Current Residential Water Use: <br />the REU2016 Study <br />The homes studied in REU2016 showed an average annual use of <br />88,000 gallons per household per year (gphy)' <br />Annual Use <br />In REU2016, approximately 1,000 single-family residential accounts were randomly selected from each of <br />23 study sites (see Figure 8). Billing records showed average annual per household water use ranging from <br />44,000 to 175,000 gphy. <br />The large range in use reflects the strong influence of climate and weather patterns. Agencies participating <br />in the study come from across the United States and Canada and encompass a tremendous geographic and <br />climactic diversity. Outdoor use is more variable than indoor use, and homes in warmer climates have higher <br />outdoor use, continuing to irrigate in winter. <br />A fundamental goal of REU2016 was to quantify how much water is used both indoors and outdoors, as well <br />as per capita and household. Such metrics are valuable for understanding water use patterns, establishing <br />efficiency levels, and developing predictive models of future demand. <br />'This REU2016 statistic is based on 23,749 homes (23 study sites, mostly 2010 billing data) with a standard deviation of 32,000 gphy. The <br />median annual water use was 83,000 gphy. <br />4 1 RESIDENTIAL END USESOF WATER, VERSION 2: EXECUTIVE REPORT <br />
