An average American family uses more than 300 gallons of water daily—70 percent of which occurs indoors. The largest use of household water is to flush the toilet, followed by taking showers and baths. Toilets account for nearly 30 percent of an average home’s indoor water consumption.
Older, inefficient toilets can use as much as three to six gallons per flush. Your household can help curb water use by fixing toilet leaks and/or purchasing a new water-efficient toilet, most of which use 1.28 to 1.6 gallons per flush. WaterSense-labeled models can reduce water used for toilets by 20 to 60 percent, which can save nearly 13,000 gallons of water and $110 every year for the average family.
