My manufacturing facilty has more than one kind of process type water user, and they are very distinct. LEED says "Meter at least 80% of expected daily water consumption for process type end uses," (pg 93 LEED Reference Guide EBOM 2009). I'm wondering if this means if I have to meter 80% of all of my process waters or just 80% of one type of process water? For example: One process use is for cleaning parts and another is for coolant. Do I have to do 80% of both combined, or could I just do 80% of the coolant system?

It's 80% of ALL the water that is going to process...not each process...HOWEVER I would suggest that you do sub-submeter each individual process water use as well. There is a long list of options for re-use of process water that can significantly reduce potable water use. (Potable water initial use for cleaning parts, re-used a second time for cooling, reused a third time for flushing or irrigation) By sub-submetering the ROI can be clearly explained to the 'boss' .
