Well the idea is that by having the water supply taken care of (by building on top of existing water infrastructure) keeping systems running would involve just replacing industrial-level filters. Of course, we're assuming that implementing this type of process would work under a reasonable budget. If there isn't a water supply to tap into, I think that problem should be addressed first, before making drinking water a priority.
Ah, true. The overhead on this idea is pretty steep, and a scalable implementation does indeed assume that water is reasonably available. We were thinking downtown Los Angeles or Santa Monica would be a good place to start, if this idea was brought to fruition. I hope the water challenges in India can be resolved so ideas like Water2Go could be implemented over there. Thanks for the the response Manoj!
