Put a few drops of iodine in your toilet tank. If the iodine begins to appear in the toilet., you have a leak that may be wasting over 80 gallons of water each day. That's a lot!
2. Stop using your toilet to dispose of trash.
Every cigarette or kleenex you flush down also flushes away several gallons of water.
3. Use a plastic bottle in your toilet tank
Put some sand or pebbles in the bottom of a one gallon bottle to make it heavy. Fill the rest of the bottle with H2) and put it in your toilet, safely away from the flushing mechanism. In an typical home, the bottle may save six gallons or more of water every day without harming the efficiency of the toilet. If your tank is large enough, you may even be able to put in two bottles.
4. Take fast showers
A typical shower uses five to ten gallons of water a minute. Most Americans take way too long in the shower. Do the math!
5. Install water-saving shower devices
Your contractor or plumbing supply store stocks inexpensive shower heads or flow restrictors that will cut your shower flow to about three gallons a minute instead of six to ten. They are quite simple to install, and your showers will still be nice and refreshing.
6. Take a bath instead
A partially filled tub uses less water than all but the fastest showers. Pretty wild.
7. Turn off the water while brushing your teeth
The water wasted during brushing your teeth can really add up. Make it a point to use less!
8. Turn off the water while shaving
Much like brushing your teeth with the water running, shaving with the water on the entire time is a bad idea.
9. Check faucets and pipes for leaks
Small drips can add up.
10. Use your automatic dishwasher for full loads only
Better yet, air dry your dishes when possible.
11. Use your automatic washing machine only for full loads only
Your automatic washer uses 30 to 35 gallons per usage.
12. Don't let the faucet run while you clean vegetables
Use a bowl to clean veggies from the grocery store instead of running them under a stream of water.
