Win the Water War There are many options available for reducing your water use, and some even come with a financial reward. A tankless water heater, for instance, will allow you to heat up only the water that you need. When you buy an Energy Star-approved brand, such as Noritz (from $829), you'll get a $300 federal tax credit. A rebate plan might also be available from your municipal water district if you switch from a water-guzzling toilet or over-generous showerhead to a low-flow model. (Bricor sells water-saving showerheads for $75 and up; Caroma has a toilet that reduces water use by up to 67 percent; and Home Depot is now selling water-saving dual flush toilets.) You can also reduce water usage by shaving a few minutes off your shower time; design company Ripple Products is ready to help with an assortment of super-cute shower timers (from $3). But the easiest way to save the H2O? Turn off that faucet! According to the EPA, Americans can waste up to eight gallons of water each day brushing their teeth.
PORTABLE AND GOOD You might not have realized it, but millions of gallons of water (and oil) are used in the process of making plastic bottles, and two gallons of water are wasted in purifying every gallon of bottled water, not to mention the fact that most plastic bottles aren't being recycled. The perfect solution? The Wellness H2.O personal water bottle ($50, shown here), which purifies tap water while enhancing it with minerals—no disposable bottles needed!
