Sweet Water

I believe you are referring to "sweet tea," which is a popular beverage in the United States, particularly in the southern region. Sweet tea is a sweetened, iced tea made by adding large amounts of sugar or simple syrup to black tea while it is still hot, then serving it over ice.

The level of sweetness can vary, with some regions and establishments serving it very sweet and others offering a less sweet version. It is commonly found in restaurants and is often served as a complementary beverage with meals in certain regions.

If you are looking for sweet water, it might be a good idea to ask for sweet tea instead, as it is a more commonly used term in the USA. I hope this information helps! Let me know if you have any other questions.
