It wouldn’t take a lot of ingenuity to recapture, filter and purify condensate from heat pumps and air conditioners in humid climates. Probably would produce between five to ten gallons a day, per household. Rainwater is viable anywhere outside arid regions. Then, there’s desalinization, which the left seems to want to pretend doesn’t exist for some odd reason.
In the summer I keep a big bucket under the a/c drain outside. Collect 6-10 gallons a day, depending on humidity levels
The Left is only interested in urban large-scale solutions (_never_ in truly independent home-scale systems), and the cities they’re only interested in are so large desalination plants would require nuclear power to operate - and since that’s absolutely intolerable per their sociopolitical axioms, desalination simply disappears as an option for them to consider.
I set a bucket under the A/C drain last summer. Easy 5 gallons a day, and that was during the drier times. That’s distilled water, the only concern really being the system it’s coming from isn’t “food grade”. Quick filter + UV and it would do pretty well in a pinch (assuming A/C still running; that points to another discussion about solar-powered HVAC...).
Since most water use need not be “potable”, roof runoff into a large cistern/container should be sufficient.
I’ve also taken to (at my wife’s concerted annoyance) putting large cheap baking pans outside during heavy rains and consuming the lightly filtered results. (Survivalism is something you _live_, not just prepare for.) Am considering how to set up larger food-grade plastic tarps to collect ever more when opportunity arises.
