Citing longstanding complaints about wet and smelly restroom floors in its headquarters in Sacramento, the California Environmental Protection Agency has removed its 56 waterless urinals. According to KCRA-TV the devices are estimated to have saved about a million gallons of water during their service life of six years.
The urinals were state of the art technology when they were installed in 2004. They have been replaced by low-flow urinals that use about a half-gallon of water per flush.
Globally it's estimated that humans flush down the drain up to 20 percent of the supply of potable water.
