A typical American uses 80 to 100 gallons of water a day, according to the U.S. Geological Survey. In total, the U.S. uses about 323 billion gallons per day of surface water and another 84.5 billion gallons of ground water. Every drop of water that goes to a tap in the U.S. gets treated to drinking water quality standards, but there’s a cost to treating that water. What if every drop of water we clean could be used twice? With continued water shortages, utilities are starting to look harder for opportunities to reclaim and reuse water before it gets cleaned to drinking water standards again.
