They need to add water prices to that list. I just heard on the radio that the California Public Utilities Commission just approved tiered rates for water bills. We already have tiered rates for elctricity.
Tiered rates means you get charged different amounts for each amount you use over a certain amount.
baseline usage 259.90000 kwh@ $0.11556
101-130% of baseline 77.97000 kwh@ 0.13139
131-200% of baseline 181.93000 kwh@ 0.22708
201-300% of baseline 120.3667 kwh@ 0.31555
That is straight from my PG&E bill. They are going to do the same for water bills.
I pay about 1/2 of that for all kWH (see http://www.alleghenypower.com/Tariffs/VA/59673_VARetailTariff.PDF, Schedule R)
