"I have a dual-flush toilet, which saves water by offering two flushing options: one that uses half the usual water, for easy-to-clean pee, and one full-strength, for situations we’d rather not discuss in public."

- Over a quarter of all the clean, drinkable water you use in your home is used to flush the toilets.
- Dual flush toilets save 5,126 gallons per year over a standard 3.5 gallon per flush (GPF) toilet.
- About 75 percent of the water we use in our homes is used in the bathroom. (California Energy Commission, 2006)
- Toilets from 1992 use between 3.5 to 7 gallons per flush. Newer, high-efficiency toilets use less than 1.3 gallons per flush — that's at least 60 percent less water per flush! (EPA, 2008)
