You’ll want to check out this article by Christopher Ingraham in the Washington Post that covers a new report by the U.S. Geological Survey (https://wapo.st/2lzlGUR). USGS reports that in per capita terms, water use by Americans has dropped from 112 gallons per days in 1980 to 82 gallons per day in 2015, a 27 percent reduction. Much credit is given to EPAct ’92, which set standards for water consumption in toilets, as well as bathroom and kitchen faucets, and shower heads.
One feature that’s exceptionally valuable in this story is the more than a dozen links to other background data, including to the text of the USGS report.
Despite the 27 percent improvement in American’s water consumption habits, Ingraham points out:
While our average per capita home water use is declining, it remains much higher than in other wealthy nations, including the United Kingdom (37 gallons per day) and Germany (32 gallons). Part of the issue is that water in the United States remains very cheap relative to other countries, which has led some economists to call for smarter, more flexible pricing schemes in America’s water markets.
To put it all in perspective, Ingraham notes that domestic water use is only one percent of U.S. consumption, compered with 41 percent for thermoelectric power and 37 percent for agriculture.
