Reduce water use inside the home PDF Print E-mail

Every day people use water not only for drinking and cooking, but for bathing, cleaning and many other purposes. However, the amount used by families in their homes can vary because people have different water use habits and a variety of fixtures and appliances installed in their homes.
Water-using fixtures and appliances (such as faucets, toilets, showers, clothes washers, dishwashers) designed in the past two decades typically use less water than older devices, and water-using devices labeled as “ENERGY STAR” or “Water Sense” are the most water efficient.
The U.S. Environmental Protection Agency and the American Water Works Association collected water use data from over 1,000 homes in different North American cities. They found a wide range of water use rates, depending on whether or not families addressed leaks, how efficient the fixtures and appliances were in the home, and whether or not families applied conservation practices.
The largest amount of water use was from bathing, followed by the kitchen faucet and toilet. These were followed by the clothes washing machine, leaks, and other uses. The fixtures in this scenario were over 20 years old and had higher flow rates than newer more efficient fixtures. Leaks were most commonly due to the toilet, followed by faucets.
Alternatively, a family that fixed leaks and used the most efficient fixtures and appliances (meeting the Water Sense/ENERGY STAR standards) but maintained the same water use pattern (e.g., same frequency and length of appliance use) saw significant reductions.  
The total water consumption for a family of four under these conditions was about 176 gallons of water per day, which is less than half the water use as the first example. Further reductions in water use can be realized as the water use patterns are changed.
What can you do to be more water-efficient in your home?
• Identify and repair water leaks.
•  Change water use practices. Take shorter showers, flush the toilet less often, do fewer and fuller loads of laundry or dishes.
• Add aerators to faucets to reduce water flow while maintaining wetting ability.
• Replace older fixtures and appliances (especially toiles and washing machines) with more efficient, up-to-date versions.
Saving water in your home is important. Changing water use practices will cost nothing and may even save money as less water might be heated and used. Other conservation methods like taking care of leaks or adding an aerator to your faucet are fairly inexpensive. Water is a finite resource, and it is important that we work to conserve it, so it will be available for future use.
