Was your toilet made before 1993? Consider replacing it with a more efficient one.
A standard toilet uses nearly 4 gallons per flush (gpf) on average. By installing a 1.6 gpf toilet, a family of four will flush 14,000 fewer gallons per year. If a dual-flush toilet is installed, the savings can be more than 17,000 gallons of water annually.
If half of all U.S. households replaced one standard toilet with a dual-flush toilet, the water savings would total nearly 700 billion gallons per year.
This water savings is enough to fill the 6-million gallon Ocean Voyager Tank-the largest fish tank at the Georgia Aquarium, which is the largest aquarium in the world-once every 5 minutes, all year long.
