What Does This Mean?


  • Average daily household water use: 350 gallons
  • Average household water use annually: 127,400 gallons
  • If all U.S. households installed water-saving features, water use would decrease by 30%, saving an estimated 5.4 billion gallons per day. This would result in dollar-volume savings of $11.3 million per day or more than $4 billion per year.
  • Water-conserving fixtures installed in U.S. households in 1998 alone save 44 million gallons of water every day, resulting in total dollar-value savings of more than $33.6 million per year.
