RO water

But are you really? Take into account the cost of replacing filters every few months. Having a TDS meter and keeping it calibrated (because you can't sell poor quality water). And then the cost of water -- for every 1 gallon produced, 4 to 5 gallons of waste water go down the drain. How about your time? What is the time that you spend making water worth? Will you provide containers to your customers, or do they need to bring their own? If you provide containers and sell it in bottles or jugs, how about that cost? At 5 cents a gallon, are you making money, or losing money?
 
Not to mention, you'd have to sell 20 gallons to make $1. If you have a 100 gallon per day unit, that's about 5 hours to make 20 gallons. In other words, you'll be making $1 every 5 hours, or 20 cents per hour, not taking into account all the costs I listed above.

Might as well move to Sri Lanka for that type of wage!

Holy crap, he's in the negative when you lay it all out like that.
 
AND factor in that a 100 gpd unit cost around $150. And ignore all the other costs for now -- just think about the cost of the unit alone.

You would have to sell 3,000 gallons of water at 5 cents per gallon -- or spend 720 hours making water (that's 30 days straight, day and night, working 24 hours a day) just to make up the cost of the unit!
