I would definitely go with a water collection system that allows water on a metal roof to be channeled through a gutter system into 275 gallon IBC tanks (the ones with the cage around them).
This water could then be treated, and filtered.

As far as waste, composting toilets will alleviate the need for a septic system, and any grey water could be used in a green house, or garden'

Colorado has many full days of sunshine, so solar panels, into a controller, through a series of deep cycle batteries, into an inverter to get 110 volt AC, would be the most efficient, and may still qualify for some government grants.

If you have a supply of firewood, and are building a home, you can do a "cordwood" design where the walls are actually built with split seasoned, firewood, laid horizontally with the cut end showing, surrounded by an inch or two of mortor. (cut to whatever thickness you want the walls to be).

I would also build a rocket mass stove into the design for efficient burning with much thermal mass.
