Well said. The break even would depend on the alternative water system costs, and, except in USVI and Key West, selling a house that operates on rainwater harvesting might be tough.

OTOH Fresh water supplies are dwindling, demand is increasing, and the states surrounding the Great Lakes have formed a pact to prevent exporting lake water to other states. Infrastructure like water and sewer lines are deteriorating, and electric generation is becoming problematic due to disenchantment with atomic energy systems. Perhaps the home of the future will need to be self sufficient in water, sewer, and electrical service.
