Toilet Running, originally uploaded by swimfast.

Take this opportunity to check to make sure that your toilet isn’t wasting water – the largest known cause of wasted freshwater in the U.S. Also, you should consider putting a brick or a filled 20 oz water bottle in your tank. You probably don’t need that water for flushing (try it out for a few days), and the added water savings add up quickly.
