Are the microfiltration/reverse osmosis/UV treatment/Hydrogen Peroxide

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.
