How much water faucets use | Regional Water Providers Consortium

Faucet

Switching to a WaterSense aerator or bathroom faucet will automatically mean that you will use 20% less water each time you turn on the faucet.

Installing an aerator - a small piece of hardware you screw on to the tip of your sink's faucet - can be one of the most cost-effective water conservation measures you can take. Aerators cost about a dollar, and in most cases, take less than a minute to install. Be sure to look for the WaterSense label when replacing your aerator or installing a new bathroom faucet. 

Many water providers give away low-flow aerators to their customers for free, or you can purchase one at most home improvement stores for less than $5. 

Waterwise Fact 

According to WaterSense, a faucet that leaks at the rate of one drip per second can waste more than 3,000 gallons per year.
