Here in California looking for advice on water usage. No engineer in our Northern California area has been able to come up with a water treatment or usage estimate due to the fact that all of this is so new to their industry here. The city officials have approved one license after the growers obtained a copy of an Oregon commercial indoor growers water usage bill, using that as their rough estimate. Basically, my city is clueless on this and we are one of the guinea pigs. I know its a long shot but if anyone would be willing to share some info feel free to private message me or just reply here.
