Let's do the math. Conventional showerheads use 2.5 gallons per minute (gpm) of water. That means a 20-minute shower uses a whopping 50 gallons. No wonder showers account for 22% of the 340 billion gallons of water used in the US each day. The easiest way to cut back is to spend less time in the shower, but there are also inexpensive, easy-to-install devices that can make a big difference. Low-flow showerheads use half as much water (1 to 1.5 gpm) while faucet aerators mix air into the water stream. That way you can enjoy the pressure of a conventional showerhead while consuming less water. Make the switch today, and send less of this life-sustaining resource down the drain.
