I lived on a ranch with a well and I never shut down my well even when temperatures were single digit and for extending hard freezes.
My well was enclosed and critical electrical components were kept warm and heated with simple heat lamps and light bulbs. There is more components with El Paso Water Utilities but its the same principle. The EP wells were shut down, and of course the lack of movement and flow of water (also no heating elements) caused infrastructure failures of piping.
