Not living there, I can't comment on your city water.
I purchase RO water and build from there with Gypsum, Calcium Chloride, Epsom salt, pickling salt, and lactic acid. This allows me to build whatever profile suits the style I am brewing. I had no idea what the profile of my city water was, and they use chloromine, so this was just the easiest way for me. Only pennies a pint more to buy the water. I found an instant improvement to my beer.
