If you are sure it has reasonably low mineralization, you could probably use the recommendations of the Water Primer in the Brewing Science section of this forum. I prefer adding a modest sulfate content to my hoppy beers to accentuate bittering and the hops. You may or may not.
It would be wise to find out more about the Secondary Parameters of your tap water from the water company or have the water tested on your own. That is the best way to figure out what you do and don't want to add to your brewing water.
Check out the Bru'n Water website too. The Water Knowledge page may be useful in helping you understand where you're going with water adjustments.
