Assuming $0.25/kWh (a very high electricity price), that's $0.90 per kiloliter (264 gallons). No one's going to die of dehydration at those prices, though sanitation may become expensive in poorer areas. (With the obvious public health implications...) At that price greywater reuse and low-flow everything become obviously worthwhile. It boggles my mind that the average American uses 100 gallons of water per day, but that's partially because of how cheap water is.
