older plumbing. If your house was built since 1994, or is retrofitted with low-flow
fixtures, use the “Low Flow” numbers in column 2.
Multiply column 2 b
y column 3. Put the answers in column 4.
This is the amount of water your family uses daily for each activity.
Next, add the numbers in column 4 to get an estimate of the total gallons of water
your family uses each day. Put the answer in the last line of column 4.

TOTAL family water use per day
Rainfall cycles vary, but even during rainy periods only a very small amount of rain
goes to replenish our underground water supplies. Dry periods, combined with a
higher demand for water
, can put a strain on our water supplies.
The av
erage adult needs only 2
1
/2 quarts of water a day to maintain health, but
each person in Florida uses about 120 to 150 gallons of water per day. And with
thousands of people moving to our state each month, future demand on
freshwater supplies will continue to increase.
That's why it's important to use water wisely (whether there's a drought or
not) in our homes, schools and businesses. By conserving water today, we
can do our part to keep water pure and plentiful for future generations.
By following a few simple steps, a family of four can save more than
30,000 gallons of water each year.
You can score big by following this water-saving game plan:
Stuff it. In the wastebasket, that is.
Toss tissues, insects or anything else you
want to get rid of in the trash, not in
the toilet. (Each time you flush, that's
several gallons down the drain.)
Limit your dribbling. Check for leaks or
drips in faucets and toilets. Don't leave
the water running while you brush your
teeth or wash the dishes. When washing
the car
, watering y
our lawn, or ev
en
bathing your dog, use a hose with a
nozzle that automatically s
huts off.
Make a clean sweep. Use a broom or
leaf blower
, not a hose, to clean y
our
driv
eway or sidewalk.
Be a team play
er
.
When helping with
chor
es ar
ound the hou
se, remember to
water lawns and gardens when it is
cooler outdoors — in the early morning
before 10 a.m., in the late afternoon
after 4 p.m. or at night. Water no more
than two days a week and only when it has
not rained. When doing dishes or washing
clothes, use only full loads in automatic
machines. Use one dishpan for washing and
one for rinsing when doing dishes by hand.
Take time out…to remind your friends and
family to con
serv
e.
Take water breaks, but don't let the tap
water run. Instead, keep a bottle of drinking
water in the r
efriger
ator
.
Don't linger in the locker room. Take
s
horter s
hower
s or fill y
our bathtub only
partly full.
Water conservation saves water, energy and money.
