Scaling up rainwater harvesting technique for application on industrial site.
I just found out a pdf of a very good book on rainwater harvesting, attributed to your organization, as follows:

Douglas Kingman, Sam Houston State University

Brent Clayton, Texas AgriLife Extension Service
I am a freelancer consultant and have started a discussion on the LinkedIn, as follows; I wonder if this topic has been covered by your esteemed organization elsewhere and kindly provide a literature thereof :===========
The rainwater harvesting and watershed management are a technology per se, on residential and commercial buildings, urban area and hinterlands. How about adopting the same on the process plant sites?Mashallah Ali-AhyaieFreelancer Consultan===========
And finally let me comment that you have provided a very good model of contacting format, just as good as your above-mentioned publication.

Dear Mr. Raison,http://ohioline.osu.edu/ws-fact/
Thanks for the following links provided:
Yes these links are useful, as far as looking at the whole area covered by an industrial infrastructures, as an integrated watershed. But consider that many industrial plants need potable water, sanitary water, fire fighting water, plant water, cooling water, cooling tower make-ups, demineralized water used for boiler feed water, etc. Consider if a segregated sewage system is spared only for rainwater, all over an industrial plant, collecting all rain water therefrom, and combining all other harvested rainwater from different sections of the industrial watershed, such as landscape, office buildings, and the like; a good quantity of rain water could be collected to satisfy a very good supply for services like cooling tower make-ups, boiler feed-water conditioning units, etc., considering that rain water is almost pure with less than 10 mg/L of TDS. As such, treating rainwater to be used for boiler feed water, and the like will be much much cheaper in comparison to other sources of water supply. That is the main target which will compensate any investment on the rainwater harvesting on industrial sites.
These are the issues that I have in mind and am wondering if they are already considered anywhere.
The Texas websites that you have found are the most extensive that we have in the US. I will refer you to them and your other question that I answered on the same subject. We have had much better adoption of the technology on personal homes than in industries. We are work on that, but the corporate world is conservative and does not make changes quickly.
A Montana information sheet has the ability to be scaleable. The equations are in SAE units but conversion to international units is fairly easy. They quote that about 65% can be potable and 20-25% is captured in the roof washer system, the remaining is lost to leaks and evaporation.
The wasted water from what they call the roof washer, would have the good potential use for saving and using in most industries. Not all uses need potable water.
