Washing cloth diapers at home uses 50 to 70 gallons of water every three days, which is roughly equivalent to flushing the toilet 15 times a day, unless the user has a high-efficiency washing machine. An average diaper service puts its diapers through an average of 13 water changes, but uses less water and energy per diaper than one laundry load at home.
