Give a pitcher of water a little boost of flavor (or a lot) with ripe fruit and fresh herbs. For a quart of water, gently crush a handful of aromatic leaves (like mint) and cube or slice about 1 cup of ripe fruit. Let it sit in the fridge overnight, and then strain out the leaves and fruit for a lightly flavored water. Sweeten if desired.
For more flavor and fiber, make an agua fresca. Skip the overnight soak and puree the fruit and water together in a blender. You can strain out the pulp for a clear, light beverage, or leave the fruit pulp in and just give it a stir or a shake before serving. Garnish with fresh herbs if desired. You can also make an herbal infusion (soak the herbs overnight in water, or brew as a tea with hot water), and remove the leaves before blending the water and fruit together.
Some flavor combinations to try:

cantaloupe + mint
cucumber + lemon + mint
