That was a good one.
That would be some scary water bills. But I do not know how big her yard is. The one that paid up to $800 a month. That would be what around 170,000 gallons a month that is insane to start with. What about more average users? Still there is without a doubt a shortage. Our rate with lake Michigan water is $1.64/1,000 with no increase in the rate with extra usage I have seen. As a single person the last 3 months I used just 4,000. That is with a fair amount of plant watering.
It is good for some using a lot let them pay that 4.58 or more. Then maybe they will get it.

Edited to add we must have a minimum for water. This 3 months with more watering used 2,000 more but same charge of $24.42.
