Right, but this is not what is reported by "water consumption". It would be much better to have some kind of index (probably multiple) that estimates how close a particular feature of the water system is to a problem. Is the temperature too high, is there too high a concentration of some contaminant, etc etc.

You are make a semantic distinction here, but "consumptive use" is a term of art in modelling water usage: https://en.wikipedia.org/wiki/Consumptive_water_use
