Showers usually use less water than baths. Install a water saving shower head that uses less than two and 1/2 gallons per minute and saves both water and energy.
If you take a tub bath, reduce the level of water in the tub from the level to which you customarily fill it.
Leaky faucets and faulty toilet fill-up mechanisms should be repaired as quickly as possible.
Check toilets for leaks that may not be apparent. Add a few drops of food coloring to the tank. Do not flush. If the color appears in the bowl within a few minutes, the toilet fill or ball-cock valve needs to be adjusted to prevent the water from overflowing the stand pipe or the flapper at the bottom of the toilet tank needs to replaced.
Reduce the amount of water used for flushing the toilet by installing one of the following: A new toilet (1.6 gallon); a toilet tank dam; or filling and capping one-quart plastic bottles with water (usually one is all that will fit in smaller toilet tanks) and lowering them into the tank of the existing 3.5 gallon or larger toilet. Do not use bricks since they may crumble and cause damage to the fixture.
Try to run the dishwasher with a full load, whenever possible.
Avoid running the water continuously for brushing teeth, washing hands, rinsing kitchen utensils or for cleaning vegetables.
Use faucet aerators that restrict flow to no more than 2.2 gallons per minute to reduce water consumption.
Keep a container of drinking water in the refrigerator instead of running the faucet until the water turns cool.
Insulate all hot water pipes to avoid long delays of wasted water while waiting for the heated water.
Ask your city, county, or local government about their programs to conserve water and how they can help you save water.
