Take a Navy shower
You may already be cutting back on showers or limiting the time you spend singing tunes under the steamy water, but there's another, even less luxurious way to conserve: the Navy shower. Invented by the Navy to save precious water rations, this showering technique uses just 11 gallons of water instead of the 60 gallons a typical shower requires.
Here's how to shower like a seaman: Turn the water on just long enough to get wet and then turn it off. Then soap up and don't turn the water back on until you're ready to rinse.
