NOW THAT LOW-FLOW TOILETS, SHOWERHEADS AND FAUCETS HAVE GONE MAINSTREAM you might expect that home water usage would decline each year. Not so. The latest available data from the U.S. Geological Service tells us that total water demand has leveled off for several years.
Are we using less per person? Yes. The population in the United States rises by about 5% each year, so by maintaining the same overall water use, we are making modest gains in water efficiency. But as author, law professor, and water expert Robert Glennon points out, simply treading water is not good enough.
