Here are some of the best ways to save money on water, indoors and out:
Milk-jug your toilet: Fill a half-gallon plastic milk jug with water and affix the cap. Flush the toilet and place the jug in the tank, away from moving parts. This will save half a gallon per flush. Use pebbles or sand in the bottom of the jug if it doesn't stay put. Toilets use more water than anything else in a house, accounting for nearly 30 percent of indoor water use, according to the U.S. Environmental Protection Agency.
Think "on and off": Continuous flow uses more water than intermittent use. Turn the faucet on and off while brushing teeth, shaving, scrubbing kitchen pans and soaping the car.
