Same for the water utility.
And the water company contract forbids using any water from my own sources-so. I do without theirs.
A workable and economic solution is determine what you absolutely must keep powered and size your solar/wind/standby generator/battery bank to keep those things working.
You can cook and heat water on your outdoor propane grill.Keep a full tank secured OUTSIDE in a fairly well ventilated structure. A can or three of gasoline with stabilizer added to the fuel for a modest sized generator.(run it at least every 90 days ).
