Turn It Off
It's a little thing that makes a big difference.
Sure, you need some water to get started, but we've all heard by now that you don't need to keep it running.
Shutting it off while you brushing your teeth & shaving can save up to 1,000 gallons of water a month.
Turn off the water while you brush your teeth.
Don't forget to sing "Happy Birthday" in your head. Twice.
Click the "I've Done This" button in the morning and again at night. Even during the day if your one of those people brushes your teeth at work.
They already know to turn the water off while they brush.
