Dear Esther,

Others have correctly commented on the possible over-definition of the purification using RO.  It will be best to start with the desired end product - including whether this would be FREE distribution or require a fee to obtain the water from the kiosks.  Then the actual delivery process can start with the city water supply.  Is it not adequate in terms of purity?  If not, then as a city water supply, how does that affect other uses, and specifically, what would be the final purity requirements for your intended use?  Is such a distribution regulated by local or other government ordinances? 

I have extensive experience in localized carbonation for beverages, but that is simply an add-on to the water provided.  That would certainly affect the cost of the installations and their continued maintenance.  As a private venture that can be addressed by normal market forces.  If it is part of a municipal benefit, the city may have its own specifications or restraints on installation cost and maintenance.

I can explore some of the general considerations of both the technical and business parts of such a venture in some more depth before it would warrant any formal contractual agreement.  I may be contacted at drwhocooke@yahoo.com for further discussions.

Best regards,

Steven
