Cut your shower time in half from 10 to 5 minutes and you’ll save more than 4,200 gallons of water a year and lower your utility bill too! Now another idea is to take a “Navy” shower. Get in get wet turn the water off while you wash then rinse off. This alone can save a bunch of water. Switching out your shower head to a low flow model can conserve water and you may be surprised on how well they work.
