Example from the article: "326,000 gallons (1.23 million liters), is enough water to supply one or two households for a year."
No! That is enough for >16 households a year in this rich part of northwestern Europe [0]. In a naturally dry area, consumption should be substantially less, not 16 times more.
Lowering residential water consumption to these reasonable levels gives an immediate 18.80% savings on total water consumption. That's nothing to sneeze at.
Forcing responsible water use upon non-agricultural users might also encourage a critical look at agricultural water consumption.
