The Task: Turn off the faucet while brushing your teeth.
Why It's Worth It: Brushing your teeth seems like a quick job, but before you know it, four gallons of water may have slipped down the sink.
Your One-Year Effect: 2,880 gallons of water saved.
The Effect If Everyone in the U.S. Did It for One Year: More than four times the Mississippi River’s annual flow of water.

The Task: Bring your water with you.
Why It's Worth It: Buying a daily bottle of water may quench your thirst, but it parches the planet. Each one-liter plastic bottle takes seven liters of water to produce. Refilling your own bottle directs the water where it’s needed — into your body.
Your One-Year Effect: 577 gallons of water saved.
The Effect If Everyone in the U.S. Did It for One Year: Equal to the amount of water that would cover Washington, D.C., by 52 feet.

The Task: Eat one more vegetarian meal a week.
Why It's Worth It: It takes a lot of water to grow the grain to feed the cow that ultimately produces a hamburger. Replacing just four ounces of beef in your diet a week with a vegetarian option can save more than 3,000 gallons of water.
Your One-Year Effect: 171,704 gallons of water saved.
The Effect If Everyone in the U.S. Did It for One Year: More than twice the volume of water in the Chesapeake Bay.
