The utility companies and big ag use more than 92% of the water in California, and are not held accountable.
Meanwhile, cities charge a flat rate that varies very little between frugal and extremely wasteful households.
My water use is less than 1/30th of the average, but the city charges me 90%+ of an average household. Those using 100 times as much pay only a little bit more. All sewer, meter and waste pickup charges should be in proportion to household water usage, but that isn't done. Just like big ag and PG&E, those in charge want everyone else to pay for their wasteful excesses.
