Past threads have emphasized the need for country folks to have generators to run their wells....but I have heard no mention about those living in the cities getting their water from huge wells run by the city. If SHTF, and all electricity is lost, including backup generators, people living in the city are as much up a creek as us living in the country for that matter. The size of generators it would take to run those giant wells in the city would need to be enormous. I don't see how they could keep that up very long.
