Using this metric, A 200MVA boiler would have an upkeep of $2.1 million per week. A 1000:1 converstion to CS currency makes it about 2100 per week. For water usage, enthalpy of vaporization (to get liquid water to boil, pressurize, and do work) -- about 3 cubic meters per kwh, or about 100,000 cubic meters per week for a 200MVA boiler, which, interestingly, is about one pumping station.
One dedicated pumping station to supply a 200MVA coal-fired boiler, except that boiling water to make steam put a turbine in motion is inherently inefficient. So figure three pumping stations.
FWIW, 99% of the water used goes right back in the river just as clean as it was (maybe cleaner). The rest goes out the cooling towers, much of which falls as rain or snow and (surprise) also winds up back in the river where it came from.
For reference, the Colorado river inflow to lake mead averages about 20,000 cfs. The Ohio river at Cairo, Illinois discharges about 250,000 cfs into the Mississippi.
