The problem with tap water is all the tanks & cisterns that are cross connected. When city water fails (and it does) the content of the tanks flow back into the city water system. It will take years and lots of money to fix that issue. For what little water you'll ingest it's not that expensive or difficult to use bottled water.
Folks will tell you that you can filter or treat the water, and maybe you can and get away with it. But for me I'd rather be safe than save a couple of dollars.
