The records show that efficiencies can indeed foster per-capita decreases in consumption, but it may come as a surprise to many that, at the community level, the drive to enhance efficiency usually results in an increase in overall water consumption!
The timing might seem odd, even self-destructive. Los Angeles Mayor Eric Garcetti issued an executive order calling for his southern California city to cut its water imports by half within a decade.
