Toilets account for 27% of every US citizen’s indoor water use. If every appliance in the US was a water-efficient model, the country would save a whopping 3 trillion (yes, trillion with a “T”) gallons of water every year. That’s enough water to fill 75 billion bathtubs, or fill Florida’s Lake Okeechobee three times over! The typical American family uses 69.3 gallons of water in the home every single day.
