How much cranberry juice and water should you drink daily to get rid of uti?

None: Cranberry juice does not get rid of UTI (rx bacterial infection of bladder), but may be helpful to prevent UTI (has hippuric acid, keeps bacteria from latching on). Antibiotic is much better to rx active infection. Drink "plenty" of water and other beverages (8 glasses/day is good target); can get some of this from soups, juices, fruit. If irritated bladder, symptoms can be worsened by caffeine.
