You must have a well and pump, right? If I am on city water, it still works when electricity goes out.... right?
Generally yes. They probably have an elevated water tank and pumps on a generator.
No, we have city water but....
Sometimes during real bad storms the power flickers at the treatment plant and they issue a don’t drink warning for a little while.
The water battles are the size the kids take to school and drink around the house anyway so we stock up when bad weather threatens.
