Home Water Survey

We must work together to preserve water. Water may be one of the most under appreciated natural resources we have because it is always there when we want it. However, water will be our next big concern after oil. Only approximately 5% of the water on earth is freshwater that can be used for drinking. That is why we seriously need to begin conserving our water supply. Conservation is easy. Remember this statistic: more than 70 % of indoor use occurs in the bathroom, and more than 20 % of it occurs in the kitchen and laundry room.

Activity / Normal Use / Conservation Use
Shower / 5 gal/min / 2 gal/min (low-flow device)
3-5 gallons (wet down, soap up,
rinse)
Tub Bath / 36 gal (full) / 18 gallons (half-full)
10-12 gallons (low level)
Toilet / 5-7 gal (normal) / 1.6 gallons (~3, regular with tank
displacement devices)
Brushing Teeth / 3 gal (running water) / 1/8 gal
(wet brush, rinse briefly)
Hand Washing / 5 gal (running water) / 1 gallon
(fill basin, rinse briefly)
Shaving / 3-5 gal (running water) / 1 gallon
(fill basin, rinse briefly)
Dishwashing by Hand / 20 gal (running water) / 5 gallons
(fill basin, rinse briefly)
Dishwasher / 15 gal/use / Use only when full
Washing Machine / 55 gal/use / Use only when full

Questions

1.  How does your daily water use compare to the average? Why do you think that there is a difference?

2.  Were you surprised by the results of this survey? After completing this survey do you think you will be more conscious about how you use water in the future?

3.  Can you think of some small changes that you personally can make to reduce the amount of water you use each day?

4.  The average person needs only 2.5 quarts of water a day to live a healthy life. Do you think that you would ever be able to reduce your water use to that number (there are 4 quarts in a gallon)? Why or why not?
