According to the European Journal of Clinical Nutrition, "drinking three or more cups of tea a day is as good for you as drinking plenty of water and may even have extra health benefits."
Though it's been touted to have antioxidant properties, there has still been a common belief that tea is dehydrating because of caffeine content. However, UK nutritionists have found that tea rehydrates as well as water. Dr. Carrie Ruxton, public health nutritionist, said that "even if you had a really, really strong cup of tea or coffee, which is quite hard to make, you would still have a net gain of fluid."
In fact, tea is healthier than water overall because while water simply replaces fluids, tea replaces fluids and provides flavonoids and other compounds that promote health: reduction of rick of heart attack, protection against cancer, strengthening of bones, and protection against tooth plaque and potentially tooth decay.
I wouldn't necessarily go replacing water with tea, but if you're drinking lots of soda or juices with high sugar-content, perhaps tea is a better option.
