One Less Flush
FACT: If everyone in the US flushed the toilet just one time less per day, we could save the equivalent of a lake full of water about one square mile and four feet deep every day, according to Green Living Ideas.
DIET PLAN: Flush less, repair leaky flappers, and retrofit the tank with water-conserving kits—or replace the toilet with one that carries the WaterSense seal (certified to use 1.28 gallons of water per flush).
