As far as I understand, OC purifies the sewage to quality of distilled water (using above), and then pump it back into their aquifiers.

Ok, so ABQ is spending about $140 per person on that plant ($70 million for 500,000 people). OC is spending $96 per person on theirs ($480 million for 5 million people). It seems to me that the more sophisticated OC technology is cheaper. Presumably there are economies of scale, but $70 million is still a big chunk of change.
