Switch to an ultra low-flow showerhead. This could save you as much as 2.5 gallons every minute you shower. Take shorter showers—try to keep it under 5 minutes. Install ultra-low-flush toilets or place a plastic bottle filled with water or sand in your toilet tank to reduce the amount of water used in each flush. Put dye tablets or food coloring in your toilet tank and wait to see if the color appears in the bowl (without flushing). If it does, you have a leak! Check to assure that your toilet's flapper valve doesn’t stay open after flushing. When taking a bath, start filling the tub with the drain already plugged instead of waiting first for the water to get warm. Adjust the temperature as the tubs begins to fill. Turn the faucet off while you shave, brush your teeth and lather up your hands. Don’t use the toilet as a garbage can. Place a trash can next to the toilet and use it instead. Buy an electric razor or fill the sink with a little water to rinse your razor, instead of rinsing in running water. Take a short shower instead of a bath. While a five minute shower uses a 12 to 25 gallons, a full tub requires about 70 gallons.
