Check your faucets, toilets and pipes for leaks. To check your toilets for leaks, put a little food coloring in your toilet tank, if the color begins to appear in the bowl within 30 minutes, you have a leak. Small drips can waste a significant amount of water with 20 gallons of water per days and larger leaks can waste hundreds of gallons.

Don’t use the toilet to dispose of your cigarette butt, facial tissue or any other bits of trash.
Check your house water meter before and after two hours when you no water is used. If it doesn’t read exactly the same, there may be a leak.

Use and install water-saving shower heads and low-flow faucet aerators. Low-flow means that it uses less than 2.5 gallons per minute of water for your faucet aerators.
Put plastic bottles with an inch or so of pebbles or sand and put it in your toilet bank.
Be sure that there is at least 3 gallons of water remaining in your tank bank of your toilet. The more times your try to flush on your toilet, more water is wasted. It is suggested that you should buy an adjustable toilet flapper setting that helps you have a single good flush every time.

Insulate water pipes by pre-slit foam pipe insulation. It will get your hot water faster with lesser water wasted.
Don’t take too long in the showers. This is the oldest advice in saving water. Turning off the shower when you shower then turning it on again to rinse would help decrease wasted water when you shower. Remember, even a fast four-minute shower uses an estimate of 20 to 0 gallons of water.
Turn off the water when you are brushing your teeth.

Use dishwasher and clothes washer for only full loads. Pre-rinsing dishes is not usually recommended by dishwashing manufacturers. With washing clothes, avoid the permanent press cycle. If you want to buy new clothes washer, consider buying a water-saving frontload washer.
Minimize use of the kitchen sink garbage disposal units and instead, just start using a composite pile as a alternate method of disposing your food wastes.
Don’t let the faucet run while you clean the vegetables. Rinse them in a stopped sink or a pan of clean water. Or you can always use a dual-setting aerator.

Keep a bottle of drinking water in the fridge. Running for tap water is wasteful. Consider storing drinking water inside your refrigerator in a clean safe-drinking bottles in order to enjoy a cold and refreshing drink.
Don’t water the gutter.
Put a layer of mulch around your plants and trees. Adding two to four inches of organic material such as compost or bark mulch increases the ability of the soil to retain moisture thus not requiring you to water your plants as much especially during the summer season.
