300 gallons
In L.A. County, Beverly Hills residents used 286 gallons per person daily, while Compton residents used 65. In posh parts of northern San Diego County, residents on average used more than 580 gallons of water a day in September. The average American family uses more than 300 gallons of water per day at home. Roughly 70 percent of this use occurs indoors. Nationally, outdoor water use accounts for 30 percent of household use yet can be much higher in drier parts of the country and in more water-intensive landscapes. The study found that about 53 percent of total average household water use — or more than 190 gallons per household per day — was used for landscaping and other outdoor uses (remember, this is only the state average — most cities in the Bay Area use significantly less). An often-cited 2011 study of California single-family water consumption estimated that the average California household used more than 360 gallons of water per day. To put that in perspective, the typical office water cooler holds 5 gallons, or about 1.4 percent of the study’s estimated daily average household use. Average Water Use. Water consumption levels vary throughout Australia. Average daily water use ranges from as little as 100 litres per person in some coastal areas to more than 800 litres per person in the dry inland areas. The current average daily water consumption is 340 litres per person, or 900 litres per household. In addition, an average of 150 litres of water per person is used every day in the workplace by industry and commerce, community uses such as watering of public parks and gardens, firefighting and system leakage. The size of the circles shows daily residential water use, in gallons per capita. The colors show how far above or below the state average of 77142 gallons those areas used in February 2015in July 2014. Many factors influence residential water use, like climate, income, lot size and types of homes. Meanwhile, Indoor use accounted for more than 170 gallons per household per day. Not surprisingly, the most in-home water consumption was in toilet flushes. A more shocking finding, however, was the whopping 18 percent lost to leaks inside homes. The average American family of four uses 400 gallons of water per day. On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
